    Hello All,

    I have a 1997 Ford Explorer XLS, AWD, 5.0 V8, Automatic Transmission.

    This is my dilemma: In the morning, when the engine is cold, the truck shifts fine. After the
    truck warms up, I have to let me foot off the gas for it to shift into second, third...etc .. if not
    it will shift at about 4000rpm. Truck has 202,000 miles on it - if that makes a difference.

    Transmission fluid is full, pink, doesn't smell. Last changed about 30,000 miles ago.

    Any suggestions?

    Thanks,

    Dawg

    Does the CEL come on correctly at start-up?

    With luck, can be an electrical problem and sounds like it as mechanical problems exists at all temperatures. Can be the brake or neutral safety switches, connectors from the PCM to the transmission. Metal and plastic expand with temperature, so can make contact when cold, but lose that contact when stuff gets hot. Had a similar problem with a GM vehicle, pulled all that stuff and cleaned it so I could see my smile on those connector pins and contacts. Solved that problem.

    Electronically controlled automatic transmissions are much cheaper to manufacturer than the old fashion mechanically controlled types. Penny IC's replaces those governors and modulators. But for some reason, the price doesn't reflect this fact.

    Thank you for all your responses ...I hope to look at this hopefully this weekend if it doesn't rain...

    i just wanted to throw one more monkey in the wrench and see if this may be something of significance

    I stopped this morning to get gas. After the fill up, I started on my way to work and it started shifting right. Just after 10 minutes of sitting. Here's another. after sitting all day at work on the drive home it shifts good. Has done that for the past couple of days but, it's starting to surge now. I can watch the TACH jump a few hundred RPM's as I'm driving along.

    Just thought I'd throw that out there ...

    Thanks again for all your help ...

    Dawg
