Tranny fluid from differential or pan

[mark raudenbush]

Okay so how many of these discussions begin with "I just took my RV out of extended storage"

She's been put up for a year. I started it up today and I have tranny fluid dripping from right between the pan and the differential. Anyone seen this
before? I'd love to think it's just a pan gasket, but could it be the rear (front) seal?

Thanks
Mark

If it's pink, it's transmission fluid. If it's brown, it is differential
lube. If it's leaking at the joint between the transmission and final
drive, then it probably the duplex seal. If that is the case, the final
drive or the transmission needs to come out. Sorry.

Is it coming from the weeping hole?
Call me so I can guide you.

It is pink, certainly tranny fluid. I had the tranny rebuilt in key West a couple years ago, I was surprised to see problems at all.

Not looking forward to dropping the tranny again.

It doesn't seem to be out of the weep hole. There's a bit of a bulge in the pan gasket I'm hoping it's just that

Jim, I'll call you some time this week see if we can identify the problem.

Much thanks
Mark
