Rocky,
I just noticed this.
Redline MTL is 75W80
Redline MT-90 is 75W90

That was a recommendation from Gary Hall. I called him for the ZF part which he had at the time. He said to try this stuff first before I took the ZF apart.  I did and the issue disappeared.

There was only 32,000 miles on it at the time so it was difficult to concede that it was the second gear syncro.
