TransGo shift kit install...

Oooo doggies...what a puddle, this morning.
Grabbed a wrench and slid under. Them pan bolts were barely finger tight.
I knew a cork gasket would compress a bit after initial run...no big deal.
Just retorqued them.
I'm sure I'll have to do it again after the next run.
I had to last time I changed filter and fluid, so I expected it.
I figure if it aint marking it's territory, there's something wrong.

I never use cork gaskets; they always leak. If you cant get it to stop leaking after x amount of rounds of re-torquing the bolts, replace it with a composite gasket (dont use rubber gasket either, unless it is a bonded/moulded rubber gasket with a steel core.

Composite?
What kind of composite?

Ok...I'm not the mechanical whiz-bang kid I fancied meself to be...
After tightening, retightening and thrice-tightening them tranny pan bolts, the leaking continues.
Honestly, I laugh every time I see it. Ya just can't make this up.
I've lost count the number of GL1000 & 1100 engines I've split open and every one I put back and ran, never leaked...and that's a metal to metal fit w/ just a smear of rtv.
It is funny.

So anywho, I bopped out to Summit and prused the "demo" isle. Low and behold there on the shelf was a TH350 oil pan of a fancy design. Yep it followed me home. Now the only reason I nabbed it was becsuse the original was pretty badly rusted. And I got a new engine oil pan last fall. It will be going on when I pull the motor.

My 2¢, I’ve had very good luck with Lube Locker gaskets. They are a little pricier than a standard gasket, but they seal up good and are reusable.

I’ve got about 8 of their gaskets in service right now, the trans, front and rear diffs in the Cummins, trans and rear end in my 79, trans of my 76, a friends 9.5 semi float and the 9.25 front in his Cummins.

Those pans with the cooling fins work well, but are a pain in the ass to clean. All the clutch debris collects under those tubes where you can’t get to it.

As for the leak, there are lots of other places the fluid could be coming from. Look around the dipstick tube, the kickdown cable, modulator oring, accumulator cover, the list goes on.

Go to your nearest parts store, get a small bottle of A/C oil with the fluorescent dye. Add a bit to the fluid, take the truck for a drive. Then crawl under it with a blacklight. The fluorescent dye will glow, making it obvious where the leak is coming from.
