RE: [DML] Automatic transmission pan gasket leak fix?





I too have a trans leak, (I was the guy 2 years ago leaking all over the parking lot at the hotel at Indianapolis, but I wasn’t going to miss that!)

 

I had to take my pan off to remove the computer harness.  When I put it back on with a new gasket, it leaked really really bad.  I took it off, removed the gasket, “pounded down flat” the dimples I had created by tightening the gasket too tight, and reinstalled this time with some gasket goo.

 

Still leaks a little bit, about the same as yours.  I need to get under it again and pay much more attention to the install (I could have the tranny computer o-ring leaking also, need to check).

 

The original gaskets had a copper crush washer in the bolt holes.  This prevented you from overtightening the gasket and squishing it out.  The gasket I had originally removed had those rings, but the replacements do not.  I’ve wondered about using Fuel line copper gaskets and manually cutting them into a new gasket (like the factory) if that would help.  Anyone ever done that?

 

I think the torque specs (other than “Tight, but not too tight”) are for the gaskets with the crush washers.  Anyone have a torque spec for a gasket without a crush washer?

 

Tight, but not too tight?

Subject: [DML] Automatic transmission pan gasket leak fix?

 

 

I have a slight automatic transmission fluid leak around the cork gasket that is sandwiched between the transmission fluid pan and the transmission itself. I imagine it's a result of some imperfections in the pan mating surface, but the overall effect is the gasket looks saturated and any wires or structures that happen to brush up against the pan side end up wicking off this fluid, which then slowly drips on the ground. The leak is very slow, a drop or so an hour. The thing is, this eventually leads to me having to put more tranny fluid in to keep it topped off.

 

When doing transmission work in the past, I cleaned both mating surfaces, installed a new cork gasket, and torqued the bolts to spec. So it's not a situation where the gasket is old. I've got another cork gasket I'm thinking of installing to stop the leak, but before I do I wanted to get the insight and experience from those here on the group. I was planning on using regular blue RTV this time around on both sides of the gasket before installing. Would this be a good approach? Anyone have a similar experience and approached it from a different path? Anyone with a different recommendation because they had to drop the pan at a future date and found a better solution?

 

Thanks for your help!
