I just had a reconditioned transmission put in my 1994 7.3 f 250, the truck has been running good for about two months but I recently took it back to the dealership and they said it was low on fluid....however I took it to another mechanic prior to that for an unrelated problem to the transmission and when I got it back the trans seemed to shift funny to me and the overdrive light on the shift column is now blinking, the ford dealership did not mention anything about the blinking light but as I said they put fluid in it and said those models do shift hard in forward and reverse. I was also told I had bad valve cover leaks, fuel line leaks and power steering leaks.......I took the truck back home and when I checked the parking spot where the truck sleeps....there are no spots in the driveway anywhere !
man, its hard to find a good mechanic, it seems like I have to play investigator everytime I deal with getting my truck fixed. any ideas why the overdrive light blinks ?

Oh, the overdrive button still works .

 

OD lamp is blinking due to the trans having error codes in it. need to findsomeone that can get the codes out and tell u what is wrong

 

Funny thing , I found a blown 15 amp fuse in the box and the light went out after I replaced it ! what was that all about ? is that all it takes for a 94 7.3 to shift up and down and act up ?

 

no idea. never had a E4Oh no.

 

depending upon where you live i am a mobile mechanic and im always looking to help some one in need ...... let me know im sure im cheeper that any dealer in site.....

There is more than one fuse in the fuse box that will throw your E4OD into limp mode, which is what is happening when your OD light is flashing. The #17 and #18 fuse will do it also. There are also about a zillion other little stupid non important electrical issues that the factory transmission computer reads and wants you to know about so it throws the transmission into limp mode. I also have a 94 F250 with an E4OD and it was absolutely driving me nuts with stupid crap like this. I finally gave up and spent 630 bucks on an Optishift controller to replace the factory transmission computer and I'm pretty sure that was the best 630 bucks I've ever spent! It's like I have a new transmission!

 

Can anyone tell me how you replace the od button on the shifter handle, its been broken for awhile, light started flashing on it, so I took it to a shop to have diagnosed came up code P1728? they are sugesting I have tranny rebuilt, I bought the truck brand new and never have I had any problems with tranny, so thats why I would like to start with button first then go from there, my rig is a 1995 F-250 7.3L 4X4, could some one please help?
