P0753 Trans 3-4 Shift Solenoid/Trans Relay Circuits

SYMPTOM
P-0753 TRANS 3-4 SOLENOID/TRANS RELAY CKTS

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 difference than the expected voltage.

POSSIBLE CAUSES
- Fused B(+) feed to trans control relay open
- Trans control relay defective
- 3-4 solenoid control circuit open
- 3-4 solenoid wiring harness intermittent def
- 3-4 solenoid wiring harness observably def
- Shift solenoid control circuit short to ground
- Solenoid and harness def (solenoid control ckt)
- Solenoid and harness def (Solenoid pack conn)
- Trans relay output circuit open
- Trans relay output circuit shorted to ground
- PCM defective (3-4 sol cntl ckt)
- PCM defective (code set)
- Powertrain control module defective
