Torque Reduction When Shifting
WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
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
