gear shift selection shows park when in it and neutral. Anybody have any ideas of what could be going on?

So I installed a kryptonite stage 3 leveling kit on my sierra HD. Cranked up the keys so it’s just about level, it had quite a bit of rake to it before. Came out to a total of ~3.5 inches lift in the front and 1 inch in the back from the new bilstein shocks included. It looks amazing but my issue is it rides rough. I don’t want to lower the front and lose that nice stance it has. Can I install the kryptonite shock extenders as well with this kit to get my ride quality back? Or any other suggestions?
Hello , new to the group thanks so sorry if I’m posting to wrong group or if question has been asked before. My issue is that I bought a ‘15 1500 WT 5.3L that had around 350k with lazy #7 cylinder. So I bought used motor with around 100k from a ‘15 gmc 1500. Swapped motors out and when I went to start up I don’t get any crank, No gauges work, service error lights all come on. I’ve checked to make sure grounds are clean and tight, checked fuses inside cab and in engine bay, battery tests good, getting codes U0100 and U0102 and I’ve also installed new:
-Engine Harness (found some splits on harness that came with motor so bought new one)
-Computer (also have the original and one that came with the motor and I’ve tried swapping all 3 to see if that worked)
-Relay panel in engine compartment
Just seeing if anyone has any fix’s or tricks. Thanks
So up until yesterday the truck was driving relatively smoothly, there was the occasional hard shift from 1st to 2nd (which I believe these trucks are known for). I stopped at a stop light yesterday and started going and then at about 20 MPH the truck decided it didnt want to shift. This happened a few times throughout the day and seemed to get worse as the day went on and at this point it now does it every time it gets down into the lower gears. I switched to manual to see what gear it was stuck in and it showed 2nd and then 3rd after it shifted and didnt want to shift up.
EDIT: Transmission temps when I was looking did not appear to get above 205 F, Fluid is red like it should be, level seems fine.
Is there a known issue with these transmissions or an easy fix I can attempt? Transmissions are voodoo to me
My warranty recently expired on my 2015 Chevy Silverado 1500 5.3L and I was wondering if anyone could recommend a tuner for my year truck. I drive about a 100 miles a day at time and would like to get a little more mpg. I have access to 93 in my area as well.
Any help is appreciated.
