SF: Please advise me on how to replace transmission pan seal on a 1997 GMC Sierra pick up automatic transmission. (1500 2 W/D) Thanks.
SF: If you are going to do it yourself, be ready to have a mess on the garage floor. The best way I have found is to remove the rear 4-6 bolts first. Then work your way toward the front by removing 1 at a time from each side. When you get to the front 4-6 bolts, back them out less than half-way so the fluid will start to run out the rear of the pan. Let fluid drain out rear for a while, then hold your hand on the pan to position it back flush with the trans., then remove remaining bolts and SLOWLY lower the pan. No real way to not spill. Clean off magnet in the pan, clean off gasket mating surfaces on pan and trans., install new gasket on pan and raise into position. Install a few bolts by hand so pan will stay up by itself, then install remaining bolts by hand. Tighten bolts from the center of each side and proceed outward.
