Dear professionals, and all PRELUDE owners. I have a problem with my gearbox. When driving slowly (normal mode) nothing bad happens, but if fast to accelerate (5500 rpm on 1 gear and more) the second gear doesn't want to clutch in.
How do you think - where is the problem? And how bad it is?
Manual gearbox / Honda Prelude IV H23

P.S.Hopefully my English wasn't so bad.

 

Do you get a grind when you try to shift?

 

I'd try the easy options first. Clutch slave cylinder and master cylinder alright? Check to see they're okay then bleed them to clear any air bubbles.

I had a similar issue a while back where the clutch pedal would drop to the floor at high rpms and would not release the clutch. At normal RPMs it was fine. It ended up being a bad slave cylinder.

No. On small Revolutions nothing at all. But when 5500RPM or more - just doesn't want to switch from 1 gear to 2. Not always, but time after time. No noises, no vibration. Just YES or NO.

Yeh, some guys from Preludeclub, alsou told me that this could be a clutch problem... But it was really strange for me... You are trying to say that on high RPM clutch is not fully disconecting and don't allow to switch between gaers?

I don't know well english tech-terminology, but hope you got me.
