i have noticed a difference with BG syncroshift, in my awd's. used to run castrol sytech gear oil. Back to the original post, very good info, seems about right to me. and yes the 2nd gear double snycro trannies are stronger, but not in all areas just a few things are stonger otherwise there the same. just did my 4th rebuild for a beater awd i got, and alot of the stuff is the same. if anyone needs any tips i have learned what to do and not to do when building one. the 93 one i build for my good car i beat the crap out of. not problems, just make sure to do the shaft/bearing preload correctly, otherwise quick shifting sucks, maybe ok for the normal driver though...
