Re: 02 ranger, code p0743, o/d light flashes aswell
Hi, I don't have the answer to your problem, but I have a similar issue so I hope you don't mind if I add it in :)
2002 3.0l 2wd no check engine light/ no stored codes, but my "o/d off" light flashes occasionally. I haven't been able to narrow it down to anything specific, besides that it has only happened on starting after the truck has been sitting more than a couple hours. I took it on the highway while it was flashing and didn't notice a difference in engine rpms so I'm assuming overdrive was still functioning. I finally got around to changing the fluid so I'm waiting for it to happen again on me and figure out what my next step will be.
