There are many service bulletins describing the diagnoses and repairs, which include fluid leak repairs, transmission software updates, or internal failures requiring a costly repair.Google+

Transmission seemed to be doing fine, but without warning upon getting on the hwy one day, while accelerating up to speed my transmission stuck in I believe third gear, pulled over right a way and checked transmission fluid. Quite surprisingly the transmission fluid did not register on the dip stick, I had kept it checked pretty frequently that is why I was shocked to find this. I purchased Lucus Transmission treatment fluid and immediately filled transmission fluid until it registered right. Yet it still stuck in third gear upon driving it right after I put the fluid in. I then didn't drive it for a couple of months. Then tried driving it again and the transmission seemed to change correctly although the O/D light blinked on and off and when I got out of the vehicle I could smell a slight burning of something under the middle/back of the vehicle underneath. I then took it to Bob Sight Ford in Lees Summit MO. they told me that when the transmission fluid didn't register, when I first became aware there was a transmission problem and I put Lucus in it, it had leaked and blown back covering the back underneath of the vehicle with the transmission fluid,and that was the burning smell I noticed, that it was all that fluid that had leaked out burning off. They also told me that the transmission was fine at that time and they didn't note any problem with it. Upon picking it up and leaving Bob Sight Ford the O/D light began to flash on and off and it sliped in I believe third gear, not sticking in third gear like it did when the fluid first didn't register. I am driving it currently very carefully but it currently slips in third gear and the O/D light flashes on and off each and every time I drive it, it goes off upon turning the car off but starts flashing without being able to turn it off until the vehicle is turned off, and it starts flashing within driving it no further than 1/4th of a mile. I think, am not certain, but I feel like it might be a seal that has gone bad, not sure but certainly a problem within the transmission. Currently haven't been able to get it fixed because I am not sure I want to invest the money if it has to have a total rebuild of the tranny because I am not sure the vehicle is worth it with the year and high mileage. Not to mention previously I had to have a total rebuild on my previous 2000 ford 2200.00$ and not four months ago I paid 950.00$ on the transmission on my current 2004 chevy trailblazer.
Seems to be slipping in third gear.
