1999 Chevy Blazer with service engine soon light

I have service engine soon light that goes on and off. When I scanned it for codes I get a P07053. Could some please tell me what this code is, why light keeps going on and off and what needs to be fixed. Thanks

Are you sure it’s P07053? There should only be 4 digits after the P.

sorry about that I must have been more tired than I thought. I rechecked the code and it is P0753.

P0753 = Shift Solenoid A Electrical. This means solenoid A in the transmission has an electrical problem.


DTC code P0753 is a tranmission code that indicates a fault in 1-2 Shift Solenoid Circuit Electrical. Two conditions set the code. 1) the VCM (Vehicle Control Module) commands 1-2 shift solenoid ‘ON’ and voltage remains high (B+). 2) the VCM commands 1-2 shift solenoid ‘OFF’ and voltage remains low (zero).

If you can get to Alldata, there is a trouble shooting chart that will lead you through the diagnostic procedure.

Hope this helps.

Alldatadiy says I need scan tool that has transmisson output contol function. Can you tell me which one I need? Thanks
