200-4R pan gasket
I have always had a leaking pan gasket on my 200-4R. I have replaced the gasket several times and tried cork and paper gaskets. I can't get good results on the forum search. Someone recommended the Car Quest gasket, P/N W3961TC. I have purchased this gasket. Does anyone know what torque to use on this gasket? I am considering an aluminum pan. Any recommendations?

Flatten the tranny oil pan rail, then stone it smooth before you reassemble it. Use a cork/synthetic combination gasket or a full-synthetic rubber gasket. Make sure that all bolt threads in the tranny case are in good condition; heli-coil any that are weak/damaged. Apply the bolt torque specified by the gasket manufacturer. Re-set torque on those bolts after about a week of operation by tightening only. If you reach required torque without bolt movement...leave it alone.
{Note: Your tranny pan is probably dimpled at the bolt holes from over-torquing the bolts in an attempt to get it to seal.}

Use a good Fiber gasket "Fel pro" and permatex hy tack spray.Clean the pan rail and transmission flange with lacquer thinner. Spray both sides of the gasket let it tack up and lay it on the pan,bolt it back up 6-10ft.lb on the bolts. Cork gaskets are junk.

Yes, cork is junk, I toss it every time, in the past, before good rubber gaskets were available, I used just plain old RTV after cleaning good with lacquer thinner or carb cleaner....let it set overnight before filing with fluid.....drove one for nearly a decade that way....I use RTV even with rubber gaskets, just for extra effort...I not much on any other sealant....

Yes, very important to do just this. Make sure the pan is clean and flat. I used to work at a NAPA parts store. They sell a Black synthetic gasket in their NAPA ATP line. (Automatic transmission parts) THey do also sell a cork/rubber gasket too. stay away from the cork/rubber. Don't use any sealer, RTV, or other sealant on the gasket. The holes are made in the gasket to hold the bolts as to not fall out. Always had great luck with these gaskets.
