2015 prostar automatic Eaton fuller 10 erratic shifting w/ faults

Help please . Symptoms include
-erratic and late shifting
-will electrical fault out displaying forward processing and electrical fault
- tons of j1939 electrical faults
-codes for wheel base speed sensor and transmission output shaft sensor
- will resolve the fault after a few minutes but happens again multiple times a day.

Truck is barely drivable I’m going for broke here .
(First time truck owner)

 

I can’t remember them they got cleared this morning trying to see what new codes come back up..

It’s got 625,xxx miles got a new clutch mid September .

 

The only two codes I got for now are - mid 130-transmission fmi 14 Sid 49- abs control status.
Mid 136 brakes, power unit, fmi 2 Sid 231.

then tons of j1939 codes that got cleared but will come back soon. The only two that I know are constant are the wheel based speed sensor, and transmission output shaft speed sensor. Those two pretty much immediately flash back up when you clear it . Also when the truck freaks out looses its gear and throttle becomes un responsive it flashes spn 886 fmi 14 will reset after a few minutes but happens 15 plus times a day.

 

It was my tcu that was bad
