Been having this problem for a long time now.
After holding the rpm at around 4k rpm for a launch, the clutch would slip into 2nd and 3rd gear 90% of the time. This leads me to think that my clutch is toasted and need a new one. However, last night, I did a regular start on the car, rev'd up to 8k in 1st and thinking it will slip but chirped 2nd gear. I was like WTF? I guess my clutch is not bad after all(at least the disc).

My guess is that maybe when I push on the clutch peddle, the clutch doesn't fully disengage thus heating it up?

Can someone shine some light on me?

Thanks a million

 

just have your clutch adjusted that should dispell any thought it's the clutch, could just be an engine miss under certan loads or what ever.

My '89 TII would slip under heavy acceleration-Not in first gear, but when shifting into 2nd and 3rd.
When I pulled it apart in January, disc had quite a bit of lining remaining, but pressure plate had lost "clamping power". Weak springs from the heat. Replaced assembly, now fine.
