Johnny176 Posted May 25, 2015 Share Posted May 25, 2015 Hi Guys, I have a supra with a v160 box, a new stage 2+ Spec clutch and an OEM flywheel. When cruising about at or below 2500rpm I can select gears with no problem, if I was to rev to limiter and then try to change I need to force it into the next gear and it will always take close to 2 seconds before it will go. It doesn't crunch or sound unhealthy but it doesn't like high rpm changes. If I am sitting parked with engine running it will click into gear with no issues except for reverse. It will always need forced unless the car is off. When I'm on the bite (when I can find it) there is no shuddering or shaking, everything seems smooth and normal until I try to change gear at high rpm. I have checked the clutch is bled properly and fully disengaging by jacking rear up with engine running and putting in 1st with clutch in, the wheels didn't turn until I lifted pedal about 1/2 an inch. Anyone seen this before or can suggest something to check? Thanks, Johnny Link to comment Share on other sites More sharing options...
Pig Posted May 25, 2015 Share Posted May 25, 2015 I have a Spec 2+ Clutch and had similar problems which has resulted in loosing 2 gears. My warning to you is to get it sorted before you lose your box. Best starting point would be to bin the clutch IMO. Link to comment Share on other sites More sharing options...
MKIV-Supra Posted May 25, 2015 Share Posted May 25, 2015 Maybe the way from the cylindre isnt long enough to clutch 100%? Link to comment Share on other sites More sharing options...
Johnny176 Posted May 25, 2015 Author Share Posted May 25, 2015 Serious Pig?! What did you do to resolve it or did you just get a new clutch? MKIV-Supra - I was thinking that initially as well thats why I tried jacking the back of the car up, if it wasn't out 100% the wheels would still turn Link to comment Share on other sites More sharing options...
MKIV-Supra Posted May 25, 2015 Share Posted May 25, 2015 Have you tried, as the car was jacked up, with different RPM too? Link to comment Share on other sites More sharing options...
Johnny176 Posted May 25, 2015 Author Share Posted May 25, 2015 No, I just had the engine idling Link to comment Share on other sites More sharing options...
supra matt Posted May 25, 2015 Share Posted May 25, 2015 (edited) Silly question but have you checked the oil level or replaced it lately, also how is the flywheel? As there daulmass and do give up after a while I would check its still within tolerance Edited May 25, 2015 by supra matt (see edit history) Link to comment Share on other sites More sharing options...
Johnny176 Posted May 25, 2015 Author Share Posted May 25, 2015 Yep 1 3/4 liters of Royal purple was put in when the box was put back in after changing clutch Flywheel looked in good condition, clutch was replaced because I went single rather than it wearing out. I thought a dodgy flywheel might have caused the car to shake and judder when on the bite butt this doesn't happen to me Link to comment Share on other sites More sharing options...
Pig Posted May 25, 2015 Share Posted May 25, 2015 Mine has a brand new spec flywheel and system fully bled. I found an easy solution to resolve the problem - Take the car off the road whilst I save for a proper clutch and a new gearbox. Link to comment Share on other sites More sharing options...
supra matt Posted May 25, 2015 Share Posted May 25, 2015 Can you get it up on a ramp while someone operates the peddle to make sure it's fully depressing also I belive fitting an na slave cylinder gives a longer throw, as this could be the problem as have read about it before, Link to comment Share on other sites More sharing options...
