Possible Causes: - Shift solenoid valve A (On stick.)
- Shift solenoid valve B (On stick.)

- Pressure control solenoid valve A (On stick.)
- Forward and direct clutch assembly
- U/D clutch
- U/D brake

(so the FSM then has you conduct many tests to find true cause.)_A/T are very very complex animals.did you connect a scan tool that can SEE ALL factory DTC codes>if not , you are blind.. cheap readers dont do that. they blind you.the TCM can tell that 4th is not attainedby seeing the VSS speed too slow, that means the tranny is slippingor is not in 4th gear, or the VSS fibbing its buns off (clean it , reset code, and drive)
