Possible Causes and Solutions for Cadillac Transmission Leaks

As part of your regular maintenance schedule, you should change the transmission fluid to keep it running smoothly. Here are some of the things to look for if your transmission starts to give you trouble shifting or stops running.

Fluid Levels

Usually, a well-maintained transmission doesn't give you any problems, but transmissions have seals, gaskets and lines that can develop leaks. Leaking transmissions will eventually lose all their fluids. A seal or gasket can age and crack, and that can cause a leak. You may even have coolant in your transmission fluid, which is a cross-contamination of fluids.

You should check your fluid levels, and if you see that it is low, you need to find out where the leak is. A common symptom of falling fluid levels is a slipping of the gears or the car shifts slow. Find the leak and repair it. If you have not changed the fluid in long time, have the transmission flushed and filled with new fluids.

Torque Converter

A torque converter can become worn out over time, or it can have broken needle bearings. If the torque converter goes bad, it can do great damage, including failure, to your transmission. You may hear odd noises occurring when you shift gears. You will not hear this while it is in neutral.

Test the torque converter and replace or repair it as needed. This should eliminate the problem and keep the transmission from becoming damaged.


The fluids flow through the transmission under the control of the solenoid. The solenoid can become damaged due to fluid levels that are too low or electronic issues with the solenoid itself. You will find that the symptoms are similar to having a fluid leak. You will notice the transmission slipping. If you check and see no fluid leaks and the fluid levels are fine, then you can check the solenoid for the source of the problems with your transmission.


A clutch can become jammed. It is located in the torque convertor, and if it jams, the solenoid can be locked, which will incorrectly calculate the amount of transmission fluid needed. The symptoms are just like a low fluid level problem. However, your Cadillac may develop a violent shaking and high heat in the transmission. Your engine will drop sharply in power.

Anytime that you run into trouble with your transmission, it is imperative that you take care of the problem right away. A fix is always a more viable option than a complete transmission replacement. If you cannot diagnose your problem, take your vehicle to the nearest Cadillac dealership for assistance.
