Autobox shift speeds

[Trickythemerc]

Hi guys, Newbie here just bought a very nice 220 CDI CLK and love the car. It does seem to want to hang on to 4th gear ? or maybe it's just me ? Under normal conditions and using sensible throttle it changes into 5th at just over 40 MPH is this normal ? With 74k and no mention of a box service having been done I am going to order the bits and do it as a matter of course. Any tips and hints will be most appreciated.

Which mode are you running in? C or S or is it the same in both?

Hi pretty much the same in either C or S mode

Did you get this sorted tricky?

I found resetting the transmission ECU allowed the car to adapt to my driving style, and began upshifting at lower RPM's.

^as above. I believe gearbox adaptations can be reset via star and some OBD scanners.
