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 3 ) through a strainer. Inspect the strainer for metal

debris or excessive clutch material.

Does the strainer have metal debris or excessive clutch material?
