FAQ: How To Torque Transmission Pan Bolts?

Can you over tighten transmission pan bolts?

Over tightening the bolts can easily damage the pan of a transmission. The flange of the transmission pan should be flat and have no bulges. Over tightening the pan bolts causes the flange to distort.

What size are transmission pan bolts?

Pan bolts should be 8mm, probably 20mm long. Start the two rear bolts by hand using your socket. Do not run the bolts up too tight. If you drain the torque you should have drained most of the fluid from it so you can add all the recommended amount but for maybe a quart.

Is a deeper transmission pan worth it?

A deeper pan will only increase the time it takes to get up to temp. Provides more buffer through increased mass. Of course, it will also take longer to cool once it does. Your experience is why I don’t like those drain plug kits.

How do you fix a leaky transmission pan?

The best way to do this is to remove all of the bolts and have the pan dangle so that the fluid can come out slowly. After finding the specific pan for your vehicle and thoroughly draining out all of the transmission fluid, remove the bolts that hold the pan in place. Replace them with the new bolts and pan.
