High rpm shifting=problem - Honda Prelude Forum

H0ndaPr3lude · 09-02-2009, 05:11 PM

Hello,
I got h23 MT prelude and now i have the following problem:1st gear sometimes doesnt shift.At high rpms(6000+) it is hard to shift from 1st to 2. From 2 to 3 the tranny is grinding and sometimes it goes to 5 instead of 3.
It shifts well when rpms are lower.I've bleeded the clutch slave cyl. but no effect.Got XTD stage 2 kit before 5K miles.Also replaced tranny fluid(was 10W40) with MTF, but high rpm shifting is still a problem.When the engine is off shiftings are still rough... Any advices?

The clutch releases very low,could master or slave cyl. make a problem ?

mine does the same thing but it only does it when i go to shift from 3rd to fourth.it sometimes puts me in 2nd which sucks. (only done it once lol ) but i have figured out that mine just may be the shifter i have in the car. idk.. hope you get it fix ^.^

Yes, either cylinder could be a fault as well as low clutch fluid or air in the system. Check the fluid level and bleed the **** out of it first, then check the cylinders for leaks.

no air,no leaks ,there is enough fluid...

Bad clutch cylinder then. I can't tell you which one, but the slave tends to go first. I bet there is something in the Helm's manual to check them. Need a link?

yes, please

A bad hydraulic cylinder could explain the grind and difficult engagement. It wouldn't, however, play any part in missing gears/going into the wrong gear. Whether that's a problem with the car or the driver is another question.
