DTC P0732: Problem in 2nd Clutch and 2nd Clutch Hydraulic Circuit

1. Warm up the engine to normal operating temperature (the radiator fan comes on).

2. Make sure that the transmission is filled to the proper level, and check for fluid leaks.

3. Drain the ATF (see step 4 ) through a strainer. Inspect the strainer for metal debris or excessive clutch

material.

Does the strainer have metal debris or excessive clutch material?
