Tough to find gears past 4k RPM

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

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.

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
