Thread: Trans Pan Sealing

Tweet

Been looking at threads on Trans Pan sealing. Using gaskets vice not using gaskets. Many people have issues with leaks especially with chrome pans.
Any inputs ?
"lt1s10" and "DennyW"......?
Any help will be greatly appreciated.


P.S. It was "cook67" who said to use white foot powder on a suspected leak. NOT "lt1s10".

If you go with a crome pan take some 80 grit sand paper and a little spray adhesive lay it on a good flat table and sand the mounting surface. Don't go to far into the crome you just want to rough the surface up. This give the gasket and or sealer something to bite on . I did this to my diff covers and no leaks, if you have the room I'd go with a larger aluminum pan.

no i dont use foot powder. back when the th400 first came out the pans would bend, crack and everything else after you pulled them off a few times, so if you want a no leak pan, strighten the pan up, clean everything , glue the gasket to the trans. (yellow snot) and then run a small bead of sealer(black) on top of the gasket and tighten the pan down, and hope you are not the next one to have to pull it off. the snot will seal the top and hold the gasket in place and the sealer will fill the cracks, and around the bolt holes. dont over tighten.

"Yellow Snot"
The local NAPA probably won't know that nomenclature.

Care to clear that up ?
Who makes it?
Name, etc.
Thanks

yellow snot 3 m gaskets cement used in the auto body field works great i use it all the time on gaskets the only thing that is better than this is omc gasket cement you have to get this at a boat yard. this stuff is killer use this stuff to hold the oil pan gaskets up when i worked at the boat yard and i did rear main seal jobs with the engine over head on the chain fall this stuff is much better i do not know if you can get it still but i think some one that work at a boat yard can get it OMC made it i think it was typ m ??

its made by 3m and you want the yellow and napa will know what yellow or Gorilla snot is. its been around for ever.

Wow.
Thats why I didnt understand what you were saying.
In my minds eye I'm thinking some type of RTV or sealant.
So:
3M 08008 on the tranny.
3M 08001 on the transpan
Gasket in between both.
Right?

this is the way i do this omc type m or 3m yellow panside with gasket to trans side not to much rtv on trans side if you do both side with omc or yellow 3m it will take a hammer and a pry bar to get the pan off i not kidding

either way will work, dont put to much yellow, lay a bead of yellow on pan or trans. put gasket in place, pick it back up and then put it back in place. give it a few min to dry or it will slid off of the pan. like pat said dont use it on both sides or you will have a hard time getting it off. it has to be clean and dry. this is what you use on valve cover gaskets and front and rear intake gaskets. you cant knock the rear intake gasket off if you do it right. the yellow is not for sealing, but to hold the gasket in place.

Okay. I went out and bought 08001 and 08008 as instructed.
