Overdrive not working
Hi, guys. I have just installed a new e40d Racer x Transmission in my 1997 f250. The overdrive does not seem to kick in. I took apart the shift lever and found one of the three wires running through the lever had wore through. I was able to splice the wire together that had shorted out. I now have a constant overdrive light on. When I press the button for overdrive nothing seems to be happening the light just stays on steady. When I drove the truck a bit and get to about 40mph she doesn't shift up and is running at about 2000rpms or so. Can anyone tell me where the wiring for the OD switch goes to after it enters the steering column? I am thinking maybe the switch is bad, but unsure at this point. Any input would be greatly appreciated of course. Thanks for your time. CJ

Thanks for the bump Todd. Just to update things. I replaced the switch in the shift lever with a new one from Ford and still have the same problem. It won't go into overdrive. I did take it for another test drive and the overdrive kicked in for about 1000 yards or less then the OD Light flashed a few times as if going into limp mode then the transmission down shifted back into 3rd (I believe it is). It just won't shift to the upper gears. With it revving so high at greater speed I am reluctant to drive the truck for fear of burning up this new transmission. If anyone has any ideas i am all ears. Thanks

</td></tr></tbody></table> Test the red-yellow wire at the switch for power, "Key on" position.
If that test good you may have a fault in the white-light green wire running between the switch and computer, pin# 32.
I came across this post while searching here tonight. I think I will be looking into the switch wire to the computer next. (crossing my fingers).

Fourth gear IS overdrive! It doesn't have 1,2,3,4 and then overdrive.

When the OD light flashed it set a code. You need that code to figure out what's wrong. The places that read codes free CANNOT read these codes, you need either a good independent shop or a Ford dealer to read them. Once you have the code number (not just the description) we can help you find out what's wrong.
