I have a Ford Ranger 2004 XL 2.3L 2WD Vin# 1FTYR10DX4PA98081. My Trans slips and slams into gear, have had it rebuild 3 times in the last 6 months.
I noted down one error code… P0715 and was told it means “Transmission Speed Sensor Circuit”
Sometimes after a rebuild it runs ok for a time, but within a week or two the problems start again. OD light will start flashing, then when I turn the eng off and back on it stops flashing till the next time.
The trans guy says he can’t figure out why it keeps happening.

    Sounds like somebody will have to dig into the transmission control module and its wiring harness. Didn't anyone investigate the 715 code and drill down into it?
