68RFE front pump seal leak?

[TSandner]

I have a 2008 2500 4X4 with 324,000 miles. When I park facing downhill, the transmission leaks from the front. The truck runs and shifts great, itj's just when parked, shut down, and facing downhill. Is that going to be just the front seal?

Hose it off clean then look to see where any new damp oil leaks are starting

There's no question it's coming from the front end of the transmission, dripping from the bottom of the bellhousing. The odd part is it only leaks when shut down parked in a nose low attitude.

If you clean it, you will be able to see if it is coming from internal (inside the bell housing) or external like the sump pan, vent line, fill tube, or some other exterior penetration to the case. Either location can drip from the front of the transmission when nose down hence the recommendation to wash and check for source. If Internal, could be the seal, pump, TC, TC drain..,,, just to rattle off a few.

FWIW.. My 04 leaked engine oil from the back of the pan, thought it was a rear main, when I pulled for a clutch it was dry, turned out it was the front cover by the crank sensor running down the edge of the block, then around the corner and down the pan...

Point is it can be tricky to nail down the source of a leak, especially an intermittent one,. JM2C
