97 Taurus OHV, AX4N with 250,000 miles. I've had the car since 70K and have had no major problems. I've changed the Tran Fluid 3 times (2nd was a flush). A month ago it started slipping out of gear at stops about 90% of the time. Shifting into neutral and back will usually do the trick. If not then shifting it into Park and back will. No other slippage problems. The third fluid change was right after this started happening with no effect. Could it be a sensor problem or is it just dying of old age? Transmission shop said they will check it out, just haven't been able to get to them as I am out of town alot. Just trying to get a feel for it first.
