hi! all
this is second post ( did first one on ram van )
this site is great i am happy to have login name and pw
ok i changed atf for 99 gc 3.3l around 4 month ago, (first time by myself ,did mistakes as beginner or amateur like overfill or handling silicone for trany pan)

and 2 weeks ago trany was licking a lot so i change gasket ( not filter) , add 4.5 qt ( i think proper amount for my trany).

to be surprised, it is licking again today.

i did again today. this time is differrent, i use chilton repair book, it say using silicone (sealant, whatever..) on trany pan when install

i think that is problem this time i use only gasket

putting silicone ( sealant)on pan make just mess on pan and my hand

it is not licking ( i'm not on road yet)

i hope not and i hope my decision save money ( next time same thing happen i'will take it to expert guy)

 

I personally try to avoid using silicone try torquing the bolts to spec and see if that helps

 

Using silicone is standard practice, it seems, for the transmission pan.
Perhaps your solenoid pack is leaking - not an uncommon problem.

 

Here are some mopar part numbers for the reuseable pan gaskets.

Thats if you don't want to use silicone. Always clean out the bolt holes if you are using silicone. Or you could crack the case.

 

after using RTV a typical place for it to leak is at the back of the pat toward the diff. the reason is the diff still holds fluid and will continue to drip even though you wipe it off. a trick to do is to make sure the metal as NO atf on it. i usually blow shop air into the diff portion to blow the fluid out. i've also seen guys use a small piece of brake line that is curved in a candy cane shape to alow gravity to siphon the fluid out. hope that helps

 

thank guys for your input

so far no leaks

but i can not guaranteed for long trip

i know mopar reusable gasket but it is around $60

next time i better try that one

 

It depends on the trany pan's gasket, on whether to use silicon sealant on gasket. Some gaskets arefabricated and some are a rubber material. If you are using the one that is rubber material, do not use silicon sealant on it; instead, use a thin layerof trany fluid (just like as you would do with an oil filter - putting a thin coat of oil around the seal).
