Ok, in the last decade and a half that I've owned only manual transmission vehicles, I seem to have lost my touch for getting a transmission pan to seal.
I recently picked up an '88 silverado with a 700r4 trans. The truck had been parked for several years after the trans had been rebuilt, has about 6k on the rebuild according to the invoice for the work. Since I began driving it, it developed a leak. So, I figured since it had been setting so long, I would throw in a new filter and gasket.
Now the old gasket was cork and the new one is rubber, so I installed it with no sealant. Now the leak is worse. Bad enough that I began to suspect the input shaft seal on the trans. Checked that tonight after work. Dry as a bone, so that's good.
Now in years past I never had this problem, but as I have said, I seem to have lost the touch. I would like to stay away from using just sealant, as this truck is going to be a parts chaser and see regular driving duties, so it will get regular filter and fluid changes on the trans and I don't want to scrape sealant off every time.
I've checked Fluid Lockers website along with Fel-Pro and Cometic. Fluid locker is the only one that offered trans gaskets, but not for the 700r4.
So, should I abandon the rubber gasket and go back to the cork? What have you guys used, and what worked or didn't?
