Well I got the stuff in there and so far no leaks seen after a good hose down of brakleen to clear the layers off.
What I did find was also another suspicion. The rear main is leaking very bad. Which may be the oil culprit but the coolant loss of course rules that out.
Question is, How bad can a rear main leak?
Reason being was after cleaning everything off last night a 20 mile trek was enough to produce drips of oil coming out of the trans inspection cover.
I'm thinking this may be my oil down the side of the truck and trailer culprit from last weekend.
Sad thing is, I'm gonna have to either pull the motor or cut the crossover pipe to get the trans back far enough to get back in there.
