Diagnos my Shifting Problem

airbrat · 01-21-2003, 01:24 PM

whenever I shift inbetween gears my RPMS actually raise momentarily when I depress the clutch. Kinda like when you're riding the clutch or a newbie w/ a 5spd.

any reason why my RPMs rise like that when shifting?

sounds like a slipping clutch.. Time for a new one..

Q:: my clutch plate has the flywheel riveted to it.

Is it more cost effective and beneficial (in the long run) to buy a nice clutch AND like..a fidanza alu flywheel?

is there anything else that would cause this???

I disagree. I don't think it's a slipping clutch. I may also be misinterpreting your description of the problem.

The rise in RPMs that you describe: this happens when the clutch is pressed into the floor, correct? If it were to happen after you let off the clutch (while it's engaging) then I would lean towards a slipping clutch. What you're describing, however, sounds almost like a stuck accelerator cable that's causing the engine to rev freely when the clutch is pushed in.

If you're driving hard and shift quickly, does your clutch grab well and do the RPMs drop right into the next gear and off you go? Or does it engage slowly and the RPMs kinda stay up for a sec then slowly go down?

Lastly, how does your car idle?

you're right. the rise in RPMs happens as I push in the clutch, not disengaging it. Its odd because it is never consistant. Maybe once or twice a week this might happen.

My idle is great. Once the idle was bouncing from 800 to 1500 rpms! I had no idea what the hell was causing it so I disconnected my battery and let the ECU reset. Ever since I had no problems.

I doubt it does. bolted to most likely. the friction surface is probably riveted to the disk hub, but every car I've seen has the flywheel bolted to the pressure plate.

If you mean your pressure plate is riveted to the flywheel, then it is pointless to have a clutch at all as the engine cannot disengage from the transmission

??? which is it? pushing in the clutch IS disengaging it.

I'm sure you could have figured out what he meant, even though he used some terms incorrectly. He clearly stated that it happens when the clutch is pushed in (disengaged).

I would recommend using the stock flywheel, but that's just me. I'm sure the Fidanza units, and other aluminum flywheels, will work fine though. Lots of people complain about low speed driveability with light flywheels, but it's nothing to be too worried about.

And just so you get a clear understanding of how things work, and what terms to use... the flywheel is bolted to the crankshaft. The clutch disc is in between the flywheel and the pressure plate (which is bolted to the flywheel).

sorry, got my words all mixed up. the rise in RPMs is only when I push in my clutch "disengaged"
