Technical issues and repair guidelines

Many experts assume that this transmission has its design peculiarities which require some skills from repair specialists. This transmission is maintenance-friendly, it has a huge resource for transmission components and can serve for a long time, when following the rules of operation and visit a repair shop for well-timed overhaul and replacement of repair parts.


In many cases, repair specialists have to fix the torque converter and replace rubber and plastic spare parts. In most cases, technicians have to replace all friction elements, even if they haven't exhausted their resource.


The electric board with speed sensors get out of order because of regular overheating and contaminated ATF. Operating with the faulty valve body and electrics leads to general oil starvation, wear-out of bushings, vibrations and wear of other units of 722.6 series. Separators of rear and front overrunning clutches are frequently replaced in the process of repair services.If the transmission is used with a worn-out torque converter for a long time, then vibrations and metal debris damage not only bushings, but also friction surfaces of the pump cover. In this case, masters replace the pump cover with gears. Frequently, it is required to replace a rear bushing of the K2 drum, which is damaged by vibrations from unevenly wornout frictions.


The repair of the 722.6 torque converter is one of the most demanded and highly-priced procedures because of the transmission complex design and record number of spare parts. The operation of the 6th series automatic transmissions with the faulty torque converter has a negative impact on the valve body. Therefore, it is recommended not only to completely change ATF, but also hand in the torque converter for replacement of the friction coupling.
