The complaint A 2002 Lexus RX300 with 3.0-liter engine and the A140F AWD Transmission developed a sudden issue: a loss of reverse and no ability to upshift out of first gear. Fault code P0750 “Shift Solenoid SL1 Performance Malfunction” was set. Scan tool data did indicate that the transmission range sensor was operating properly, and
When I first started the engine, the car jerked and moved forward 5’ and then neutralized.

As best I can tell there are about 60 versions of the Honda/Acura four-speed transaxle to date. Some of these units, at a glance, look the same.

This is mainly because of very subtle differences in the pieces and parts contained in these units.
