Sealing a transmission pan

Alex Kurdian · Post by **Alex Kurdian** » Tue Oct 20, 2009 6:14 pm

Hi All

This is how good chrysler are down here...twice I have had to take my car back to chrysler to drop and reseal the auto trans pan...they "Glue" or "Apoxy" the pan

THey put this on and it never goes on as a proper seal so...low and behold its leaking again...I have to take it back a 3rd time for them to re fill and reseal my transmission...

IS it really that HARD? FARKING deadbeats!

It shouldn't leak like that while using RTV. They may not be getting all the old stuff off before they try to seal it back up.

i changed my tranny fluid not too long ago and there was a shitload of extra sealant. it didnt leak but it made my job that much harder.

That or they just really suck at applying it properly.

1 - OIL PAN
2 - 1/8 INCH BEAD OF MOPAR® ATF RTV (MS-GF41)
3 - OIL FILTER

Is it always leaking in the same spot?

Alex Kurdian · Post by **Alex Kurdian** » Tue Oct 20, 2009 6:31 pm

that looks easy enuf I guess the drop kicks are just born useless!

Yes its always the same spot the rear of the pan not the front or sides...

hmmmmmmmmmmmm, could this be a result of stripped bolts?

Alex Kurdian · Post by **Alex Kurdian** » Tue Oct 20, 2009 6:40 pm

if they have stripped the bolts how do I fix it?

The bitch is getting it clean enough. They are prolly rushing it. The fluid will drain for hours, constantly going over the sealing surface. You have to spray some fast evaporating solvent onto the general area, wipe clean, and slap the pre RTV'd pan in place, before it drips again.

The best way is to let it set overnight, with absobent rags in a loosely installed pan. Then drop the pan, RTV, clean the pan rail, and install the pan. But most of us don't have that much time.

RTV is idiot proof, WHEN APPLIED TO AN APPROPRIATELY CLEAN SURFACE. Most idiots forget the second part.

I used some cork gasket at NAPA. I don't have any leakage.

Knock on wood

over time, the cork gasket will let fluid by. mopar atv sealant = FTW. im on my second transmission fluid change and i have never had any leaks. they must be rushing and not cleaning the pan properly.

I just put the gasket on that came with my filter and it's been fine.....shrugs. The gasket isn't cork though, I think it's a rubber one.

I've always had leaking problems with this tranny. I'm tempted to have it welded and tap it with a drain bolt. haha that would be cool but I doubt it would ever get all of it out...

Adionik · Post by **Adionik** » Mon Dec 07, 2009 6:15 pm

Yep, new tranny is leaking like a son of a bitch.

I think I messed up because I applied RTV, then put in the fluid. I should've let the RTV cure overnight...then put it in later the next day.

...That's a really great idea... you could drill the hole on the lowest spot on the transmission, but put it to the front or back and when draining it the fluid, park on a hill... it could work.

sorry to hear you're still having transmission issues. readysetswap.

You wouldn't want to tap the pan. You would want to get one of those little drain plug kits.

Welding would be a bad idea, because if you messed it up you would have a bitch of a time correcting it without a new trans.

once you apply the RTv sealant (sp?), wait 10-15 mins, then re-install your pan. don't wait overnight or the sealant will dry up.

RTV silicone never dries up, it just cures

.

I think he meant he put the pan on, then added the fluid before the RTV cured to any extent.

The bitch is, the damn fluid never stops dripping. The best way I found is to spray it down with brake clean, after scraping the old silicone off. (Both Pan and ATX) Dry it with a lint free rag. Apply RTV silicone to the pan before spraying/wiping ATX. As soon as ATX is clean/dry, slap the pan in place, then put screws in but only tighten enough to push the RTV out a little. Let it cure for 15 to 30 minutes. Finish snugging the screws. Add fluid.

That's what I was considering doing. Spraying it down with brake clean, cleaning it all off and then applying RTV and letting it dry over night before adding fluid.

Right now I found a few loose bolts that i'm hoping is the problem for my leak. I also added RTV to a bolt that seems to be stripped out. Fuck. I'll post back what happens. I literally leaked out an entire quart at work.

Okay wow. Leak is STILL happening. I thought I fixed it. Fucking car is cursed from this transmission.

Alex Kurdian · Post by **Alex Kurdian** » Tue Apr 13, 2010 11:48 pm

Tell me about it ever since the stealership TOUCHED my transmissions its all gone all messy I'm taking it down next week to have the pan RE-SEALED ! For thr 3rd time....

I said to them take it off clean it up re seal it and leave it there over night...then put the trans oil in ...the friggin thing prolly doesn't cure proper....

They are friggin useless parasites!

No offense to good mechanics out there...

yeah i feel ya man, i had the mrs take hers into the shop for a fluid and filter change. Of course they screwed it up and i had to redo it myself in the dead of winter. I took my good ole time and scraped all the old sealant off with a razor and wiped everything down with cleaner. Put down a nice bead of rtv and torqued the pan to spec, not a drip has leaked since. want it done right, just do it yourself

darthroush · Post by **darthroush** » Wed Apr 14, 2010 3:38 am

The Dodge dealership here told me the ATF RTV doesn't need a cure time. Just bolt it up and go?

r/tguy02 · Post by **r/tguy02** » Wed Apr 14, 2010 7:12 am

it does take time to cure, but you can still bolt it right up and fill it with fluid, it wont leak.

darthroush · Post by **darthroush** » Wed Apr 14, 2010 12:45 pm

Well, yeah. Thanks for the correction on wording.
