As I was coming home from vaca the other day, for whatever reason I tried to cut the O/D off, and it wouldn't cut off. I tried at several speeds, and even counted the gears until it got into O/D then tried to cut it off, still nothing. It isn't just the light on the dash not coming on but it isn't switching off.

 

I had a similar problem on my super duty, ended up having to rebuild the tranny.

 

well, if it ends up needing a re-build....I'm just going to swap in a 5spd since that's what I want anyways

 

Now before we go jumping to the worst case scenario how bout checking the button its self and wiring and stuff, also have you tried it at a stop?

 

I haven't tried it at a stop, and I have no clue how long this has been going on for. I immediately thought tranny going bad, but idk really....my truck has 200k on it, and the tranny has been acting up off and on for a while. I guess we will see how strong it really is in about a month when I get my 33s on haha
