P273BTransmission Friction Element H Apply Time Range/Performance

P273B indicates that the transmission control module (TCM) has detected an abnormal apply time or performance range for friction element H, which is a clutch or brake inside the automatic transmission. The computer commands the element to apply and monitors how long it takes to engage or whether it engages within the expected window, and it sets this code when the measured time falls outside the programmed range.
