I'm using the wrong tranny oil!! I called to order a rebuild kit from Gearzone.com, I called, and the guy on the other end (Paul), was very helpful. I explained that 2nd gear grinds sometime, and he was saying that most boxes fail due to lack of lube.

I then mentioned I believe that's what happened to mine in it's past life, because I had to replace the input shaft bearing. But now I keep it topped off with 80W90 like my Haynes manual recommended. He said "You're running the wrong lube". I was amazed because I even had a shop check the lube on it, and they said nothing about having the wrong lube. He even asked me if I wanted to hold off on my order until until I try Mobil-1 ATF synthetic like he recommended.

Even if it doesn't work with the new lube, I appreciate a shop that was more willing to help a person rather than just take thier money..

I was impressed, and I highly recommend them!

I also posted this in the tranny board...

 

glad your happy!

 

UPDATE: I drained all the 80W90 out, refilled with Dextron2, and it shifts like a champ now.

Don't believe everything your Haynes manuals tell you....
