2001 Chevrolet Silverado 1500 4wd
5.3L V8 Vortec
Service engine soon
codes =
P0753
tech = SF
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







SF:
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.
