My Transmission Will Not Shift!

Automatic TransmissionThe transmission is as necessary in a vehicle as the engine itself.  Imagine leaving your car in first gear and trying to maintain speed on the highway, or start from a dead stop in fifth gear.  Engines that are put in vehicles today are designed to run safely in a very specific range or speeds, or RPMs.  If you’ve ever noticed an area where the numbers turn red on your cars tachometer, it’s an indication of the upper limits of your engines ability to safely spin.  Also, automobile engines are designed to run efficiently in an even narrower window.  Since we all want to be able to operate our vehicles comfortably whether we are going 5 miles per hour in a parking lot, or 70 on the highway, we need a transmission coupled to the engine to turn its relatively low range of operating speeds into the wide range of desired speeds for a car.

The automatic transmission in your car surprisingly shares a lot of similarities with the early transmissions in the Ford Model T.  The backbone of most modern day automatics is still the planetary gear system which was used in the Model T.  Similar to a manual transmission, the teeth of the gears in an automatic transmission are always meshing.  In a manual transmission, when you select a different gear, what you really are doing is coupling a different set of gears to the input and output shafts in the transmission.  The theory is similar for an automatic transmission, but the gears are arranged in a much different way.

transmission not shiftingThe planetary gear set in an automatic transmission is named such because there is one large gear in the middle with smaller gears around it, much like a large sun with planets orbiting it.  There is also a third gear around those called the ring gear.  Different gear ratios are obtained by coupling the sun, the planet, or the ring gears either to the input shaft or the output shaft.  The gears that aren’t coupled to the input or output shaft may be held still, or allowed to rotate freely.  For a more thorough explanation check out:

Most automatic transmissions have two sets of planetary gears in them to accomplish all of the gear ratios needed to be useful in your car.  The difficult part is figuring out how to allow any of the gears in the transmission to be coupled either to the input shaft or the output shaft, be held stationary and be able to spin in either direction.  This is usually accomplished through a series of bands, wet clutches and springs.  These bands and clutches are designed to operate in a wet environment, meaning some lubricant should be present to ensure proper operation.  Also, the control of these devices is usually accomplished by fluid pressure that is controlled by your vehicle’s computer.

Transmission wont shiftThe fluid which creates the pressure to operate the clutches and bands as well as lubricate them is automatic transmission fluid.  If your transmission is running low on transmission fluid, the first symptom is usually a hard shifting condition, meaning your car will jolt forward when it shifts.  With enough fluid loss, your transmission will eventually be stuck in one gear.

The best solution is to add the correct amount of the manufacturer’s recommended transmission fluid along with BlueDevil’s Transmission Sealer.  Rather than struggling through finding the leak and possible expensive repair bills, use BlueDevil Transmission Sealer.  It is guaranteed to revitalize the seals in your transmission to stop any leaks making sure your transmission fluid stays at the proper level and your transmission continues to function properly.

Reasons Manual Transmission Wont Go Into Gear When Running And What To Do?

Have you ever been faced with a situation where your manual vehicle wouldn't go into gear with the engine running?

Well, this can be a frustrating position to be in if you are ever faced with it. A car won't go anywhere in the park. In order to drive you to have to shift it into first gear, but what if it won't go into first gear.

Well, there are a few things that can be going on, and after reading this, you will learn what those are. We will also provide some solutions for the common problems.

Reasons Manual Transmission Wont Go Into Gear When Running And What To Do

Reasons Manual Transmission Wont Go Into Gear

Before going into detail we will list out the main reasons, and if you think your issue is being caused by one of those, then you can jump straight to that section. If you don't know what is going on though, then you can just read through all the potential problems.

The common reasons why a manual transmission won't go into gear while driving is:

  • Parked on Incline
  • Clutch Problems
  • Low Fluids
  • Bad Transmission


1. Parked on Incline

Parked on Incline

The first thing that is pretty common to cause your car not to be able to go into gear while running is being parked on an incline. If you are parked on a hill, especially a steep one, then the car might not be able to go into gear because there is too much pressure on the park pawl. This pressure can cause it so it can't move out of the way when you try to put it in gear. Some pressure is good and needed though because that is what keeps your car from rolling down the hill while parked.

