The clutch pressure control (PC) solenoid 5 is part of the control solenoid valve assembly, which has no serviceable components. The clutch PC

solenoid 5 regulates the transmission fluid pressure (TFP) to the 1-2-3-4 clutch regulator valve, which controls pressure to the 1-2-3-4 clutch. The

transmission control module (TCM) calculates gear ratio based on the RPM signals from the input speed sensor (ISS) and the output speed sensor

(OSS). The TCM compares the expected transmission gear ratio to the calculated gear ratio for each commanded gear.

* The ignition voltage is 8.6 volts or greater.

* The high side driver is enabled.

* The TFT is 0掳C (32掳F) or greater.

* The transmission output shaft speed is 350 RPM or greater.

* The transmission input speed is 200 RPM or greater.

* 1-2-3-4 clutch is commanded OFF.

Conditions for Setting the DTC

P2723

The TCM detects an incorrect on-coming clutch gear ratio, or flare, when the 1-2-3-4 clutch is commanded ON and the transmission input speed is

200 RPM or greater from the anticipated input shaft speed for 3.5 seconds, a total of 2 times in any one range that the 1-2-3-4 clutch is commanded

on.

P2724

The TCM detects an incorrect off-going clutch gear ratio, or tie-up, when the 1-2-3-4 clutch is commanded OFF and the transmission input speed is

40 RPM or less from the anticipated input shaft speed for 1.2 seconds, a total of 5 times.

Action Taken When the DTC Sets

P2723

* DTC P2723 is a Type A DTC.

* The TCM freezes transmission adaptive functions.

* The TCM commands maximum line pressure.

* The TCM inhibits Tap Up/Down function.

* The TCM inhibits manual shifting of forward gears.

* The TCM defaults the transmission to fifth range.

P2724

* DTC P2724 is a Type A DTC.

* The TCM freezes transmission adaptive functions.

* The TCM commands maximum line pressure.

* The TCM inhibits Tap Up/Down function.

* The TCM inhibits manual shifting of forward gears.

* The TCM limits the transmission to first, third or reverse operation.

Conditions for Clearing the DIC/DTC

DTCs P2723 and P2724 are Type A DTCs.

Diagnostic Aids

Before performing a road test, configure and setup the scan tool for snapshot mode. This will allow you to display, monitor, and verify multiple

transmission data parameters at one time, after the road test.
