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

The pressure control solenoid 1 (PCS1) is a pressure proportional to current (PCC) solenoid used to control on-coming, off-going and holding pressure to any 1 of the 5 clutches. The transmission control module (TCM) provides voltage to the main modulation (MAIN MOD), torque converter clutch (TCC) and PCS1 through a separate solid-state device called high side driver 1 (HSD1). The TCM regulates the amount of current to the PCS1 by switching the low side driver ON and OFF.

DTC P2729 is a type A DTC.
