I've already replaced the OEM Solenoid B, filter, pan gasket, and ATF. Wiring checks out, but the same code came back.
Transmission shifts well around town with no slipping or harsh shifts. Highway symptoms are no overdrive, no apparent torque converter lockup, and RPMs drop immediately when lifting off the throttle. Also have a faint whine that changes with RPM/vehicle speed and is only present in gear.
Transmission shop suspects the valve body. Has anyone had a persistent P0755 after replacing the solenoid? Did it end up being the valve body, torque converter, internal harness, or something else?
