I'm thinking after working with it tonite there is a weak spot in the tps harness where it goes to the main harness. Really hoping

I have an 05 foreman 500 at. Was getting stuck in gear. Changed angle sensor, started throwing a tps code. Put stock angle sensor back in still throwing tps code. I greased the plugs on sensor. Done the re learn code, still throwing a tps sensor. Even took computer loose to clean connections. I'm at a dead loss, where is a good place to start from. Since I have had it, i have got it to shift right one time. Left battery un hooked for a few weeks and shifted great that night, next day back to the same bs. Any help would be greatly appreciated. And the only code popping up on the dash is tps, I have not touched the tps sensor, except to grease the plug after it was throwing that code.
