That switch to Amsoil made shifting smoother and reverse easier to engage. Although it still takes a bit of coaxing from time to time.
I was one of, if not the first, to switch mine to Amsoil Severe Gear.
Zeeper- did you do the rear diff too?
Yes I did both. I didn't have a service manual and didn't read about sealing the plug threads -- I actually used anti-seize compound on the rear diff plug threads because it was so hard to remove them.
No leaks, whatsoever, so I am not worried about it.
