I recently changed from regular gear oil to Royal Purple synthetic grear oil in my diff and tranny, and it seems much notchier when shifting, as if the syncrhos are not working as well as before. The bottle said it contained an additive for LSD (limited slip differentials). Since these additives reduce friction between non-metallic surfaces such as diff clutch plates, can they also negatively impact the way the transmission synchros work?
