Reinstalling the trans. pan
Reinstalling the trans. pan I just got a aluminum trans. pan with a nice drain plug so I can change the fluid somewhat regularly.
I just need to know, what do you guys use on this to seal it up? I know it came with a POS rubber gasket. But, I hate those things.
Last time I sealed a tranny up, I used Toyota Red transmission sealant. Worked like a charm. That **** is 30 Dollars a tube. I have black RTV of course and a new can of Right Stuff. < Are either one of these a good way to seal it up?

I have used the permatex ultra black and that **** is stout. Follow the directions as you have to go back and retorque after an hour or so. Rubber gaskets work fine if you install them dry and torque to the gasket spec. I believe mine was a max of 15 ft/pounds.

Rubber gaskets have been fine for me, it's the cork
ones that truly suck. A cast pan should have a good
planar sealing surface while the steel ones can be
warped by overtightening.

OMG please do not use silicone! I feel it is a last resort if you have a pan that must be used and it just will not seal! With a new pan there is absolutely no reason to use silicone! Vince Bielanksi
I always use sealant, not silicone. . . . But, I have it on hand and just wanted to check.

Silicone on a trans pan/gasket is a no no. That stuff will squish when compressed and get into the trans fluid. No bueno.

I use the black fiber gasket that comes in the ATP filter/gasket kit... the black fiber material expands when ATF wets it.
Do avoid using any kind of sealer/RTV/silicone, not a good idea for various reasons.

The GM service manual says 97 inlb (8 ftlb)... I just go snug (not tight) with a speed wrench or a short rachet, being careful to not squish the gasket out...
the bolts have to be snug enough to not come loose, and not tight enough to squash/damage the gasket.

98-108inlbs for the factory pan. Some of the aluminum ones will require additional torque. I would check with the vendor on that. Vince
