Sticky auto gearbox?

[jamesdc1]

Hi,

I have a 2004 C220 CDi with 70k on the clock, regular servicing and not abused.

The problem is that occasionally, mostly when exiting a roundabout, the engine/garbox sticks in a low gear and keeps the revs up at 3-4k limiting me to 20-30 mph. If I stop and engage neutral, let the engine settle and it's ok to move off again. Problem does occur again unless in similar circumstances.

It's when I approach a roundabout or corner, take my foot of the pedal, roll into the rounabout or corner and hit the pedal again to power out - this is when the engine revs/gearing sticks and the problem occurs.

Any ideas? Do I need to change anything? Replace the gearbox oil & filer?

You help and advice will be appreciated.

This almost definitely sounds like a ATF level issue, you're right when you say you should change the oil

I suspect you will have a fault code with this.

Get it read first.

Both of the above........Fluid level check AND a code readout

Ive got a similar problem, only mine doesnt rev high, it simply 'Thumps' into the next gear. It does it going down the box as well. Usually when powering off a roundabout or pulling away / slowing down for an (upwards) gradient.
Ive had the fault codes read...no faults. Ive change the fluid four times in one day to make sure all old fluid is expelled. I bought a dipstick from the USA and the level is spot on. Still it does it. Scares the hell out of passengers! I can only assume theres a serious mechanical problem and I cant afford £3000 for a new box.
Going to look at a ford focus this weekend.

Yes, you are right replace oil and filter as well.Oil and filter have to be changed after 60000 kilometres
