AW-71 Transmission/overdrive/ overdrive relay.

  1. Hi Everyone,

    I haven't posted on the newsgroup for awhile, I guess it's because up to now
    my 90' 765T has running great.
    I am having problems with the tranny. It won't shift into 4th-overdrive
    until the car has been driven for about 10-15 Minutes.
    I have replaced the kickdown cable and made sure it is adjusted properly.
    I just replaced the overdrive solenoid and so far no change.
    I will try replacing the relay next.
    Has anyone replaced the relay? Can the relay appear to work, it clicks when
    cold and upshift arrow lights up, and still be bad?????
    I took it out and took it apart and the solder appears to be fine with no
    Nothing happens when I deactivate the solenoid with the button when it's
    cold but when it gets warm and I know it will shift the transmission will
    change when the button is pushed.
    When the car was cold I tried to listen for the click from the solenoid when
    deactivating it with the switch, I didn't hear the click when deactivating
    or activating the solenoid.
    That's what led me to believe it was the solenoid because it did not click
    when the car was cold.
    Am I looking at a new tranny??
    By the way the tranny was recently flushed and when I replaced the kickdown
    cable more clean fluid was added so the fluid is nice and clean.
    Any answers will be welcome.

  2. I just went through this in a 91 245...I couldn't get it to shift
    reliably, and traced the problem to the wiring between the shift lever
    area and the relay, Took it all apart and could find no fault, but
    put it all back together after tightening all the connections, and
    all's well now.

    I suspect the connection betweent he harness and the relay was my
