clutch slip

12 posts in this topic

Hi,

I think I have a clutch slip, the symptoms are

- slight jerk when slowing down

- not as quick to move off like normal

- yellow engine management light on

- No very good on fuel

Does a clutch slip simply mean it needs a need clutch?, if so how much would it cost to get replaced?

I assume you have a manual now?

That doesn't sound like clutch slip...

With clutch slip, engine revs would rise without a corresponding increase in road speed.

When really bad, the engine can rev away quite badly without any increase in speed!

Plus, there isn't any reason the 'check engine' light would illuminate if it's the clutch slipping.

(Not unless it were REALLY bad & the electronics could detect a mismatch between road speed, the gear you're in & engine revs. Unless someone know to the contrary, I don't think the system will detect that).

Have you had someone plug it in to check fault codes? (& again, clutch slip won't show with a scan).

However:

If you're still got the auto, much the same applies, although eventually you'd get the trans warning light & 'limp-home' third gear only. It might be worth getting the fluid level checked.

If it IS an auto & it's goosed, reckon on either a rebuilt, new (£££!) or a decent second-hand 'box.

Thanks for the reply.

Its an 3.0 l Auto Sport. The last time I plugged the computer it said

48 Torque Converter Clutch - Too Much Slip, and the gearbox oil temp was 74.00 degrees C.

Today the Yellow Engine Management Light had turned off, and it seems to be driving ok. But I do notice a slight jerk when the car comes to a stop, and it does kind of rev more then it moves on the road. Possible minor syptoms of clutch slip?

  • i had the same fault on my e39 530 auto with the torque convertor clutch, try oil first as its cheapest. if not, second hand gearbox.
  • i ended up doin both

Hi, How long did they take to replace the part?

Autos do have clutches, but they're not like the clutch on a manual car.

They usually consist of multi-plate of friction material,sometimes they're one-way (lock in one direction only). Plus, the bands (metal-backed ring of friction material clamping on a drum of some kind) can be said to perform the same function as a clutch.

It does sound like your fluid is low. Worth checking quickly before the slippage gets worse! It may even be worth getting the sump dropped, new filter & new fluid. That's a lot cheaper than a new/recon (or even s/h) 'box!

Sounds like the jerk could be the g.box jerking into a lower gear just before you stop. Sounds like a good fluid change might be worth doing

Hi, How long did they take to replace the part?

i left it with my mechanic but replacing the gearbox oil and filter wasnt huge job, bout an hour i think from memory

when that hadnt solved the problem, i left the car with him, sourced a gearbox (got it ridiculously cheap after a few del-boy dealings!)

i think it was about half a day job, maybe bit longer to replace the gearbox.

depends on who you have local to you, who you have used, and who you trust

gd luck with it

id defo do the oil first as you may be lucky and cure the problem before it means gearbox replacement

BUT

when i bought the car, i thought it would most likely need a new gearbox so allowed for that accordingly

when my gearbox did its jerking thing, it threw the car into limp mode but i dont ever remember seeing an engine managemen light on, even when the car was stuck in 2nd or 3rd gear. All it did was rev its conkers off, depending on speed but i didnt get the engine light on
