so when I bought my 04 2wd sport trac, the o/d off light was flashing even though I hadn't pressed the button and cruising down the road, if I press it the rpm shoot up. ended up replacing the module on the transmission that the shifting cable attaches to and it fixed the flashing light, about three months ago (maybe longer) i was blowing if some steam and running it through mud holes at the river and on my way home i noticed the light was flashing again but my overdrive still wasn't off. I just told myself it was a sensor or something on the module saying it was off because it was faulty. now a week or two ago i was backing out of my driveway that is on a slope but the transmission was slipping and i had to give it more gas than normal to get out. as i shifted into drive i noticed the check engine light had come on as a result. i took out my obd reader right there and pulled a code saying there was a problem with the output speed sensor on the transmission. i just changed the fluid a month before this but i cleared to code to see if it would come back and it hasn't yet. now I'm dropping mpg bad as in a trip to the next county over that usually would take 1/8 of a tank now takes 1/4. i cant find many other problems like this but I'm hoping someone can point me to another thread or help because for the past month ive done nothing but baby the truck because im scared the transmission is gonna go out and a highschooler that works at chick-fil-a part time cant quite afford a new transmission
