Clutch slip ?

[J4CKO]

My 2003 Saab 9-3 Aero occasionally slips the clutch, being remapped its very torquey (288 lbs ft) and it seems to overwhelm the clutch a bit, funny thing is it has stopped slipping and is fine now and has been for a while, how can this be the case, thought if they were on the way out that was it, if anything I thought the cool, damp weather would exacerbate it as it is ideal turbo weather.

I hadnt been using it much as had been cycling to work, weather, a dodgy tooth and travel have meant I have used it more, can clutches stop working due to lack of use ?

I beleive my model has some kind of mechanism to compensate for wear in the clutch, was thinking perhaps that had got sticky.

Any ideas ?

The engine is down on power (torque)?

Less traction in the cold weather?

I'm suffering clutch slip in mine, remapped to 300lb/ft. Seems to be inconsistent. Sometimes I can get my foot to the floor and it's fine, other times it's slipping on about 3/4 throttle.

I can only guess that there are many factors which determine how much power the car produces, such as air temp, engine temp, fuel quality etc.

One thing's for certain, every time it slips it's wearing the clutch away, and eventually it's only going to get worse.

Traction could also be a factor. Managed 4th gear wheel spin in a straight line on the motorway the other day. At least the tyres take the hit rather than the clutch!

Anything but at the moment, feels very perky.

Intermittent fluid contamination onto the friction plate/cover? If its an old plate the friction material may have worn down to the extent that the rivets are exposed and catching to provide grip - unlikely though as you would notice quite a difference in how it was engaging...

Think it was just lack of use, it is behaving itself, feels rapid at the moment.
