Stalling Ford
Q: My 1997 F-250 stalls when I put it in reverse. Sometimes it'll also stall when the truck is stopped. The check-engine light isn't on. Do you know what could be causing this?
A: I don't know what engine's under your truck's hood, and a number of engine-related faults can cause stalling similar to what you've described. But a few 1996-1998 Ford trucks equipped with the E40D automatic transmission have produced stalling during engagement. The transmission-fluid filter assembly may become loose or detached. This can be confirmed by removing the transmission-fluid pan. If the filter drops with the pan, or isn't firmly seated in the transmission pump bore, an updated fluid filter assembly should correct the problem. Check with Ford parts for the applicable filter assembly and instructions for your particular F-250. If the filter's secure, and/or previously replaced with the updated part, have the truck's powertrain performance evaluated by a qualified technician.
