E40D O/D indicator flashes sometimes
I have a 97 F250 SD 4x4 with the auto trans and occasionally the "Overdrive OFF" indicator on the gear shift flashes and shifts harshly. When I shut it off it does not ususally start up again until it has gone some distance, but I haven't been able to establish a pattern there. I use the truck to pull a large stock trailer and it was running hot a few days ago, but never flashed the check engine light. I am thinking a bad connection on the harness to the tranny. I smelled the oil and it does not smell burnt. The truck has ~217k miles, but runs great and uses no oil, and has no leaks. The manual says take it to a dealer ASAP, but that usually incurs a lot of $$pain$$ and doesn't always fix these intermittent problems. Any thoughts or inputs welcome.
Thnaks, Ron.

E40D problem
I checked the codes last night and there was nothing new there, then I took it for a drive and it behaved fine. My wife took it out today on a 15 mile run with the trailer and it worked fine again, so I am thinking it is wiring. I washed out the rad a few days ago and washed some of the engine at the same time, so I am suspecting a poor connection somewhere.
Thanks for the inputs, I will keep posting if it returns, in the meantime, I will check all tranny connections.
