oK, I just got a newe job, and it starts in 36 hours,and I was heading home tonight, and I stopped on the side of the road for a second, and when I took off I noticed my tranny took an extra long time to shift through the gears, as soon as I noticed the O/D light started blinking, but not in any sequence, I don't know alot about transmissions, but I would assume the O/D light would put out a code of some sort. When I got home I checked the trans fluid and it was a little low but not much, maybe a 1/2 of a liter, so I added it, andf test drove and same thing, So I checked for leaks, or broken wires and didn't see anything! The tranny was installed less than a year ago, and I have had no probs at all! This is a 93 F-350 7.3L Turbo Diesel with AOD trans. Can anyone help?????I really need my truck on the road ASAP!!!
