01 ram 2500 4x4 46re

was rebuilt or swapped out at one time if u look at it and compare it to tehr est of the truck its spotless, shifts hard anytime over 3k rpm? so was it built? always in overdrive, did a burnout and i let off the brake pulled away and let off the gas after i got the truck straight haha. went to get on it and it acted like it was in neutral, reved way up and i think the spedo read 45mph just as the tires got traction and i started to gon one my way. but after i let it rev down i pressed the gas again and it was fine.

so did it shift into over drive when i let off the gas doin teh burnout and when i went to get back on it was it trying to down shift to like 2nd, or did it go right to first and just bounce off rev bc i was moving already and it didnt think i was.

im lost on this matter, and srry its a bitch to explain on the internet. just want to know if its goin out or wat
