The seal needs to be replaced. Everything shrinks when its cold. When it heats up, it expands. Yours is just worn enough it leaks.


I think there is a seal there.

I don't feel like working on anything at this time so i sold my yj.

That's a common leak point for those transmissions. I have been told you can replace that seal inside the vehicle by removing the valve body but other people have said that's not a good way to do it.

You can go on for a while, until it gets too messy. In my case, since I use it as a daily driver and occasional road trip vehicle, I decided to have it dropped and had it rebuilt all around (rather than waiting for it to fail). It cost a bit, but in those transmissions can last forever if you keep them up.

Yup, very hardy transmissions. I never had a bit of trouble out of mine and it was behind a stroker
