6th gear problem? so i instaleed 456 gears in my car and now i have to shift into 6 gear at about 135-140 with the 26" tires not the 28" i use at the track. and for track i set my rev up to 6600 and on the street withthe 26" set at 6200rpm
anyways my question is when i shifted into 6th gear one night at 135-140 it never grabbed. my clutch still chirps 3rd but when i went in to 6 my rpm like reved up super high and i had no 6th gear almost when i shifted i poped the clutch cause i was racing myself but does this make any sense or sound weird at all there really no other way i can discribe it....

When in 6th gear you are putting more stress on your clutch than any other gear. When your clutch starts to fail the first place it is going to slip is in 6th gear. When going down the highway in 6th gear cruising at 1800-2000rpm where ever your cruise RPM is croud the throttle to WOT and see if it slips then. It could have been telling you that you didn't need to be going that fast

If it only did it at the track, then it's the clutch like Jeremy mentioned. If you lost 5th and 6th full time, then you probably sheared the 5-6 cluster gear splines on the mainshaft. (5th and 6th are REALLY not made for any sort of WOT/power)
Did 6th gear return on the street, or do you not have 6th gear (and 5th?) still?

We have a customer who likes to run at ridiculous speeds for hundreds of miles across the wide open western states and he has stripped the splines off of 3 or 4 main shafts till he finally revealed what exactly he was doing with the car. He ended up making a bunch more power so we upgraded him to a TR6060 and he LOVES it.
