    2004 DTS hard shift

    Bought the car 3 months ago, has 134k miles. Have noticed that once the car gets heated, after an hour or so of nonstop driving, it will start to get a hard shift. Otherwise, shifting is unnoticeable. once I'm driving and this happens, if I pull over and shut the car off for just a few minutes, the problem goes away. the hard shift will come back after continuing on for an hour or so. Weird. Also, when this is happening, I notice that it shifts roughly when I put it in park or reverse. Took it to my mechanic for a quick check...said the fluid looks good and the screen tells that a tranny service was just done. Any ideas at all?

    Just got the codes. There are a few related to the power seats and radio, but here are the rest:

    TTM B1327 History - very low a/c refrigerant warning
    ABS U1056 History - loss of communications with RSS
    PCM P1811 History - maximum adapt and long shift
    IRC U1016 History - loss of communications with PCM

    If you want or think the other seat/radio codes are relevant, I will post them.

    Thanks.
