Have 89 Iroc with 700r4 and 5.7 motor need to replace trans pan gasket...need torque specs to tighten pan bolts and do you all recommend rubber or cork gaskets...thanks larry

 

The bolts should just be "snug". I don't remember the material of the gasket I used but it's not cork.
I also like to use Gaskacinch...

 

Thanks T. L. for the info...another question how do you like the 2000 stall converter...i do a little drag racing and have a stock converter...350 motor, B and M shift kit and shifter, headers, 3.27 gears with a aftermarket cam..would like to get a better launch from the line... drag race enough to get my fill i am 71 years old now...never had a stall converter other than stock...thanks for your reply...larry

 

Moroso pan gasket (93104) I see people are giving great reviews...little expensive but worth it to eliminate any leaks...it is a rubber gasket 3/16 th's thick...Will give a review for the Moroso gasket once i install this week...

 

I'll have to let you know after I drive it for the first time. Haven't driven the car since the converter was installed. Need to do the cam break-in (which should be SOON). Of course that has me nervous...

 

If you use the Cork & Rubber gasket. Tighten the bolts "one" time to 65 - 70 inch pounds. With the Duraprene gasket (FarPak) the same. Make sure the gasket surfaces are clean and flat. DO NOT use any sealer on them. If you them this way, you will not have any leaks from the gasket.

 

Night and day at the drag strip. While we have several Yank convertors in the fleet, they get a littel pricey. On the other hand, the TCI 10" (both the "Streetfighter" and "Super Streetfighter") have proven excellent and economical choices. Having the lockup function is also very nice.

I find this is especially true with respect to the pan itself. I never could get the old and beat up pan straight enough or hold that straightness once torqued. New transmission rebuild also meant a nice new pan. Never had a leak again. FWIW, I prefer the Duraprene gasket.

 

Thanks Pro built...2 Irocs
