PO 758 Shift Solenoid 2 Resolved

[PACK MULE]

Getting a 758 code when the truck warms up and after driving for about 15 minutes. Replaced #2 Solenoid and problem is still happening. Wiring harness inside transmission checked okay.

When truck is cold and just started it shifts normal.

Truck is a 1996 LX 450

Any suggestions on what to check next? Not getting any other codes. Have checked harness by EGR tube, it is not touching and we wrapped this with heat tape several years ago. Not seeing any damages around plugs on tranny or noticeable wiring issues.

Thanks in advance for suggestions

I replaced all my solenoids and then found a loose muddy connector to the tranny/solenoid. Not sure where the mud came from.

Finally got this resolved. Broken pin inside connector by starter. Would lose connection once truck was warmed up. Nuetral safety switch circuit I think along with wires going to ECU.
