Torque converter clutch shudder at highway cruising speed is the most reported M7WA complaint, typically appearing after 60,000 miles.
Symptoms: Vibration at 40–55 mph under light throttle, DTC P0740, shudder disappears at full throttle
The pressure regulator valve bore wears, causing pressure drops that result in soft shifts and TCC slip.
Symptoms: Soft or inconsistent shifts, transmission hunting on hills, reduced shift firmness
Long service intervals cause varnish deposits on solenoid cores, affecting shift timing and feel.
Symptoms: Delayed shifts, DTC codes in P0750–P0775 range, variable shift quality
