overdrive light flashing

I have a 1992 f150 2whd 5.0, my overdrive light is blinking. i have read numerous threads, which relate to hard shifting etc. mine now and before runs fine no shifting issues. This all started after I replaced the tps. i also just changed gears. I have no codes as I cleared them after the tps replacement. Could this possibly be the tps, or the vss? I'm sure it was banged on with the many removals of the gears to set the shims. the tps is set closed at .9 volts the idle screw was disturbed by the prior owner. i think I got back close. How do you test the vss is it ohms? I've read it needs to be 190-250 ohms on the sensor pins. I'm frustrated because I cleared the codes. Any Ideas, I'm leaning toward the vss. The tps voltages are spot on. idle good smooth gas mileage is good. I have read its not good to drive it with the od light flashing

You need the codes to diagnose this. Once the light flashes the code is stored. Make the light flash again and read the codes.

My 2008 Ford Escape OD is blinking. I experienced a hard transmission shift from park to Drive. The problem began after I got the vehicle cleaned from a washing area. I pulled the floor shift lever transmission from park to Drive, the vehicle got a slight jerking movement and hard lever movement to Drive position.
can ya help me on this?

Yes, I can. Get the codes read and we can go from there.
Or you could wait until whatever got water in it do dry out and it should be fine again.

There is a forum for Escape and Escape Hybrids. You should ask your question in the appropriate forum as this is for ‘87-96/7 F Series trucks.

A moderator might be able to move it for you. Welcome and good luck

EDIT: or Mark can help you here in someone else’s thread...
