These transmission pans get "out of shape" due to over-torquing the bolts. That crushes the stops (see below), and when that happens, it is very hard to get the pan seal not to leak. Your best option if you are doing a transmission service is to replace the pan.

These are the stop tabs that get damaged.
We are firm believers is using special strong magnets in the pan to latch on to any metal particles. The factory does this is the 722.9 transmissions. 2 magnets are included to place in the center rear of this new pan.
Here is a list of models this pan will fit.
