Thanks, I'll try that.
This is my first project and I have a lot to learn.
Apparently things have come a long way since plain old 90w.
A while back I posted about the leak in the back of this tranny and was going to drill
out what I thought was a frost plug. Was advised that it was a shaft not a frost plug.
I got it cleaned well and sealed with Permatex and that solved the problem. That
advice saved me from ruining the transmission.
