Hi, my name is Evan. I bought this car with 112,000 miles on it. The clutch slipped so I got it cheaper. It slipped intermittently. It would slip for about a weeks period, then for about one day it would lock up fully. I replaced the slave cylinder and bled it completely. It still slipped intermittently. So I had the release bearing, disc and pressure plate replaced proffessionally with a new engine as well. It still slipped intermittently. The mechanic SAID he resufaced the flywheel. But I dont believe him. So I replaced the master cylinder and bled it again, this time bleeding an entire 2 bottles of CLEAN brake fluid through. Meaning after I bled all the dirty fluid out, I continued bleeding. It was so clear that I thought it looked like air coming out of the bleeder valve. This worked for about 3 days, then it started slipping again. This was about 6 months ago. It still hooks up about one day every couple of weeks. Do you think air is gettting into the system still? Can a few air bubbles cause it to slip or can a worn flywheel cause intermittent slips? Tranny problem? Im extremely confused please help! Thanks, Evan

Hi there,

Air in the hydraulics will not make the clutch slip. That will only cause a problem releasing the clutch (not enough hydraulic pressure ) I would be looking at the clutch assembly and in particular the clutch fork pivot pin. Check the fly wheel for hot spots and heat cracks, check min thickness of the fly wheel and use only genuine Toyota clutch components, as some after market clutches are not very compatible.
