P0753 Code
Next are you stating:
A. That you had this DTC set; you replaced the 1-2 shift solenoid and the DTC is still set?
-OR-
B. That you replaced the 1-2 shift solenoid for some other reason and since then, the DTC is set?
Otherwise...
Do you have this DTC set current or in history?
Do you have any other DTCs set current or in history?
Do you have any drivability issues or concerns?
Do you have a proper 1-2 shift?
Do you have a proper 3-4 shift?
Have you serviced the transmission or replaced any parts recently?
Normally, when this DTC sets; I look at the solenoid and it's connection, the internal wiring harness and it's connection, the external wiring harness and it's connection, and lastly if need be the PCM and it's connections.
