How to Use a Transmission Jack? Easy Guide for Beginners

We are all familiar with the transmission in cars. It makes up for almost the entire underside of any vehicle.

Needless to say, transmission aids in the smooth power generation and driving of the car. But what if your car starts making clunking, whining, or humming sounds?

Most of the time, the issue is associated with transmission faults. And how do you even access the transmission of the car? Well, that is where the transmission jack comes up.

A transmission jack is a tool used to access the transmission of a car. It is typically used to remove or install transmissions in a car. Regardless of whether you are a hobbyist or a professional garage owner, you will need a transmission jack to repair and replace the transmission.

Uses of Transmission Jack?

It’s common knowledge that a transmission jack primarily serves the need to replace, repair or install a new transmission. But that doesn’t mean it’s all in one tool. There are all sorts of different transmission jacks, and they support different weight class cars and transmission setups.

A DIY person may be better off with just one type of transmission jack. However, for professional use, there are transmission jacks that come with a host of features for different types of transmissions.

A typical transmission jack can hold anywhere between 600 lbs. to 4,000 lbs. weight. Different types of transmission jacks work in different ways. But we won’t get into the technical parts. Let’s see how to use a transmission jack.

How to Use a Transmission Jack?

There are several steps to using a transmission jack. But before anything else, it is important to ensure proper safety precautions and measures. Another thing to take care of is the removal of the transmission fluid from the fluid pan right after lifting the car.

Step 1 – Lift the Car

Transmissions are usually bare on the underside of the car. As a result, hoisting up the car reveals the transmission. What you have to do is lift the car with a car lift. It should be approximately 60 inches off the floor.  Once the vehicle is up, the transmission should be visible.

Step 2 – Aligning the Transmission Jack

This step involves aligning the transmission jack with the transmission itself. Align the transmission jack in a way that the compressed air line is in line with the inlet valve found within the transmission jack. Make sure you get a secured fit.

Step 3 – Placing the Transmission

If you can connect the air valve properly, the transmission jack will align with the center. After that, you have to extend the arm of the transmission jack so that it reaches up to the fluid pan within the transmission.

Step 4 – Release the Air Pressure Valve

Once the transmission jack is aligned at the center and the hands are extended up to the fluid pan, it is time to release the air pressure valve. The air pressure valve is situated within the transmission jack. It will expand and push the transmission up within the vehicle. This will allow pressure to recede from the bolts holding the transmission to the vehicle.

Step 5 – Securing the Transmission with Jack

Up until this point, everything is textbook. The most important aspect of using a transmission jack is securing the transmission with the jack. It’s a fairly simple process.

The transmission jack plate will hold the transmission securely in its place.

For added protection, make sure to use the accessory strap to fasten the transmission with the jack properly. The plate can be used to move around the transmission for repair and reinstalling.

Step 6 – Reinstalling the Transmission

To reinstall, simply make sure that the transmission is aligned with the middle of the jack plate.

After that, align the transmission with the underside of the vehicle and push it up. Once the bolts are in place, use a securing screwdriver to bolt the transmission with the vehicle.

Many people make the rookie mistake of putting in the fluid before securing it with the vehicle. This has a chance of spilling. Make sure to put the liquid after installing it in the vehicle.

Final Words

Using a transmission jack is a fairly simple process. The hard part is finding the proper transmission jack for your use. Regardless, proper precautionary measures should be taken while lifting the car or using the jack itself. Always double-check every step to avoid mistakes as much as you can.
