Question about 2006 Chevrolet Silverado 3500
I sure hope you are not Towing in OVERDRIVE...
If a P2563 is found, it may be caused by an unstable Solenoid Control Valve (SCV). Unstable SCV operation may be induced by engine debris or sludge. To diagnose an unstable SCV complete the procedure below.
Test the VPS (Vane Position Sensor) operation. Actuate the VPS plunger and monitor the sensor voltage on the Tech 2. The VPS body should be grounded during this test. Touch the brass body of the VPS to the turbo center housing to complete the ground. Voltage should go from 4.9v to 0.25v as the plunger is depressed. If the sensor operates correctly, go to next step, or replace the VPS as necessary.
Note: It's normal for voltage to jump back to 4.9v if the plunger is completely depressed.
Command turbo vane position from 10% to 90%, back and forth, several times. During each cycle, monitor the actual turbo vane position sensor reading. The vane position should reach the desired position, and hold steady. If vane position oscillates back and forth more than 5% before stabilizing at the desired position, replace the solenoid control valve.
Note: Debris or sludge build up in the SCV can cause the valve's stability to deteriorate. This can be aggravated by not following oil change intervals and/or extended idling in combination with use of biofuels.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

SOURCE: transmission problems
One of the solenoids in the transmission is acting up go to a transmission shop and have them code the transmission. Some repair shops can also check your transmission if they have the right Diagnostic tool.

The shift solenoid in the transmission has a fault with the power train computer or visa versa. A scan of the computer codes will find your fault. Auto Zone will perform a scan free of charge just for asking

Just had the same thing happen to me. You have wires in your transmission that may have broke. Your external wire harness needs to be replaced. The shop just charged me $700 for the fix. Ignore the sensor for now, it is trying to tell you about the wires. I would take it to a shop for the fix. Your transmission will need to be pulled apart to access the wires. The wires that are broken control when your automatic transmission shifts. If they break, your transmission will not shift properly. Please feel free to ask any questions, I am happy to help.
