C4GP Auto Selector Not working

[kainfs]

Hi.

After some nuggets of wisdom.
My 2012 C4GP Auto displays Gearbox Fault :Repair needed.
As a result it doesn't auto shift.
The only way to cycle up through the gears is to drive, pick up speed, shift to N the back to M so, its still driveable.
Not seen similar posts so any tips ideas would be most appreciated.
I've already taken it to a clutch specialist who couldn't diagnose the problem. He said the ABS sensors are all good.

Thx

You'll need it diagnosed to find out exactly what's wrong.

If it's the piloted manual (EGS) system it can be lots of things, including clutch wearing / actuators etc.
If a Proper Automatic (AM6), again we'll need some fault codes.

When you have these pop them up with your VIN (automasked on post submission) , ort if you're not sure which box you have still pop your VIN up and we'll let you know.
