96 4l60e 4x4 leak.

96 Suburban 4x4. Its leaking right behind the pan, but up on the case, can't tell exactly where because of how dirty it is. But, its leaking line pressure, I checked the fluid diagram and in park, line pressure flows through that same area. So, I'm thinking the case is cracked. Is there a seal back there that would leak line presure I can't tell from the diagram.

If looking from the bottom, its like right behind the pan and straight up, looks almost dead middle..like maybe where the casting comes together??

well, since its a 4x4 the tail shaft goes into the transfer case, so it'd be the seal between the two, but this is way before that, and I can see the fluid shooting out of it right behind the pan. I really just don't think there's any seal there to leak. Thank you for the suggestion.

Yes, its def. shooting out with pressure. What do you think it is to require a new trans?

Thanks!

With presure you will need a case and O/H. Had a few back in those days with bad castings.

guess a lil' jb weld won't fix this mess huh?

I'll check it out. Would an epoxy fix a crack?

it is cracked.

are there different lengths for the 4x4 transmissions? Is a 4x4 s10 style truck's 4l60 the same length as a 4x4 1500?
