when my car is running and I have the clutch pedal to the floor its still grinding gears.... But when I had my friend pump the clutch while I watched the slave it is moveing and doing its job... Now I have no idea how much travel the slave has but it looks like its extending about an inch....why am I grinding gears??? I can get it gear but I gotta slam it but once its in there is no problems and the car still idles fine so I dont think the clutch is screwed...

Any ideas would be appreciated!

about 1.5" then it starts to get stiff for the next 4"

I'm thinking my pressure plate may have some broken fingers and its crooked when I enguage the clutch causeing it to lightly touch the disk... I dont know whats wrong I just know it still clamps like a son of a bitch ( couldnt get it to slip if I tried)

I just drove the car to work and had no problems shifting.... Damn this is confuseing... Ive blown several clutches in my short time but this doesn't feel like a warn clutch...ive also had a master cylinder go on me but I dont think that's it but again I'm new to supras...

My new transmission is on its way but I need to figure out what this is so I can get every thing ready to swap...

ok cool... It just started doing this today... Spent all morning in the car running around then when I went home to change clothes and got back in the car it just started grinding reverse gear...but yeah I'll adjust the play out if I can and see what happens.... Thanks IJ!

Oh and who should I get a clutch from....horsepowerfreaks are a little on the pricey side!

Ps... No out of the norm noises... Only noise I hear is the blow bearing in the tail houseing...

No probs.

Reverse is always going to be a bit grindy, when yout trans is in neutral with the clutch out idling doe it make noise? (foot on the clutch noise goes away?)

I had a good run with ACT clutches when I have my w58 not sure who has the best prices I'd just hit up a few of our vendors here and see what they can do.

nope no noise at all... Can't even hear the throwout bearing when it contacts the fingers! Nothing is out of the norm other then the grinding.... Now I know reverse will always grind a little but this is kind of extream... It grinds pretty bad and doesn't want to slip into gear so I have to jam it in and it grinds and pings but once its in gear all is well! Engine rpms dont flinch at all.

Was just asking as w58's have a bad habit of eating the hardening off the nose of the mainshaft, this allows the Input shaft to wobble around and cause the issue you're describing.

When you go for reverse nudge the shifter towards a forward gear for a sec this should stall the mainshaft and reduce the grinding and allow reverse to engage.
