My 87 F150, 351, auto tranny made a bang and slipped out of reverse the day before yesterday, then yesterday it seemed like it was slipping while drive in drive, then when I parked and came out and put it in reverse it wouldn't go, seamed like park, reverse, and neutral all acted like park, but
1 through Drive worked, so had to get the guy in front of me to move so I could go in drive, then today I was turning around, didn't quite make the turn, so tried reverse, it went in and stayed there, now I seam to have reverse and 5 parks. This truck is on it's way out anyway, box rusted through, almost 400,000 Km on it, or 250,000 miles, so I will probably just part out the good parts, but thought I would ask here first what everyone thinks of the tranny, is it dead, worth fixing or what?
