W203 220 Auto - Not disengaging accelerator on gear changes

[bigad]

Can anyone help with this problem

When the Auto box changed up gears it's not disengaging the accelerator, and it revs up by 1,500rpm between changes

Like driving a manual and changing gear without taking your foot off the accelerator.

I got told the gearbox takes a reading from the abs ring on the drivers side rear wheel. Stripped the back end down, it doesn't have an abs ring

Any advice

It sounds like the gearbox is "flaring" you need to get the gearbox and torque convertor checked out.

I'll get it looked at, thanks
