You are using a diagnostic symptom chart to diagnose an electronically controlled 5-speed automatic RWD (rear wheel drive) transmission with a strange noise in drive. Technician A says the control valve could be the cause and is an OFF-vehicle procedure. Technician B says the oil pump assembly could be the cause and is an OFF-vehicle procedure. Who is right?

This ASE A2 Practice Test covers both transmissions and transaxles that involve the drive train, which is a series of components that transfer power from the engine to the wheels. The following subjects are covered:
 

- General Transmission/Transaxle Diagnosis
- In-Vehicle Transmission/Transaxle Maintenance and Repair
- Off-Vehicle Transmission/Transaxle Repair
