I have a 95 F150 4 wheel drive.The other day wile driving the od light on column started flashing.Another 5 miles I lost all forward gears.Transmission oil smells burnt.Started it up today.and it will move but there is a very noticable vibration while ideling in park or neutral.vibration disappears when put in drive or reverse.Torque converter problem or is the trany toast?Did not drive it to see if it slipps in gear.

 

Time for tubby bye bye, your tranny needs a doctor, 4r70w's are common to fail I guess. I would remove and count on replacing, my buddy had to with the same kinda probs.
