Hey I picked up a hydro GSR tranny unkown year. Everyone has always told be as long as its a hydro tranny year to year its the same parts. I just purchased 2-4 complete gears for a ('96) GSR tranny, both main shaft and counter shaft from acura, as well as 1-5 carbon coated synchros ( Gear-speed ) . My PROBLEM is the 3&4 gear sleeve set on the main shaft is too big for the fork. Is there a difference in hydro GSR tranny parts from year to year?
