I am looking at a 91 k2500 350 eclb 8 lug. Will it have a a 4l80E? The add says lost reverse and the owner is oblivious when I try to get them to send pics of the trans.
It's a crap shoot, but there's a good chance it has a 4l80e in it. 350 tbi trucks, even 2500's could also come with tbe 4l60/4l60e, but 91 was 1st year of the 4l80e, and most 8 lug trucks got the 4l80e(some early builds still had 3l80/turbo 400).
