Thanks all for your inputs. I have been running Mobil 1 synthetic 15-50 in my trannys but now think I will go even lighter to say, 0-40. Anybody know what the weight numbers would be for ATF?

The tranny I am working on has been sitting for years, so moisture may well be the reason for the pitting.

Jerry, thanks for the LSD additive p/n. I will get some and check it out. Can you tell me if it will affect the shift quality?

Another question. Why do the replacement bearings come with either a seal or a shield? I would think that a free flow of oil over and thru these bearings would be the the best deal.

Zack, I like the 'million year' number. So far,I have been able to get only 100k +/- out of the Isuzu bearings. The gears are always good unless driven too long on bad bearings.

Regards--

Paul
