I have tried to replace this gasket 4 times now. I have a brand new pan, and
I always torque to 8-10 foot pounds.
From the looks of it, it leaks down the bolts somehow. I always see the oil
welling up on a couple of bolts.
I have tried rubber, cork, and fiber composite gaskets. I never use rtv or
any sealant as it is not recommended, but I am about ready to put some on
out of desperation, just have to be careful not to let it squeeze out to the
inside of the pan.
It is not a huge leak, but it frustrates the hell out of me that I cannot
seem to stop a simple leak, and I am tired of seeing that oil on my garage
floor. And it is only ten bucks for a new gasket so every couple of weeks
I'll try again, and I'll probably be trying again this weekend too.
If anyone has experience with this give me a clue.
Too much torque. You're smashing the gasket.
60-65 inch pounds is more like it.
If you're using a 3/8 drive torque wrench, you don't have the
accuracy needed at the lower range of the scale, get an inch
pound torque wrench.
He's either got a Chrome pan.........
or the bolt holes are PUCKERED...(i doubt that one)......
or the leak IS NOT a pan gasket leak.
there ......i said it.......now i feel better.
~takes a sip of his crownroyal..........mmmmmm...good stuff~
It is entirely possible that when the Chinaman punched this pan he was
worrying about his tea ration being cut back if he didn't punch out
5000 that day.It wasn't done right and there is a flaw.
I would check it carefully with a straight-edge over each hole and
look for any splits.
Look above the leak area for a higher leak (already mentioned in
thread),and if it still leaks with the correct torque which BTW is 12
(TWELVE) Ft. Lbs.according to the GMC shop manual in front of me,then
Wow, nice to see the passion guys LOL!!!
Well it IS a chrome pan, Marsh Monster mentioned that. And the holes aint
I have a Haynes manual and it says 10, I do have a inch pound wrench and I
get it to 120 inch pounds actually. I have never gone crazy on it and tried
to torque it down to 30 foot pounds.
If I seal it up and fill it up, it does not leak. If I go for a drive, get
the fluid hot, check the fluid level to make sure it is just right then park
it, it still does not appear to leak for quite some time.
But the next morning... %&$*ing leaks.
I figure if it were a leak somewhere else it would be evident soon after
driving and bringing it up to temp then parking it, but it waits about 6 to
Thanks for the info.
Clean the pan and all around the transmission real well. Then clean the
pan and gasket surface real well and install a new gasket with a bit of
high tac on it. Torque it down and then fill it up with fluid. Now take
some baby powder and dust around the gasket and around any seal point
(TV cable, shift shaft, dip stick tube and such). Then take it for a
drive and see where the powder gets damp. That will tell you where the
leak is. Once your done just take it through a car wash and clean it up.
T'was me, I'd take a grinding disc and remove that fancy chrome stuff
from the sealing surface of the pan. No amount of sealer will seal a
chrome tranny pan.
Yo! Marshie...pass the shroom juice. :-)
