P0753 Trans 3-4 Shift Solenoid/Trans Relay Circuits

SYMPTOM
P-0753 TRANS 3-4 SHIFT SOLENOID/TRANS RELAY CIRCUITS

WHEN MONITORED
Continuously with the key on.

SET CONDITION
This code is set if the voltage detected on the 3-4 Shift Solenoid Control Circuit at the PCM is different than the expected voltage.

POSSIBLE CAUSES
- Fused B(+) feed to the trans control relay open
- Transmission control relay defective
- 3-4 solenoid wiring harness intermittent def
- 3-4 solenoid wiring harness observably def
- Shift solenoid control circuit open
- Shift solenoid control circuit short to ground
- Solenoid and harness def (solenoid connector)
- Solenoid and harness def (solenoid control ckt)
- Transmission relay output circuit open
- Transmission relay output circuit shorted to gnd
- PCM def (3-4 solenoid/transmission)
- PCM def (trans 3-4 sol/trans rly ckt)
- PCM def (3-4 solenoid control circuit)
- PCM def (solenoid harness and pack)
