Don’t let your Mercedes-Benz faulty gears grind you down!
It’s nothing new to encounter problems when owning and operating a motor vehicle. It happens to the best of cars, including Mercedes-Benz.
One issue that may grind your gears is an issue with your grinding gears! When your Mercedes has such issues, they can be dangerous and should be corrected immediately.
We know how beautiful your Mercedes looks on the outside, but the inside can sometimes tell a different story. If issues are left unsolved, they can build up, and then you may be faced with a bigger bill and in the worst case scenario a vehicle going on the scrap heap! Whatever the case, once you encounter an error with your Mercedes-Benz, you should book in for a diagnosis.
Diagnosing the problem
Mr Fry has brought his Mercedes S Class 2012 to our experts here at Fergies as he had an issue with clunky gear changes when changing down through the gears. The main problem was that the gear change was rough and didn’t accelerate or decelerate smoothly.
We had learnt through checking the Digital Service History (Mercedes DSB) that the car had never had the gearbox serviced, and the car had done over 100,000 miles!
Let’s fix the problem!
It was essential to start by completing a full service on the automatic transmission to diagnose the issue. We also removed and replaced the sump oil pan filter and all related seals and then replaced the oil drained so far.
The next step was to carry out an automatic transmission mega flush service using 15 litres of the correct grade gearbox oil. The best way to do this was to replace the old oil with the new oil with the vehicle running, as this will change 99.9% of the oil in the gearbox oil and will make a massive difference to how the car drives.
Finally, we reset the adaption values, and we checked and carried out a transmission software update. We also set the gearbox oil level correct at 45 deg C before taking the car for a test drive. The Mercedes was now like a different car! The drive was smooth, and the gear change issue was no longer evident.
