1996 and up Mercedes 722.6 and 722.9 series automatic transmissions

There are a number of reasons for the failure of the 722.6 and 722.9 style transmission. If your car is in the shop or if you are a shop, scan for error codes and use our DTC code list: DTC Code List

The switch inside the shifter, speed sensors or even an engine sensor can cause a transmission malfunction. If there are any noises coming from the transmission, or if there is metal at the bottom of the transmission oil pan, the transmission has failed. This type of mechanical failure is common.

We have determined that the single most common reason for transmission failure is because the transmission oil and filter is never changed. Old, contaminated transmission oil looses it's lubrication quality. A buildup of clutch material sluffed off over the years will make the fluid abrasive, sticking valves in the valve body as well as increasing the rate of failure of transmission gear and bearing components, creating metal shavings to appear at the bottom of the transmission oil pan also gathering on the speed sensor pickups. This condition can cause the transmission to go into limp home mode.

We require changing the transmission oil and filter every 2 years or 24,000 miles. We allow Dexron^Ž-III to be used in our rebuilt transmissions.
