Determine if DTCs P0745, P0746, P0756, P0758, P0761, P0763, P0766, P0768, P0782, P0783 and P0789 are present. These DTCs must be eliminated first as a possible cause for DTC P0732.
Check actuator operation. See ACTUATOR QUICK CHECK under ADDITIONAL SYSTEM FUNCTIONS. Operating sound of all actuators should be similar. If 2nd line actuator cannot be heard operating, inspect actuator and replace as needed.
Check pressure regulator valve operation. If line pressure does not change or changes slightly, regulator valve is stuck. Repair as needed.
Air check 2nd clutch operation.. If 2nd clutch air checks okay, disassembly of transaxle will be necessary to inspect internal components.
Cross-channel leaks may cause other clutches to be applied. If PCM detects other gears are stuck on, other DTCs will be present. This may help locate cross-channel leak.
If clutch applies and releases, check valve body for damage. If clutch does not operate, check for failed clutch plates.
