Torque reduction when shifting

The transmission control module (TCM) requests torque-limiting from the engine control module (ECM) in order to limit torque immediately before shifting. Torque limiting can occur at three different levels: 25 %, 35 % or 45 %. Limitation lasts for less than 1 second.

0 = No torque limiting requested

25, 35, 45 % = Torque limiting requested
