[Ford E4OD Automatic Transmission Shifting Issue]

Thank you for steering me in the right direction. Thankfully these older trucks are easy to work on.

Thanks for the reply. I pulled the harness today and found a loose connection on the plug that connects to the trans. Reseated the loose wire and problem solved. I'm glad it was something simple and not a solenoid.

I have a 91 F150 RWD E4OD that is throwing a 624 code. I've replaced the VSS, RABS,MAP, Neutral Safety Switch, TPS and IAC and it's still shifting hard through the gears. Think it's the wiring harness or could the EPC solenoid be shot?
