Clutch Tranny probs? Help a brutha out!

'98 M3 slv cp 120,000 miles

Hey all, I looked all over the posts and couldn't find anything related to my car problem. So here it is...please help me diagnose?

Yesterday I blasted from 0-110 mph backhanding this whore-of-a-lexus IS300out of the toll booth (paid at the same time) into the expressway.

Well, got to where I was going and stopped at a stop light. So I put it into first and when taking off, it felt like my clutch wasn't catching and the car was shaking and the clutch pedal was really shaking. I had to let the clutch pedal out a lot more than I normally do. And I was really slow starting. When I was in gear my car accelerated properly. It only felt this way when the clutch was pushed in and I was at that higher RPM takeoff point. I switched gears ok...& then from there it seemed fine.

It also does the same thing when in reverse. If I start the car in second it doesn't do the shaking as much. I think a smelled a burning, but I'm not sure. Also, get a sort of noise when the clutch is pushed in at idle. No noise in neutral. Never changed the clutch to my knowledge and I bought the car 9years ago@ 50,000 miles. The fluid was full as I just replace brake system like 4 months ago.

Is it my clutch? Trans?

Thanks for your help...Kid Chris

Engine or tranny mounts? Maybe some looseness in fasteners around that area? Driveline instability? Get her in a lift and do some prodding

if there is a noise when the clutch is depressed it means the release bearing is on its way out, even when a gearbox is in neutral the input shaft is still turning with the clutch up so thats a good sign, you need a clutch either way as the bearing is gone so just get someone to look over the rest as they will have to remove prop etc anyway, to me tho it sounds all clutch related!!

Sounds like you popped one of the retaining tabs on the pressure plate, on the stock clutches theyre only 2 layer tabs, aftermarket pressure plates are usually 5 layer tabs - thats common on the M clutches especially if it is a STOCK BMW clutch - theyre worth about their weight in scrap metal.
If you got a smell.... Clutch disc is probably slipping
I recommend a clutch upgrade as your next mod !

Happened to me on my sixer...

The little piece was actually wedged in the newly formed "bellhousing vent"



It can be harmful to your health!
Had not one, but two clutches go that route. also two orders of subsequent tranny damage. (first one was cracked a third of the bellhousing)
