Overdrive Light Flashing???

Hi there, I just recently did a tranny swap in my 96 bronco after destroying my old E4OD. I put the new tranny I got on craigslist in and it ran flawlessly for the first 20 or so miles and then the problems hit me like a damn wall. The first problem I noticed was that my tranny wasnt shifting into overdrive, then the overdrive light starts flashing. This is where I start questioning things...WHY IS IT DOING THAT??? I put 3 gallons of tranny fluid with the engine running like im supposed to, but im just not sure why it isnt shifting into OD

another one for yall, shortly after this OD problem, everytime I start up my truck, the RPMs are higher than usual. Since its the base model, I dont have a Tac so idk what the RPMs are running.

Any help is appreciated! Expect me to come back soon because I have more problems with it that im still trying to figure out.

btw, its getting me probably 4mpg...so I really need the help!

What does the dipstick say???

If I remember right, the E4od takes more than 12 quarts. I think it's around 22 from dry to full.

Flashing OD light means there is a diagnostic trouble code.

Dry fill on an E4OD is about 18 quarts. A used trans isn't going to be dry, so it will take less.

You MUST read the codes to fix this. Anything else is just guessing.

When I swapped the tranny in, I put 4 Gallons in it. But I went to O'Reilys earlier to check the codes and it was something along the lines of my Throttle Position Sensor.
Also before I even left to go to O'Reilys I found out that my headers weren't bolted up completely and hot exhaust was pointing straight up to the bottom of the trans pan. Also I unplugged the VSS in the rear end and dumped abunch of dirt out the connector. On the way over to the store it started blinking again so it was no surprise to me...put $10 of gas in it and it never came back on, on the way over there and on the way back. I went ahead and disconnected the Negative battery cable for a couple minutes and started driving it around...and that was the best its driven in a while
