Hi Folks, Im reposting this in the 700 section to see if Some Transmission gurus can give me a clue here.

A while back I posted about a non working OD AW71. I did read the FAQ, Actually had a bad solenoid, replaced it. the OD worked a time or two, intermittently. A couple of weeks ago I drove the car 250 miles on the interstate, never shifted into OD. stopped for dinner about an hour and on the drive back to the motel it shifted ( at about 55) and worked all the way back to the motel. Next day no dice. Second trip later that week same scenario except it started working after a 45 min stop and worked for the next two hours shifting in and out of OD, lots of times.

Monday I decided to bypass the switch, relay and harness to the solenoid (even though the solenoid has clicked every time I could check it.) (stopped) My thought was that perhaps vibration might be shutting the solenoid off at speed. It worked one or twice. Since then, no shift to OD

The transmission works fine other than that.

I have done the tranny flush with the pipe to the cooler off
I have adjusted the Kickdown cable.
I have blown out the passages with compressed air, both in the transmission and the solenoid.

So folks amn I looking at a shifter valve body problem or some other issue?

Regards and thanks for your input,
Woody
