2005 Corolla RPM drop when shift into 4th Sign In

Hi all,

I have a 2005 corolla XRS at about 140k. I just had a sport clutch put in a year ago. Whenever I shift into 4th gear and accelerate, the RPMs drop by about 500 and I lose power for 2-3 seconds before it starts going back up. Other gears are acting normal. Best part is that I let my friend drive the car earlier and since he did it's been doing this. Any ideas?

Thanks!
Mike

Check engine light on? If so, have it scanned and write down the code numbers.

Yes do that as DS suggested. Any chance this "friend" beat the snots out of this or even if not if this thing is living a hard life are motor mounts all good? Can't say why that would pick on one gear but free to check them for too much motion,

No check engine light. I have the service light on but thats because I'm past the miles that were set for the next oil change. I went out again last night and it didn't happen, then today it was doing it again but in both 3rd and 4th gears. It seemed to happen less if I let the clutch entirely out before accelerating after shifting.

??!! Of course you let the clutch out (engaged) before you accelerate except from a stop. You are just burning up a clutch if you are part "riding" it for more acceleration and not sure what the heck this different clutch is all about but can't think of altering much that helps anything.


IDK what you expect but this is a Corolla not some dragster and enough miles and age that how well you treat it is going to matter,

Apologies I phrased that wrong. I meant waiting for another second after the clutch pedal is out before accelerating.

Do you feel any shaking/vibration when this happens?

Nope just temporary loss of power/rpms. My friend thinks the clutch plate is sticking. Possible tranny fluid problem?

Sorry if confused but clutch is supposed to "stick" when you aren't touching the pedal or it would be slipping and higher RPM noted not necessarily lower but upshifting that's the idea as you stay in range of RPMs for the speed you are going.


I'll bet you know the feel of when to shift and drive the thing. I get ever lovin GABERFLASTED at how many people have absolutely no clue WTHeck is going on,
