To reduce the stress between two meeting parts in a vehicle, it's important to keep them lubricated at all times. Lubrication will help reduce the heat that is produced by friction, making the parts last longer. The transmission pan basically serves as the vehicle's transmission fluid reservoir.when your car is not in use, the pan keeps the fluid in just like a catch basin. However, since it is constantly exposed to extreme conditions, this component will inevitably get damaged and cause a leak over time. To prevent this from happening, the best thing that you can do is address a glitch when it comes up. Find out how by reading the guide below.
Tips for Fixing a Transmission Pan Leak
1. Find the source of the leak. Before replacing the busted pan in your vehicle, look for the source of the leak by wiping it clean. After that, drive for a short while and identify the source of the problem.
2. Ensure that everything is sealed. Use a socket wrench to torque the bolts of the pan and make sure that nothing is loose. You should also check the threads of the bolts if they are already damaged. If the threads are loose, you can try applying some thread locker on the component to seal it and prevent corrosion.
3. Do not reuse gaskets. If the leak is coming from the drain plug of the pan, you'd better replace the gasket of the plug. As much as possible, avoid reusing gasket after doing repairs.
4. Do not reuse o-rings. When changing your transmission fluid filter, it would be best to change you o-rings to ensure maximum performance.
5. Apply transmission fluid with stop leak. To recondition old seals and prevent them from hardening and causing leaks, you can use a transmission fluid with stop leak, especially if your ride has travelled beyond 75,000 miles. Just make sure that the additive matches your vehicle's transmission fluid.
Replacing a Transmission Pan
Step 1: To begin, engage the parking brake of the vehicle and then raise its front end using a jack and support it using jack stands. Next, locate the transmission pan and place a large draining container beneath it.
Step 2: After that, use a wrench to remove the bolts that secure the pan in place and then tap its corner to break its gasket seal. To drain the fluid, tilt the pan and let the fluid flow to the draining container.
Step 3: After draining, remove the remaining bolts of the pan and take it out from the vehicle completely. Make sure you remove the traces of the sealant with the help of a gasket sealer.
Step 4: Next, smear RTV sealant all over the sealing surface of the new pan. And after that, mount it onto the mating surface of the transmission and secure it in place using its mounting bolts. Make sure you use the wrench in a crisscross pattern.
Step 5: When you're done, lower the vehicle and replenish the transmission fluid before you go out and take your vehicle for a test drive.
