2001 Chevrolet Silverado 1500 4wd 5.3L V8 Vortec.
Service engine soon
codes = P0753
Question = I have never had any problems out of the truck. The SES light came on and I lost 1st and 4th gears. When i take off from stop its in 2nd gear and then shifts normal to 3rd, but that is it that is all the shifting it will do. Reverse is fine. Code says its a shift solenoid. I don't know where that is and how big of a job to replace. Please help...Thank you.
P0753 is for the 1-2 shift solenoid valve. It is located on the rear portion of the valve body. Removal of the transmission pan is required to replace it, if in fact it is faulty. Some testing of that solenoid and wiring is required to determine that. This code can also be caused by a loss of voltage to the trans. Main connector that feeds that, and other solenoids in the trans. Usually you will also have codes for other solenoids as well if there is a voltage loss to that connector. A problem in the 1-2 shift solenoid valve or its circuit will cause all the problems you are having.
