Starting last night my overdrive light has begun flashing with erratic shifting. I have codes p0232 p0713 and p0708. I changed the range sensor and that code didn’t go away. Google tells me it is likely the solenoid pack but would like some insight before I drop the 200 dollars…I have a filter and fluid already so if anyone has had this issue let me know! 2000 f250 7.3 with 4r100

this morning I hooked my scanner up and watched the voltages of those two sensors on my 35 minute drive to work and they were fine. I watched the TFT sensor voltage drop as the trans heated only reaching about 120 degrees so it would appear that I only have these issues when the trans is hot about 160 degrees or better
plug is in good shape and I inspected it as far as I could reach it
That means absolutely nothing. You haven't done anything to diagnose the problem with the wiring.
Having two circuits that show codes for high signal almost always means there is a wiring harness issue. You need to check the circuits to the TRS and to the TFT for continuity, short to power, and short to ground. Or take it to a shop that specializes in wiring issues.
Clear those codes and see what returns. That P0232 is a fuel pump secondary circuit code. Fuel pump relay underhood can cause this, or the inertia switch behind the passenger kick panel, or the wiring between the relay and the fuel pump.
Do you have a way to watch fuel pressure while underway? I recommend installing a gauge permanently on these trucks when possible - eliminates a common cause of no starts with these old rigs.
Since you are reading TFT, it is likely intermittent. If the code is current, Mark's recommended wiring checks are the next step.
Same with the range sensor. Connectors or wiring is suspect if code returns, followed by the sensor itself. I'm surprised mine hasn't gone out with all the handling I've done with it removing and replacing the transmission.

I’m taking it to a buddies tonight that is way better at wiring diagnostics. The weird part is typically the issues arrive in the evenings and not in the mornings not sure if I’m not getting enough heat in the mornings to mess with things or what the issue is but we are looking into harnesses tonight
