Torque Converter Lock-Up Speeds

TORQUE CONVERTER LOCK-UP SPEEDS

The AW 50-42 automatic transmission has a driving mode selector for selecting three different driving modes. E = Economy, S = Sport and W = Winter

Mechanical lock-up of the torque converter is engaged at different speeds depending on the driving mode and gear position selected at the time. In addition to road speed and driving mode, the transmission temperature and engine load (throttle opening) are factors.

All tests are done with the gear selector in D.

Lock-up is engaged at a lowest oil temperature of 20°C to 30°C in the transmission. Mechanical lock-up also occurs on 2nd, 3rd and 4th gears. When carrying out a test drive speeds in the tables should be used as a only guide , as it is hard to read off exact speed and throttle position values while driving.
