$#@# leaking trans pan.

Good advice on the pan gaskets, guys.
In the past I have found that many of the torqflite leaks actually come from the selecter shaft seal. It is cheap and pretty easy to replace, just requires dropping the valve body. If you are in doubt about where the fluid is coming from, clean the area around the shift selecter well, and then watch that area carefully. If the trans is full, it will leak even without the engine running.
