Good afternoon gmt junkies. I have a problem and could use some expertise. I just put a used 5.7 into a k1500. I bought it with a blown motor. Has a rebuilt tranny though for sure. Previous owner said its been replaced this year and when I dropped the motor there wasn't a spec of dust inside the bell housing. However I just got it up and running and it doesn't want to shift when under throttle but has no problem doing So at just over idle. When input it in reverse I have to give it about 2000rpm before it moves backwards. And if I give it WOT in overdrive there's a vibration through the floor and a metal on metal rubbing noise. I put in a new tps so I know that's not the issues. Any help please and thank you!!
