SYMPTOM
P0753 - TRANSMISSION 3-4 SOLENOID/TRANSMISSION 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 difference than the expected voltage.

POSSIBLE CAUSES
- Fused B(+) feed to transmission control relay open
- Transmission control relay
- 3-4 solenoid control circuit open
- 3-4 solenoid wiring harness intermittent defect problem
- 3-4 solenoid wiring harness
- Shift solenoid control circuit shorted to ground
- Solenoid and harness (solenoid control circuit)
- Solenoid and harness (solenoid pack connector)
- Transmission relay output circuit open
- Transmission relay output circuit shorted to ground
- PCM (3-4 solenoid control circuit)
- PCM (code set)
- Powertrain Control Module
