Nice truck!
Our 86, similar leak.
JB weld did the trick (mostly) it still looses a couple drips per week or month.
Clean all the rtv off, pinpoint where it’s leaking. Drain fluid, clean the surface. JB the **** out of it!

Welcome, Looks like a great find. To fix the leak on the T/C your
going to have to pull it to do it right. Might as well rebuild it since
its going to come out anyway.You would be surprised to find out how
easy it is to rebuild. GL :cheers:

Haven't even had it a week and I spotted a T-case leak.
That seat is newer, 95-99 OBS split 60/40 bench. I'm sitting on an identical one in my crew cab.
Nice looking truck, sux about the leaks.

Welcome from Austria. Great looking truck. If it's not leaking it's empty.
