NO man 1, man 2, D, OD, or reverse (all gears gone)
2003 f350, 4x4, 260,000km (162,500mi), trans flush and pan filter 200km(125mi) ago.
Problem: no trans operation what so ever. Fluid level and condition perfect (flushed 200km ago). NO debries found in pan at time of flush. no codes at moment.
How it happened. I was diagnosing a cold start misfire, after a while required to warm engine up, so placed in reverse and reved up a bit (like a stall test) to create some friction and warm things up. rear tires started spining so backed off throtle a bit, I have done this on many trucks and no problems up to this point, then started hearing a squeal (sounded almos like and exhaust leak) then all of a sudden truck stalled, trans temp got only up to 170 deg F. placed in park, engine started fine, but all gears gone. I will be removing the pan and inspecting everything.
possibilities: of the top of my head, i suspect low line pressure, pump failure, input/intermidiate/output shaft splines.
Any one has had this "no gears" concerns? if so what was the problem.
