turbotrana Member 2,586 Member For: 22y 1m 17d Gender: Male Posted 23/04/08 03:18 AM Share Posted 23/04/08 03:18 AM They are a very strong box if you make them shift harder, and there are a couple of tricks in doing this. You can do it via the S5 solenoid which is OK for mild power levels but there is another step where you eliminate the S5 function altogether and gives maximum shifting hardness. And it doesnt snap input shafts like the ZF does.