This problem is pretty easy to fix though if it is a problem you are having. All you have to do is roll the car a little. You shouldn't have to move it much to get the park pawl to loosen up. Then you can put your car into gear like normal and be able to go about your day. When moving the car, you can turn it off and sometimes you might be able to put it in gear with it off. If that is the case, then it will be even easier to roll your car a little to remove the pressure on the park pawl. If you are parked on a hill, then this is the first thing you should try.

2. Clutch Problems

The next thing that is the most common reason why a manual won't go into gear while running issues with the clutch. The clutch is the pedal on the floor that you have to press to shift. When you press it, it loosens the pressure plate and clutch disk. Then these move out of the way it allows the new gear to drop into place when shifting. If these are stuck or won't move, then you won't be able to put your car into gear.

The first thing that could cause the plate or disk not to move is if your clutch became disconnected. If the clutch wire broke, then it will not send the signal to the disk to move. You can get under the car to check if that is the problem and if it is, then you need a new clutch wire. Before getting under the car though, you can probably use feel to see if that is the problem. When you push the clutch to peddle in, if there is little or no resistance, then that is probably because the wire is broke. If the wire is not broke, then the clutch disk or pressure plate might just be worn out. The only way to know if they are worn out though is by dismantling the system and checking them.

Another thing that you can do though before dismantling is making sure you have enough transmission fluid and also the right type. Also, if you have resent flushed the fluid, then that might be why the plates aren't moving. The fluid gets pieces of metal in it over time, and sometimes it is these pieces of metal that are making contact with the plat to get it to move. If that is the problem, then things will need to be replaced. If the fluid is low though, then topping it off can help give it the fluid it needs to lubricate the pressure plate or clutch disk to help it move.

One way to narrow down if it is the clutch or something else is to use your ears when trying to shift. If you don't hear anything when trying to put it in gear, then odds are it is the clutch and not a different problem. Also, if you can put it in gear when off, but not on, then it is probably a clutch issue.

3. Low Fluids

Low Fluids

We have already touched on low fluids, but we will briefly explain here why the fluids are so important, and why it is so important to use the right ones.

The transmission fluid is responsible for lubricating the system and keeping heat from building up which can cause damage. If the fluid is low, then there may not be enough lubrication to allow things to shift. This is the least of your problems though.

The big issues come about when it is low, and heat builds up causing the gears to get damaged. If the gears expand and contract too much from heat, then they can crack, or teeth can break. Not enough lubrication can cause them to break as well though because you have metal rubbing against metal.

To minimize the metal on metal rubbing, you need to keep your fluids full. Also, you need to make sure you are using the right transmission fluid for your transmission. Some are thicker than others and handles heat differently. If you use the wrong type, then it might not be dissipating the heat right, or it might be too thick for the gears to move properly in.

4. Bad Transmission

Bad Transmission

The last reason why your car may not go into gear when running is the transmission itself could be damaged or bad.

The best way to determine if that is the case is to use your ears when trying to shift. If you hear grinding when trying to shift and you know the fluids are right, then odds are the gears in the transmission are damaged.

If the gears are damaged, then they won't lock into place right to put them into gear. If this is the case, then the only way to fix it is to have the transmission rebuilt. When you have the transmission rebuilt it might be one or two gears that need to be replaced, or it might be the whole thing. You don't know though until you get in their and tear it apart.

Using best bluetooth obd2 scanner to check your car is the best way to check bad transmission.

The best way to determine if the transmission needs to be rebuilt outside of using your ears is by trying to put the car into gear with the car off. If the car will not go into gear even when the car is off, then it is most likely a damaged transmission.


So as you can see, there are only a few things that can lead to a transmission not going into gear when running. If could be you are parked on too steep a hill, or it could be a fluid issue. These two are easy to fix.

The bigger ones that cost more to fix are if the clutch is bad or the pressure plate or clutch disk is bad. The worst of all though is if the transmission itself is bad. If that is the case, then it will need to be rebuilt. After reading this though you should be able to narrow down the problem you are having if your car won't go into gear when running and have an idea of where to start to fix the problem.



Let me put my 2-cents in, okay? Here’s a suggestion, look at the the engine control computer (ECU) first. If it has failed, it might force your engine to shutdown. Though I doubt it is honestly the central problem, it still is an area where you can start.

More importantly, get your vehicle over to a good independent shop with an updated set of error codes for your particular brand and ask them to run an OBD-II diagnostic. The readout should tell you the areas of failure in your engine or why it isn’t workng properly.

