Hi everyone, rebuilt my c4 a few months ago using a lot of advise from this forum.Did some oiling mods, kolene steels, kevlar bands, pa servo, hughes full manual valve body etc.Was very carefull with clutch pack clearances and used the Haynes book as well as this forum for the build up. Has been working great on the street, but on my first pass up the strip yesterday, by the time i got to the end of the quartermile i had lost all forward gears. I still have reverse, but thats all. Still managed a 12 @110 though!! Any ideas greatfully received before i take the trans out. Thanks in advance.
