1993 Chevy K1500 4l60 to 4l80 swap
 

theres nothing wrong with the trans other than im sure it wont live behind a 396 stroker for long and it just needs serviced so i could probably just service it and sell it but what all would need to be done to swap a 4l60 for a 4l80 in a 1993 chevy truck? i got one a few months ago with a seized motor rust free with good interior just needs a paint job for 500$
