Another tranny question
From : scott
Q: i have a 2000 durango. i just changed the tranny filters last night and buttoned it all up. this morning i found a real small puddle under the tranny and looking at the tranny i can see fluid. i tightened the bolts in that area a little more not much. when i get home tonight and it still seems to be leaking a little does this mean i need to take the cover back off and redo the permatek gasket again. thanks for your advice. scott .

thats me wrote quoted from my fsm dr automatic transmission - 45rfe/545rfe 21 - 509 ===========8--snipped--8=============== 53 apply rtv silicone to the oil pan and install the transmission oil pan. tighten the bolts to 12 nm 105 in.lbs.. ===========8--snipped--8=============== the two other transmissions inn the fsm call for gaskets. so apparently this is not your grandfathers transmission and i dont think the word apply means to slather the sealant on like your frosting a cake either. a small 1/16 inch bead along the bolt line is most likely enough. learn something every day .................... jerry .

gotta be reeeal careful with that stuff. if you use too much it will ooze out into the pan when you tighten the bolts. use your imagination as to what happens next. ummm.... it floats around the pan and worst case sticks on the bottom of the filter screen unless you use the whole tube there wont be nearly enough to plug the screen. .

yep thats what is called for. i was a little surprised also. the service manual said this in the fsms i have they all call for a replacement gasket to be used supplied by mopar. no sticky stuff. bingo permatex is a bad thing if it gets in trans vbs and such. max life liberty and the pursuit of any jackass that threatens it. embellished usnavy slogan .

if i were you i would drop the pan in a hurry and get that stuff removed. get the proper gasket and use a little grease to hold it in place for installation if needed. grease on a gasket that you want to hold still permatex has an anaerobic sealer that used sparingly will hold a gasket wont go all over the place isnt slippery and wont let a gasket squeeze out of place. max life liberty and the pursuit of any jackass that threatens it. embellished usnavy slogan .

if the op used old permatex blue its going to leak....period. so atf is worse on permatex than gl-5 chrysler has been using rtv to seal the transmission oil pans and extention adapters on the 45rfe transmissions since jusly of 1998. in using any sealant on the oil pan you must make sure that it is atf compatable and apply a small continuous bead around the inside of all bolt holes in the pan. i dont know if the permatex blue is atf compatable. .
From : scott
well it seems that the leak has stoped. i went under and checked the bolts. found out i missed one. i mean it was on there but not tight. stupid me. seems to have fixed the problem. and the permatex that i used was the black kind. i dont have it in front of me to give the specific model number of it but it was black. thanks everyone for all of the info. and i do have the 45rfe which had rtv on it which i had to scrape off. out of everything taking the pan and dealing with all of the atf draining out i would say scraping off of the rtv sealant was the worse part about it. scott if the op used old permatex blue its going to leak....period. so atf is worse on permatex than gl-5 chrysler has been using rtv to seal the transmission oil pans and extention adapters on the 45rfe transmissions since jusly of 1998. in using any sealant on the oil pan you must make sure that it is atf compatable and apply a small continuous bead around the inside of all bolt holes in the pan. i dont know if the permatex blue is atf compatable. .

yep thats what is called for. i was a little surprised also. maybe its another way to get people to take their stuff into a full time mechanic instead of doing it in your driveway. but i will try to fix darn near anything if i think i can. partly because im cheap and partly because i find it very interesting. permatex gasket on a tranny pan hmmm..... .

the service manual said this in the fsms i have they all call for a replacement gasket to be used supplied by mopar. no sticky stuff. i find the permatex thing real interesting also. mopar even has a grometed gasket available that is real slick and needs no sticky stuff as if a regular one needs it either but then again ive found engines with silicone all over the head gaskets and the head bolts just past finger tight politics the gentle art of getting votes from the poor and campaign funds from the rich. .

out of everything taking the pan and dealing with all of the atf draining out i would say scraping off of the rtv sealant was the worse part about it. dont use a scraper use a utility knife to cut the beads of it off .
From : scott
thanks for the tip. dont use a scraper use a utility knife to cut the beads of it off .
From : transurgeon
you dont have to get the pan or rails clean all you bneed to do is get the excess beads off..........where the rtv has been flattened between the pan and rail leave it alone and put a very small bead on top of it thanks for the tip. dont use a scraper use a utility knife to cut the beads of it off .
