I have a 1992 F150 with the 4.9 six and a E4OD trans. The truck stalls when i put it into reverse. The engine revs a little bit then clunk, stalls. The 4.9 runs like great and idles perfectly. I don't think it's an engine problem. It runs too good. I have to take my foot off the brake and give it a little gas when i shift into reverse to get her going. The rear abs light comes on when the truck stalls and for a few seconds after it is restarted. Does this mean anything?
