2002 Silverado won't start or shift out of 1st
 

I pulled my trans to replace the rear main seal put everything back together and the truck would not crank at key turn. I replaced the NSS and the NSS pigtail, still no crank. Ran a switch to the cab that went to the starter solenoid, truck starts now. Take it for a test drive and it won't move out of first gear, it will go into second gear if I shift into it. What did I dick up? 5.3/4L60/4WD
