- CLS500 2007 219 5.5L 7g Tronic gearbox
We have a CLS500 (5.5 V8) with auto gearbox but have never been able to select the gears manually but now Im on a mission to sort it. The gearbox works 100% smooth in C or S settings however if I try and nudge the gear lever (no steering wheel paddles) to the left or right when in drive the car remains in auto with 'D' shown in the instrument cluster.
Ive done some searches on this site and not found anyone with a similar fault although a few years ago I had a Jeep Grand Cherokee and these were famous for having the same issue which was usually resolved by cleaning the contacts in the gear selector. Has anyone had similar issues with there Mercedes??
I've checked for fault codes with a DSB2 tester (Icarsoft MB Ver2) and no codes present in transmission section. I can see the gear position on the OBD tool but when nudging left or right it still doesn't change on the OBD tool either. When my son took it into Mercedes for a service he asked them to look into the gearbox issue but they just came back saying it changed up and down smoothly which we know already but they didnt address the fault and Im loathe to give them a load more money if I can help it.
Any suggestions of remidial action or areas to check would be much appreciated. Its an absolutely awesome car with endless power but I just want it fixed to make it perfect.
MAny thanks in advance, Andy
