Question about 2002 Ford F250 Super Duty SuperCab
OD button only active ocasionally so Overdrive disable and light only work occasionally. Moving the gear shift sometimes makes the circuit work especially around the drive position. . I havn't really had to diable overdrive but in case I sure would like to know how. I thought I had a problem in the column and almost got got plastic off columln but couldn't get the key guard off so could not get top plastic off. I don't know trick. Notice the last time things were funtioning correctly that moving the gear thru drive made the thing work correctly. I assume there is an enable switch somewhere in the column that makes the disable switch active and is in trouble like not making contact. ???? Help please Ron
There's no enable switch as far as I know, it should light up in any gear position when you hit the button. I'm guessing there's a problem with the wires going to the switch, probably broken somewhere in the column and make contact in certain positions. You may have to pull the ignition lock to get the cover off. If I recall that model right-remove lower cover, there's a little hole in the lock body with a small steel pin in it, turn key to ON and press the pin in with something and the lock will slide out. When you reinsert the lock just turn to off and the pin will reset itself to the locked position. You'll have it apart for a while with the ignition on so you probably probably want to disconnect the battery.

Have the vehicle scanned for trouble codes,and diagnose any codes present.If no codes,or as an alternative,i have at work a Zoom Technologies box that allows me to monitor transmission function as being commanded by the vehicle's PCM,or manually override the vehicle,and take manual control of the transmission.It is an expensive diagnostic tool.If the trans is commanded manually,and 4th gear doesnt happen,then you're looking at electric solenoids on the valve body,or possibly damaged servos.Servos can be accessed with the trans in the vehicle,and inspected.If the servos aren't the culprit,then it is likely an internal problem.

The overdrive light blinking means that a fault code has been stored in the computer, this can be for many different reasons. The car isn't actually turning overdrive on and off, it is just a way to alert you of a problem. Getting the computer scanned will provide a fault code eg. P(XXXX) if you can get this code I can help you further. -Jared

I have that exact same truck and transmission and My Transmission did the exact same thing about a year ago and there was some kind of snap ring inside the transmission that broke. I originally thought it had to be an electirical problem because the truck shifted fine until OD or if i turned OD off. The 4r70w is a light transmission and i would suggest you have a shift kit put in and they make a heavier kit to beef it up.. Sorry its probably not the new you were looking for.

The best way to adjust it is to hook a pressure gage to the TV pressure port located on the left side of the transmission just ahead of the linkage. You want it to be a zero at idle but pressure starts moving as soon as you move the linkage.

sorry to say this trans has to be removed and rebuilt seems like od clutches burnt out-do you tow heavy trailer with truck as you have to tow with od off(push button on shifter)
