Only reason im considering it is that the truck is so cheap, and really clean. Has an e40D, its issue is that if you put it in drive it just goes nowhere, but if you manually shift it from 1, to 2 and then into D or OD it drives fine. Seems to me that the tranny isn't blown but something weird acting up?

 

Have you checked the Transfliuid. My Chev TH350 did that but it was 3 quarts low on fluid.
