[KTL]

The synchros can go for years and years w/out rebuilding, even if crunchy. They're not like the 915 which can eventually let go of the synchro pieces that then cau$e collateral damage to your tran$

Mine has 83K on it and has been crunchy going into 2nd when cold for a long long time. Usually takes only a few shifts for it to get better. I've tried all sorts of gear oils and none have struck me as being leaps and bounds better than the others. Mobil 1 from local parts store, Mobil 1 SHC/Delvac, Redline, Swepco, Valvoline HP dino. All seem about the same to me. I currently use the Valvoline in the white bottle and it works fine.

I noticed in the past few years of track driving that the 3rd gear upshift and 2nd gear downshift would crunch as the temps got hot. The way I "fixed" that is to double-clutch on the downshifts and be more patient/gentle on the 3rd upshift.
