Hi all

 

Apologies if this has been answered before, but I'd ask anyways. The clutch is slipping when I accelerate. Example, when I'm going about 60 on the motorway and I take my foot off the accelerator pedal and then try to accelerate again, it slips for a bit before engaging the gear. Normally when I'm driving slower, say around 30-40 mph, it seems fine, just when going faster. Does this mean a new clutch? apologies for my poor description.

 

Thanks

Not as easy to say with an automatic gearbox.

 

Often they have several clutches which may only affect certain gears.

 

Low fluid level could cause change issues, incorrect fluid can cause change issues.

When was the gearbox last serviced?

 

Possibly the same oil since it left the factory.

 

Valve blocks within the gearbox could also be the cause.

well I've had the car for about 4 years and haven't changed the fluid yet. And I know it's over filled as well. Am planning on changing the fluid this week, so will see how that goes.

Over 8 litres of oil in it normally for a change, make sure you drain the

gearbox oil cooler also.

 

How much over maximum is it?  I would have a container between 15 and 20 litres

just in case.

 

Normally it would be closer to 10 litres if you leave it draining for a while.

 

And warning lights or fault codes for the transmission?

Changing ATF once it's very old and the box has already started slipping usually makes it worse. An auto slush box doesn't have a clutch like a manual one does, it's a box filled with small clutches! If the clutches are very worn then all that might be allowing them to bite is the worn off friction material floating around in the oil! If you remove that then they wont be able to bite at all and all you'll have is slip.

 

If it's so bad the car is almost undrivable, or you can live without it, then you've got nothing to lose by trying to change the oil, but otherwise i'd leave it alone and keep driving it while you sort out another box for it.

 

Prevention is better than cure with this type of thing. More frequent changes would have slowed down the rate of wear earlier on.

Hey communist, thanks for the advice. It’s not really bad so I can live with it for now.
