Transmission Case Leak, Transmission Case Leak Options

[engine247]

Howdy,

I noticed a newish leak under the car. So I clean up the bottom best I could and let it sit for a bit. The leak appears to just seep through the case slowly but consistently. Maybe a defect or small crack? I'm wondering what my options are here? Only solved with a new case or is there a band aid until this can be bundled with other related maintenance?

Cheers.

@rjames I hear what you are saying so I've double checked again. I can wipe it all down and actually watch the next drop form. It's like digging a hole in the sand and watching water fill it in. The exact spot has a bit of a different texture if I run my finger over it. As for the ring area you highlighted can the case just be that porous and is saturated with gear oil?

I'll give the jb weld a shot but not sure how well it will work as the drip re-forms so fast that I doubt I can get it clean and dry long enough for the jb to set up.

I think if you want to seal it with JB and it is forming that fast...

Pull the trans out (you can do it with engine still in car.
Drain it.
Turn it upside down and let anything inside drip away from that surface.
Superclean it in the method of your choice.
Texture it with something abrasive so the JB will stick and go to town.

Short of that, you are wasting your time.

Alternative: Empty trans and jack the car up so anything in that area would drip away from it for a day or two. Superclean, texture, and JB.

That might work.

Let us know how you do it and if it works. It is always interesting to learn from someone else's woes. We all have them.
