PD79: Transaxle Steady State Adapt

Display shows pressure from zero to +127 psi. This value is the increase in transaxle line pressure that PCM is commanding through the transaxle pressure control solenoid during steady state, not upshifting or downshifting condition. PCM increases line pressure to control clutch slippage. Normal value is 0-10 psi. A value greater than zero psi means that PCM has detected some clutch slippage (not during transaxle shifts) and is raising transaxle line pressure to decrease transaxle clutch slippage.
