Transmission issue

[Hazrat]

Hey everyone, I purchased my W205 at 33k miles from approved used dealer.

Ever since I had the car, been having issues with transmission, within the first month it went back for an oil change as master tech thought that would cure the issue, it was jolting and gear changes were jerky. Vehicle then went back for valve body change on the gearbox, then had resynchronisation, then had adaptation, the last one had torque convertor replacement, my issue was still there ! took it to the dealership last week, this time they have said its to do with brake clutch failure, extended warranty and Mercedes wants them to strip the gearbox down to check why it has failed. Im worried now if warranty doesnt cover this part? anyone had similar issue?

They should cover it. Its not a common issue at all. These gearboxes are very reliable.

Thanks bud, the gearbox had loads of issues, dealership said they will strip the gearbox apart for investigation, if its down to driver error then warranty wont cover it. But I had issues since 2020, if there is an issue then it would be existing issue which may have caused, the torque convertor was replaced 5k miles ago and im still having issues with the gearbox jolting

If the issue has been present since the first month- but not resolved after numerous attempts - then they have accepted that there’s an issue and it’s theirs to resolve.

If they finally get to the bottom of it, and it is fixed once and for all, just remind them tht they’ve been trying for x months and that you reported the issue - and that they’ve tried to fix it from within the first month of your ownership.

If it’s been an issue throughout then it’s for the dealer to fund, not the warranty.
