    Harsh shifts in 2004 Impala 3.4L

    The service light does not come on. And the DTC scan performed by Autozone did not show any codes. Is is possible that an aftermarket scanner won't be able to read the tranny DTC codes. And yes the fluid has been changed, and none off the symptoms changed afterwords.

    Harsh shifts in 2004 Impala 3.4L

    I have a 2004 Impala 3.4L with 53k on it. It has been shift harshly recently. When the trans is cold it shifts butter smooth, but after about 15-20 miles of driving every shift is very hard. If I let the car cool for a few hours it shifts great again. That is for first 15-20 miles. Any thoughts?
