This is the only upgraded torque converter for the AMG 722.9 transmission used in many AMG models (See Compatibility List Below).
Our engineers have completely redesigned this lock-up style converter to achieve a 2500rpm stall speed. The higher stall speed
results in improved take-off and low-speed acceleration, improving performance both on the street and at the track while maintaining
factory drivability.
The 722.9 Torque Converter is computer-designed and manufactured with machined billet internals to ensure quality and consistency.
The result is an upgrade with benefits that improve the performance of every car, from the daily driver to the +1000HP race car.
In our thorough testing, we found that average 60-foot acceleration times dropped as much as 2 tenths of a second. It is well known
in both the industry and among enthusiasts, that any improvement in 60-foot times translates to even greater improvements in quarter-mile times.
The Weistec Torque Converter upgrade works best with Weistec ECU tuning software, and is 100% compatible with factory electronics.
Please supply the VIN of the vehicle in which the converter will be installed
