Hi all, Im relativley new here and need some help. I just had the transmission rebuilt on my 01 Grand Prix GT about a month ago. no complaints until i was coming back from a road trip from Michigan back to Wisconsin. I got stuck in Chicago Traffic. After being stuck in traffic for a while I noticed that under light accelertaion my car seem to shutter or viberate when it shifted from first to second. If I accelerated hard however it shifted just fine. It just happend during light acceleration. All the other shifts were always fine witn no vibration or shutter. Now ever since I came home it has stopped shuttering or vibrating. Could it have been because of the weather? It was 95 degrees that day and I had 4 adults and the trunk was full of bags. I had the transmission tech drive it and they told me that it seems that nothing is wrong and will not check it as it is shifting with no issues. My fear is that I drive my over 500 miles a week and my warrenty voids after 12,000 miles. I cant afford to rebuild the transmission again if in fact something is going out on the transmission again. Do you guys gave any thoughts? (Tranmission was rebuilt the first time as car lost overdrive and jolted and slipped into gears)
Thanks!