Once you have the listing you can then figure out how you want to proceed.

Just earballing it by reading your questions and comments, I’d say that the problem lies somewhere in the front end of the transmission, perhaps the torque converter or a related part. If the converter fails, then your vehicle won’t go or if it moves, it won’t move very far. If you are lucky then your vehicle goes into limp-home mode; you get one gear forward and perhaps reverse so that you can limp home or to the service area. However, since your vehicles aren’t moving, I’d suggest that the converter may be shot.

One other idea is that, as the ECU can fail, so can the transmission control unit (TCU) or the sensors used to feed information to the TCU or ECU. If any one of them or several of them have failed, then your vehicle won’t move, either.


Go wont rebuilt gear transmission into

It's a busy day, you are already running late, the motorway is bound to be packed, and the kids are irritable. Once the car is packed and ready to go, you strap in, start the car, and realize that your car won't go into gear. Your late crisis has now been upgraded to an automatic transmission car crisis. 

Auto Repairs Are EXPENSIVE


 If your car is having a day like you are and refuses to go into gear, it means you will not be going anywhere until you diagnose the cause of the problem. Knowing what the root cause is will help you determine the best solution to get moving again. 


If you are in this situation, then continue reading. This article will explain why your automatic transmission in your car won't go into gear.


Automatic Transmission System

Unfortunately, a transmission problem is as show-stopping for your car as an engine problem. This is because a car's transmission transfers the power from the engine to drive the wheels. 


Cars either have an automatic or a manual transmission system: 

  • Manual Transmissions: This is usually a sealed unit, so you do not need to add or check transmission fluid directly to this system. 
  • Automatic Transmissions: This multi-speed transmission does not need a driver to change gears when driving normally. Special sensors determine when the transmission should shift gears. The gears are changed using internal oil pressure. Transmission fluid needs to be checked and changed regularly if you have an automatic transmission system. 


Let's explore the automatic transmission system in further detail. The most important components to this transmission system are:

Next time you take a peek under the hood of your car, look for a cone-shaped metal case. That's the Bell Housing.


Front-wheel-drive cars have them on the engine's side, and rear-wheel-drives have them mounted underneath the car behind the engine.

Just because you are not shifting any gears does not mean that an automatic transmission does not have them. Modern automatic gearboxes are made with planetary gears.


This is a set of gears with a central gear known as the sun gear, an outer ring with internal gear teeth, and two or three gears called the planet gears that rotate.

Transmission fluid is critical in an automatic transmission car. The fluid is responsible for valve operation, brake band friction, and torque conversion. 


Transmission fluid is either red or green in color; this is to distinguish it from other fluids such as motor oil.

If you want your car to shift gears at the right time, the fluids need to be clean to make this happen. Your transmission has a filter that catches all the gunk.

Automatic Transmission Symptoms of Crisis

Below are some symptoms to keep an eye out for that are associated with automatic transmission problems. Should you be experiencing these problems, your car won't be able to go into gear soon: 


  • Grinding or Shaking Sensation When Shifting Gears

Normally this process is smooth; if you are experiencing grinding or slipping when your car changes gears, then this may be your first symptom of a transmission problem.


If there is a delay in response during gear changes, you could be experiencing a thickening of fluid that has degraded and needs to be replaced.


  • Clunking and Humming Noises

When these humming or clunking noises start, it is a sure sign of transmission trouble.

A humming noise is usually attributed to fluid breakdown. The result of this is that the fluid does not work properly to relieve friction.


A clunking noise means that there is already a part that is broken somewhere inside the transmission.


Unless you have deliberately set your car on fire, your car should never have a burning smell.


Fluid breakdown is the common cause of a burning smell. This breakdown causes friction between the transmission's components. This heats up and smells like something is burning. Have this checked out immediately.


If your car slips out of gear or loses traction while driving, you may have a serious problem.


The computer tells the car when to shift gears and sends power to the wheels. If there is a malfunction during this process, then the signal is not being sent, and there could be serious consequences.


If the “Check Engine” light is on, then you know there is a problem, even if it is a small one. 


Transmission problems can cause your engine light to come on. Unfortunately, this is not always as clear as other components within the engine. If the engine is under-performing, then your transmission will not respond because of the lack of power. 


Newer vehicles have a transmission light; in which case, the engine light will not come on to indicate a transmission problem. Instead, the transmission light will come on. Most vehicles manufactured after 2012 have the transmission warning light on the dashboard. 


