DTC P0753 1-2 Shift Solenoid Control Circuit - this code does not mean the shift solenoid is bad . It states control circuit , wiring , the driver inside the PCM , power to the circuit .

Important: Before clearing the DTC, use the scan tool in order to record the Freeze Frame and Failure Records. Using the Clear Info function erases the Freeze Frame and Failure Records from the PCM.
Record the DTC Freeze Frame and Failure Records.
Clear the DTC.

YES - Go to Step 3
NO - Go to Step 4
Inspect the IGN 0 fuse for an open. Refer to Circuit Protection - Fuses in Wiring Systems.
Is the fuse open?
YES - Go to Step 12
NO - Go to Step 5
Use the scan tool in order to command the 1-2 SS valve ON and OFF three times while listening to the bottom of the transmission pan, a stethoscope may be necessary.

Go to Intermittent Conditions in Engine Controls - 4.8L, 5.3L, and 6.0L
Go to Step 5
Turn OFF the ignition.
Disconnect the AT inline 20-way connector. Additional DTCs may set.
Install the J 44152 jumper harness (20 pins) on the engine side of the AT inline 20-way connector.
Turn ON the ignition, with the engine OFF.

check water in the radiator, check for overheating, sump and transmission oil levels, drive belts, abs and tract control system
have the fault codes read to determine what cause the limp mode setting.

There is a spring loaded tension pully that needs to be depressed. I believe is has a 1/2 inch square socket female end on the front of tension pully that you can use a 18" or 20" breaker-bar to get leverage to reduce the tension. Reduce the tension remove belt and just reverse the process to install new belt.
