i was on the freeway today and whenever i hit the accelerator it was as if i had the clutch in. It just reved and reved!!! the only gear that halfway worked was 1st but that only worked up to about 1500 rpm.
I just had my cluth master cylinder replaced so im hoping that it was just faulty repair work.
Is there anything else that it could be?

thanks a lot,

sounds like the clutch is slipping. how many miles on the truck and the clutch.. Or a rear mail seal leaking on the clutch.

125K on the truck... and the clutch was replaced last summer in july. so it cant have more then 8-9K on it at the most.

if the clutch is infact slipping what do i do?

yea it shifts no problem, and the clutch feels fine.

Possibly the throwout bearing. The only thing I can guess is the clutch is no longer engaging the flywheel. Might need a new throwout bearing when we swap the tranny, but I bet the new tranny will come with a new one also.

just for the hell of it, does it do it when you have the diff locked also?

You might make sure the slave rod is adjusted properly. Sounds like it may be too long and doesn't allow the fork to return far enough to allow the pressure plate to fully 'pinch' the disk. Plus it follows the "last part touched" methodology. Worth a look. Good luck.

so miraculously the 90 seems to have fixed itself, for the time being at least. I just fiddled around with the Tcase and everything is now fine ( knock on wood)
but knowing my truck, the problem will come back very soon.
dave, i thought it could have been the throw out bearing as well but i remember last time it went out there was a horrible squeeling noise whenever the clutch was engaged.
Tom i will be sure to check out the rod when i have the tranny dropped next month

thanks to all for the advice!

If a MC or SC is misadjusted they will build pressure and disengage the clutch.

Make sure there is the correct amount of free play on the MC pedal, I want to say it is 1/2in-3/4in but IIRC it is in metric and I do not do metric.
