Hello,
Following my post on the steering rack I decided to post my other little problem as well.
Very situation specific problem, so the conditions have to be right for this to happen.
Gearbox in S, under its aggressive adaptation (when it hold the given gear in case you want to get back on the accelerator), and usually over 3k rpms and no throttle input.
All well and good, but then when it does decide to upshift, it will do it with a violent thump (jolt) and I am getting concerned this will damage the box in the longer term.
Granted, it will rarely happen, but enough times for me to be concerned.
Has anyone got ideas of what could be the cause? 2011 E350 CDI 265 with 7G+.
Many thanks
