Experienced Mercedes-Benz 722.6 (5G-Tronic) specialists since 1987. Free computer diagnostic, lifetime warranty on rebuilds.
The 722.6 (5G-Tronic) was Mercedes's 5-speed automatic used throughout the late 1990s and 2000s. Simpler and more mechanically robust than the 722.9, it's still in many Chicago-area Mercedes vehicles. Common failures are the valve body and torque converter — both well-understood and cost-effective to address.
