Trannsmission Shutter
 

I'm experienceing a shutter every now and then, sometimes after sitting at a red light i go to take off and the car shutters like in the wrong gear, then its ok, and it also shutters sometimes on hard accelerations onto the highway like when it shifts into od, i was wondering if these were normal or do i have maybe a tcc problem, there are no stored or pending codes and other then the shutter that happens a few times a week (i drive over 700 miles a week) it runs great, fluid is clean and the car only has 70,000 miles.

The fluid may be clean but how old is it(miles)? I would find a way to check the temps of the transmission. TC shudder is most commonly caused by a breakdown in the fluid due to high temps.

GM has an updated PCM calibration that is designed to correct for the very problems you are having.

Call a dealership with your VIN and see if they have any record of your car having had a Calibration ID update (to CalID# 12214379) done.
