Common Faults:

Mercedes CLK 7 speed 7G-Tronic transmission ECU faults will cause running symptoms such as sticking or holding in gear, harsh up and down shifting, difficulty in the selection of any gear and forced limp home mode. A host of RPM sensor fault codes, P0705 - Transmission Range Sensor (TRS) Circuit Malfunction, 0717 - The Signal From Component Y3/8N1 (Turbine Speed Sensor, VGS) Is Not Available, 0718 - The Component Y3/8N1 (Turbine Speed Sensor, VGS) Is Defective, 0721 / 0722 - Y3/8N3 Output Speed Sensor Circuit and 2201 - The Component Y3/8N2 (Internal Speed Sensor) Is Defective are all commonly stored when this gearbox ECU becomes faulty. Internal component breakdown is common but can be rectified by our test and rebuild service. If I purchase this will it cure my fault?

Gearbox electrics 5/5

I've been dealing with them many times before. Just recently I been using ECU Testing for two Mercedes problems, one conductor plate speed sensors and second one gear selector faults. Both repairs done by ECU Testing goes perfectly smooth, both cars working lovely, no problem at all. Well recommended company. Excellent customer service

Transmission Control Module 5/5

The service from ECU testing was first class. I sent them the control module from my Mercedes CLK350 7G-tronic gearbox. They contacted me immediately upon receipt, kept me up to date of its progress through their system and returned it to me repaired within a few days. I was able to get my transmission repaired for a fraction of the cost it would have been from Mercedes, thanks to ECU testing.
