2011 Focus LX LV Transmission Woes

[russellw]

Your LV Focus should have the 4F27E transmission which is a 4-speed auto.


Before going stupid why not at least try the low cost approach of replacing the Trans range sensor. It if has failed then the ECU won't know what gear position is selected. It's located on the side of the trans housing and you can start by checking the electrical connector. That error can also be caused by a fault in the wiring to the trans control module (TCM) and there are pinpoint tests for that if replacing (and adjusting) the TRS doesn't help.
Have a read of Section 307-01A in the WSM (available on this site) for more info on how to adjust the TRS.
