engine overrevving during gear change??

[AL]

have been getting this problem lately, it a little embarrassing, during gear changing the engine tends to shoot up in the revs, and its getting a little annoying especially during city centre driving???

Sounds like somethings amiss the the g-box, have you checked the oil level recently? Any problems grabbing cogs?

Is it when you have the clutch pressed, or when you're releasing it, or when you're pressing it? or do you have a tip, can't remember...

sorry for hijackin the post but i have
been having the same problem when i press and release the clutch pedal when changing gears i have a manual gpx

[AL]

yeh when i press and release the clutch it happens... its really bugging me now,

TBH - I know its obvious but if you are running a manual gearbox it could be just that your clutch is on the way out!

[AL]

thats what i thought at first, but didnt
feel like that , but im just back from a drive and revs seem to have a mind of their own as if clutch is slipping, how much a new clutch
and whats paul nolan charge to fit it, jesus im nearly afraid to ask

i dont think it is someone told me to test if ur clutch is on the way out put the car in 3rd and pull away if it doesnt and it slips its on the way out i had no slipping it pulled away first try. whether this is an accurate test i dont know anyone else heard of this?

Check some of the other bits and pieces just in case - hows your clutch fluid level, and has the fluid ever been renewed? Very long shot but try resetting the ECU in case its doing something odd (disconnect battery for a while).

[kevinod]

Another thought, how low down do you have the pedal before the clutch disengages/engages? If its right at the bottom maybe it could do with being adjusted up so you don't run out of pedal when its not fully disengaged...

i had a problem similar to this is my MX3.... how is the car ticking over..... mine started out doin the revving thing when changin gears then while it was tickin over...had to replace the idler. dunno if this is what is it now but it could be....


as for the clutch test i was told the same put the car in 3rd at a low speed and if u can still accelerate normally the clutch is fine

[gt94]

No it doesnt rev when idle just put a new stepper motor in 2 months ago so i dont think its that. As for the clutch its nearly on the ground when it disengages.And it might be saturday but it is the 13th my aftermarket dials stop working 10 mins ago

Any chance it could be the accelerator peddle or the throttle itself sticking open a bit when you take your foot off it when changing ?

How did the 3rd gear test go?

[AL]

the 3rd gear test went ok

i also checked for any sticking or snagged cables, everything seems ok

A couple of years ago on a 1.6R Mirage I had a the problem of very late disengagement of the cluch and it caused a little crunching of gears when it got to its worst. The first thing I thought of was a stretched cluch cable, then I realised it had assistance (servo) and like Kevinod said it was low on fluid! The resevoir looked like it was up to the mark, but until you took the top off you could see that "the mark" was only a stain on the inside!!
Filled it up, couple of pumps on the cluch and it was as good as new!

[AL]

will give that a try, thank for all the help lads!
