Circuit Description

WARNING: This page is about a different variant/trim than selected.

The transmission control module (TCM) modifies the transmission line pressure through the pressure control (PC) solenoid valve, in order to control shift execution time and shift consistency. The TCM monitors various inputs, and modifies the shift execution and timing by applying a calculated duty cycle to the PC solenoid valve. The TCM alters the shifting based on driving habits, transmission load, and internal transmission condition.

When the TCM detects long shifts that cannot be shortened by shift adapts during the same ignition cycle, then DTC P1811 sets. DTC P1811 is a type C DTC.
