95 F250 7.3 auto blinking OD light and hard shifts...

My truck has been Blinking the overdrive light on and off for about a year now, But everytime i would restart my truck it would stop and shift fine. Now today, it started doing it all the time if i restart it and go to take off again, it starts like a second after i start going, and shifts hard. Shifts through all the gears fine. Someone help

Possible solenoid, but we are all shooting in the dark unless you scan it and give us some codes.

Exact same problem... I got 4 codes in my 94'. here they are.
23: Throttle sensor out of range or throttle set too high - TPS
43: (R)HO2S sensor not reading (run at 2000 rpm's for 2 minutes and retest - check for HO2S switching)
(M) Was lean at WOT for 3 seconds or more - Fuel control
63: Throttle Position Sensor (TPS) signal too low TPS
99: (R) ISC needs to learn (Let idle for 2 minutes, Erase memory and retest)
Transmission EPC circuit/solenoid failure - Transmissions

Just replaced the Throttle Position sensor 3 weeks ago.

Any Ideas? I'm kind of thinking a ground or other bad connection somewhere.
