* The transmission output shaft speed is equal to or greater than 200 RPM.
* 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 for 0.5 seconds and either fail case
below is achieved:
Condition 1
* Output shaft speed is greater than 60 RPM.
* The transmission input shaft speed is greater than 75 RPM from the anticipated input shaft speed.
Condition 2
* Output shaft speed is less than 60 RPM.
* The transmission input shaft speed is greater than 75 RPM from the anticipated input shaft speed.
P2724
The TCM detects an incorrect off-going clutch gear ratio, or tie-up, when the 1-2-3-4 clutch is commanded OFF for 0.5 seconds and the following
is achieved:
* The 1-2-3-4 clutch commanded pressure is 0 kPa for a calculated amount of time.
* The transmission input shaft speed is less than 40 RPM from the anticipated input shaft speed.
* The output shaft speed is greater than 60 RPM.
Action Taken When the DTC Sets
* DTCs P2723 and P2724 are Type A DTCs.
* The TCM freezes transmission adaptive functions.
* DTC P2723 defaults to Reverse, Park, Neutral, 5th, or 6th gear.
