Mercedes 722.9 Seven Speed Transmission upgrade

With increased engine performance it becomes necessary to further improve the drive line components, most importantly the transmission in order to ensure maximum power is transmitted to the drive wheels without transmission slippage. This can not be realized with software and only truly be accomplished by an internal mechanical upgrade to the transmission hardware. RENNtech is the foremost authority on transmission upgrades and has done countless rebuild and upgrades for the most demanding dealers and clients for over 21 years.

Our transmission upgrade consists of a complete transmission disassembly and inspection as well as a mechanical upgrade to the transmission clutch packs.This allows us the ability to maximize the amount of friction materials contained within the transmission and in turn, the amount of power which can be transmitted through each forward gear. Our upgrade leads to improved shift response, shift timing and greater drivability under extreme conditions without sacrificing around town comfort.

Our mechanical upgrades provide years of trouble free operation and have been tested to in vehicles producing over 800 hp and 1000 lb/ft of torque. The transmission is reassembled using all new gaskets, seals, o-rings, electrical connectors as well as a new transmission pan filter.
