I have a beautiful 1995 W140 S420 with the five speed auto box. Nine months ago I had a "totally reconditioned gearbox supplied and fitted. In June the gearbox went into safe mode and wouldn't change gear.
The car spent the last two months back at the Autobox specialist. Every day I have heard different excuses. The guy claims to have rebuilt the box twice, next it was the gearbox ECU, that was changed. Next the computer was reset. Then a second gearbox was bought.
I got in a strop because the guy went on Holiday when he had promised me the car back. The I found the car had been sent ot a third garage for electrical tests. I spoke to this new garage who told me that there were no electrical problems.
I am now a bit confused as what to do. I paid =A31700 for the reconditioned box, have twelve month warranty, but the garage seems unable or unwilling to fix the problem. Any advice?
