please help diagnose 4l60e problem over winter the trans in our 2000 silverado 1500 went bad. we got another from a junk yard that went bad. now i just put in a newly rebuild 4l60e (new clutch's and all) in the truck and its having shifting problems. 2-3 it lets loose from 2k rpm-2500rpm and same with 3-4. the sensor that shows if its in PRND123 is a little off but it will highlight drive wen in drive. we changed the TPS because we read that could be a problem. any idea? or similar experiences how do you fix it? thanks for any help
