gear sluggish

[Germplus]

Can anyone help/shed some light…?

I have a C Class 220 CDi 2009 (W204 5 speed auto Gearbox).
Recently on occasions I have been experiencing problems with the gearbox. The car seems to get stuck in a specific gear and won’t allow any automatic or tip-tronic gear change, even if I put my foot down on the accelerator to the point where I am pressing the button underneath the accelerator pedal the gears won’t change.
It seems like it goes into limp mode. The tiptronic doesn’t work as well when this happens. When this is happening when I put it into neutral and reverse it jumps which doesn’t feel right and doesn’t happen when the gearbox is fine. Once I switch the car on and off it seems to be working perfectly fine. It only seems to do this when I am driving local as motorway once I am in 5th gear it’s not a problem.

Any help would be much appreciated.

Its 5G-tronic i think because i have never seen the gears pass 4 when im using the tip-tronic

A common failure is the switch on the Tip shift. This stops the gearbox responding.

Often it just wants a clean or adjustment.

It's inside the selector unit.