This is when the vehicle goes into first gear and refuses to shift. This is one of the most dangerous scenarios.


The transmission shift solenoid could cause this. Make sure you know how to use the shift lock release should you get stuck in one gear. If not, you will be stuck with no power and one gear running the risk of completely burning out your engine.


Why Your Car Won't Go Into Gear


If your car won't go into gear, there could be a series of problems that are likely to end up costing you some money.


You may have received some warning signs before total failure. If there is a mechanical problem, you would be getting a lack of response from your car coupled with a distinct sound.

If that wasn't bad enough, transmission issues have been known to emit the smell of burning fuel, which may cause slight panic.


If your car won't go into gear and you have an automatic transmission system, then below are some of the possible causes: 


The most common reason why your car won't go into gear is that you have low transmission fluid. This is detrimental to your transmission system, but it could also be dangerous if the fluid leaks onto a hot pipe or surface of the engine. 


Is there a dark red puddle underneath your car in the driveway? If yes, then this is a sure sign that your transmission fluid is leaking from the gasket, a seal, or one of the cooler lines.


Remember always to maintain and check your transmission fluid levels. Regular services will also pick up an impending leak before it happens. If the transmission fluid thins out or is dirty, it can also stop your car from being able to change gears. 


  • Electrical Component Failure

Your automatic transmission system is a complex computer-driven system. Electrical issues in the car can cause automatic transmission problems, including early soft shifts, late harsh shifts, and no shifting at all. 


Sometimes when there is a glitch in the computer system, it may prevent your car from going into gear. Resetting the computer can also resolve the delay or problem. Simply disconnect the battery for approximately 30 minutes and reconnect.


The flexplate or flywheel is responsible for connecting the engine's output to the input of the torque connector. A broken flexplate will not transfer the proper engine power to the transmission. This means your car won't go into gear properly. 


  • Malfunctioning Shift Lock Release

You will find a Shift Lock or Shift Lock Release switch on early all modern car models with an automatic transmission. This switch is located near the shifter. To prevent your car from being accidentally put into gear when you are not present, many automatic transmissions will lock the shift knob into “Park” until you place your foot on the brake and start the engine.


In some instances, the shift gets stuck and fails to disengage properly. This will prevent your car from going into gear. The good news is that it is a quick fix, which you can do with the release key or a small screwdriver. 


Repair Costs


  • Transmission Fluid Change – depending on the severity, this is a simple fluid change and costs $80 – $250
  • Shift Solenoid Replacement – Most cars have two solenoids, making this cost slightly high from $150 – $400
  • Transmission Fluid Leak – Typically caused by a worn or damaged seal, this can cost around $200
  • Transmission Rebuild – Salvaging what you can and replacing as few parts as possible, a rebuild can cost from $2500 – $4500
  • Transmission Replacement – If the damage is irreparable, a completely rebuilt engine costs from $4000 – $8000


Transmission problems are two words repair companies love, and car owners hate. They tend to mean costly fixes and time without your car.


If you are at a loss and see no future with your car, there is an alternative way that you can still get rid of it and make some money at the same time. Contact Cash Cars Buyer. They will buy your damaged vehicle from you, and you can move onto buying a new car with fewer problems.

Transmission won't shift into second after rebuild

It sounds like the 1-2 and 2-3 (A/B) shift solenoids are continuing to be energized or are stuck in the on position. According to the 1994 Camaro/Firebird Service Manual (pg 7A-14A-6):

The PCM energizes each solenoid by grounding it through an internal quad driver. This sends current through the coil winding in the solenoid and moves the interal plunger out of the exhaust position. When 'ON', the solenoid redirects fluid to move a shift valve.

In order for the transmission to be in first gear only, both of these need to be energized, which makes me wonder: are you sure it's in first gear and not third gear? This could also be the case, mainly because 3rd gear happens when both solenoids are off. The general layout for the shift to solenoid operation looks thus:

Also, is there a check engine light which might be on? If so, get this read, as it will tell you if one of the solenoids is not operating correctly.

Did you get the electrical connector reseated properly? There are a dozen or so pins in the connector, one of which may have become bent when reinstalled. Pull the connector and ensure there aren't any major issues with dirt, crap, or bent pins (if for not other reason than to eliminate this as an issue).

Beyond that, without more information, I'd be at a loss.
