i have a ram powergrip hd clutch, shifts fine under 5500 but when i race it and get on it cant shift over 5500 i can shift over 5500 but must shift very slow. seems lilke its not disengaging all the way and feels like hitting a wall for every gear when shifting fast,have stock hydralics .thanks

very good read.

have you tried bleeding and doing the drill mod?

 

yea i bled it i had the drill mod on my old master/slave and it did the same thing but it was leaking,now i got the knew master/slave but no drill mod and not leaking and still it does the same thing do u think i should do the drill mod on the knew master/slave.since this one is not loosing fluiid pressure

 

yes, the drill mod is imortant for shifts at 5800+

 

i just did the drill mod today and still having the same problem i dont know what else to do maybe shim the clutch
