Gearbox in limp mode. Bump into drive and reverse. Will not change out of 2ND gear. Speed sensor on Contact plate failed. Contact plate replaced with reconditioned unit. This was a fail. Ultimately took three units before it would work. Also proper adaption had to be completed using STAR to resolve gear changing. Mercedes dealership would not supply genuine part unless done in their workshop. Yet they also use same shop I used to program.Their quote almost three times the amount. Later found we could buy the genuine plate via a gearbox spares company for the same price of the recon unit. |

Gearbox had a false shift in second gear. required gearbox overhaul and replacement torque converter. On completion it showed a wiring fault with oxygen sensors. This was thought to be a ECU failure. But after many months of diagnosis I insisted on replacing the downstream oxygen sensors suspecting they may have been damaged when the box was pulled. This resolved the problem |
