Truck Won’t Move in Any Gear Automatic Transmission! [Solved]

A very common problem among truck users is that they keep their vehicle in gear but it does not move. Are you facing the same problem? Then there may be a transmission problem with your truck.

There are various reasons behind this problem. You may notice different offerings on your truck. So the question here is what could be the right solution to that problem? Since the causes of the problem are different, the solution should be various.

However, here, in this article, we will discuss how to solve this problem. We will also discuss what causes transmission problems, how to fix them, and how to avoid the problem.

Why Won’t A Automatic Transmission Truck Move In Any Gear?

First, we will look at the reasons why a truck does not move even after being put in gear. Knowing the reasons then we will come to a solution accordingly.

Faulty Automatic Transmission Control Unit

This is the most common reason why an automatic transmission truck does not move despite being in gear. It will easily catch your eye when you go looking for the cause.

To understand this some models have to move the transmission of the truck. In contrast, in some models are very easy to reach the transmission control unit.

When there is a problem with the control unit, those signs are visible on the truck’s dashboard. There you will see different or wrong gears being shown compared to the shifter.

Here you may need to test the car battery as an unsuitable battery can interfere with the performance of the control unit. To do this, take a multimeter and see if the reading is less than 12V. If all goes well there will be a need for more in-depth monitoring.

Poor Torque Converter

If the transmission problem is caused by a bad torque converter, then detection can be a bit of a hassle. However, there are some symptoms such as strange noise, high stall speed, fluid fouling, trembling, slipping, overheating, etc.

All of those are notable features of a faulty torque converter. Research says that in most cases the torque converter is not responsible for the underlying problem. For this, first, check the transmission and then come here.

Worn Clutch

The clutch works behind this technique when the transmission is active and inactive in a vehicle. This affects the power control unit when the clutch is damaged due to use. No vehicle, especially automatic transmissions, can run in any gear with a damaged clutch.

However, if the problem is centered on the clutch, the truck will not be able to move while in reverse gear. In addition, shifting to third gear produces an injury sound when changing.

Insufficient Transmission Fluid

When there is a shortage of transmission fluid in a vehicle, the gear system does not get the power needed to move. In this condition, the truck cannot move even if it is in gear because the transmission fluid is responsible for transferring power to a vehicle.

Impaired Automatic Transmission Valve Body

Hydraulic channels can be clogged due to various types of leaky or worn dirty transmission fluid. This may be another reason why your truck is not in any gear. If the body of the automatic transmission valve is faulty, the truck may vibrate or come to a standstill while shifting the gear.

If the body of the automatic transmission valve is damaged or damaged in any way, the solution will be the most complicated. Because in this case, the whole transmission may have to be removed from the vehicle.

How To Fix The Transmission of a Truck?

When you know the causes of a problem, it becomes easier to solve. Since we have learned why an auto transmission truck does not move despite being in any gear. Now we can come up with a solution accordingly.

Stage 1

Turn on the truck and apply the brakes. In this way, even if the car is in gear, it will not be able to run.

Stage 2

If your truck has a manual transmission system, you need to engage the shifter with gears. Sometimes it can be difficult to get the shifter into gear if you don’t press the clutch significantly. Disengage the clutch pedal when you put the shifter in gear. Otherwise, it can affect the gear.

Stage 3

In this case, if you have trouble starting the truck, try shifting the gear. It may even work if you don’t go into reverse gear. Thus, you can easily understand where the problem is.

Stage 4

At this stage, you need to check if your truck has enough transmission fluid. For this, find the dipstick of the truck. If you can’t find the location of the dipstick, check your truck’s manual.

Now check the transmission fluid. When this episode is complete, grab the truck’s brakes and turn it on. If you see that the level of fluid has decreased, add the appropriate amount of fluid.

If the problem is caused by insufficient transmission fluid, then it will not be seen again. Because you add fluid and bring its level to a tolerable level.

How to Prevent Automatic Transmission Problems?

If you do not take quick action, the problem of automatic transmission trucks can be even more complicated and expensive. For this reason, you can avoid the problem by following the following steps to avoid all such troubles.

Lesson 1:

Warm the truck before you are about to accelerate the car during winter. The truck transmission system may take quite a while to heat. Wait for this. Keep the truck in the first gear so that the engine does not increase.

Lesson 2:

The condition of the transmission oil reduces the quality day after day. Therefore, the quality and level of it should be examined regularly.

If the oil level is reduced, add more to adjust. In the form of metallic shaving, the signs of erosion should be understood during the transmission fuel replacement.

Lesson 3:

Before leaving the truck, shift the gear shift in all modes. Each mode should wait at least 5 to 10 seconds. Whatever it will be, the fuel can enter the hydraulic channels.

Lesson 4:

Automatic transmission vehicles, especially, are created to carry a certain load. Other vehicles cannot be towed. If very urgent, you can tow for a short distance. If you want to force and tow more weight, the trucks will not move in the gear with several damages.


When an automatic transmission truck does not move on gear, there are several reasons behind it. Specify the right reasons first then take action accordingly.

Test the level of transmission fluid and add if needed. Check the battery and its connection so that the automatic transmission control unit can supply the power to the truck.

These are the most common reasons. Apart from these, there may be even more complicated that prevent the truck from moving in gear. Whatever the problem, the solution is possible if appropriate action is taken.
