Frequently Asked Questions (FAQs)

1. What gaskets are on a transmission?

There are several types of gaskets found on a transmission, including the transmission pan gasket, transfer case gasket set, transmission gasket set, universal automatic transmission power take off gasket, overdrive shift button kit, performance manual trans gasket set, and transfer case drain plug gasket.

2. How do I know if my transmission gasket is bad?

Signs of a bad transmission gasket include a puddle of automatic transmission fluid under the vehicle, low transmission fluid levels, and transmission slippage or other performance issues resulting from low fluid levels.

3. Can I change transmission gasket myself?

Yes, changing a transmission pan gasket is a job that can be done by yourself with basic tools. All you need are rubber gloves, hand tools, and an inch-pound torque wrench to successfully change the transmission pan gasket in your car.

4. Can you drive with a bad transmission seal?

While it may be safe to drive with a leaking transmission, it is not advisable. It is recommended to fix the problem as soon as possible.

5. What causes transmission gasket to leak?

One of the main causes of transmission gasket leaks is a cracked pan gasket. If there is any damage or fray in the gasket, it will need to be replaced as the fluid will continue to seep out. This is a relatively easy fix that requires purchasing a new gasket.

When a transmission seal goes bad, it can lead to fluid leaks that can burn up the transmission unit. Despite being small parts, seal and gasket failures are likely to result in full transmission failure.
