Thank you GMTECH for your response. I looked at the TSB you suggested but do not think that it fits. The 1-2shift works well on this vehicle. The "slip occurs from idle as if the transmission is partially engaged then grabs a few feet after it starts moving. This occurs before the 1-2 shift.

Another thing I thought of that might be associated with this issue is that when the car comes to a stop there is an audible click as the transmission shifts down to 1st. The harder I brake the louder the click and under heavy braking I can feel it downshift. This might be normal for this transmission but it seems to me it should be smoother than it is. This click is consistent, not intermittent like the first issue I mentioned.

Thank you.
