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

1995 F-250 PSD, 2x4, Factory 3.5in with a straight pipe welded in, TS performance chip with canned tunes.
Missing the bed and the two front fenders are rusted beyond recognision.
One day i will have me a nice truck to put all these parts around..lol

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.
