Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Perform Repair
An automatic transmission contains over 400 individual components. All of these components must be in good working order. Many repairs are fairly straightforward. In these repairs you will:
- Clean and inspect all removed parts
- Attempt to determine the root cause of the failure
- Identify and repair/replace any related damaged parts
- Carefully document findings on the repair order
In the case of clutch failure where the transmission fluid is heavily contaminated with friction material, the transmission needs to be overhauled. The repair requires complete disassembly and cleaning of the transmission. All seals and gaskets (except the reusable pan gaskets) should be replaced.
