You have wiring issues if you replaced the transmission twice and both didn't want to shift correctly.

 

You didn't say what body style the 2007 truck is and that matters a ton here.

 

The NNBS (GMT-900) trucks run a completely different computer and engine management system than the NBS (GMT-800) trucks including the 2007 Classic Silverado/Sierra (aka a 2006 body style truck).

 

You can't put a 2000 engine in a NNBS truck and just have it work, way too much is different between an LQ4 and the L76 engine in the NNBS trucks.
