is there an alternative? like weight that i can buy at a local auto parts store?
cuz i really dont have time to go to the dealership right now
i heard 75W 90 but i'm not sure

help pleease

75w90 is fine ***syncro, be sure its compatable with syncros....

Only use fluid from the dealer. The nvt-350 trannies have syncros that can get messed up if you use any other fluid. This is info I found out when changing mine. Some people use aftermarket oil and dont have problems but Im not willing to try it.
