My 3500 dieseldodge

the transmission builds up pressure and the fluid goes in transfer case and leaks on everything have to drain it and put more fluid in why does it blow out of the seals they have been changed and i don’t no why it builds up pressure/

Stuck pressure regulator? How many miles on this? Time to tear it down.

theres no pressure regulator where did you come up with that idea transmission and transfer case were rebuilt within this year changed all the seals today we will see what happens

The transmission CASE must have a VENT that might be PLUGGED.

I checked that and both vents are open that’s why I can’t figure whats wrong with it.

“where did you come up with that idea”

I was thinking automatic trans.

nope it’s a 5 speed
