Transmission stuttered once accelerating from a stop light, again later driving approx 35 mph changing lanes; slight acceleration. Then noticed the engine light was on, so I pulled into a parking lot, stop the car and began checking the vehicle manual which indicated possible emission issues +++. Began researching where the closest GM dealer was located.

I turned the engine on, put it in reverse, checking for clearance behind me then stepped on the accelerator.... the engine revved and the car started to drift forward towards the vehicle parked in front of me. "No Reverse?" Good thing I left plenty of parking clearance.

I then researched were a transmission shop was located. After the vehicle ahead of me pulled out I was able to drive out of the shopping center... once on the main road had to put the emergency lights on because the shifting into 3rd gear would like slip, going into a high rev, letting up off the accelerator allowed shifting to progress. Thank goodness the Tranny shop was only 1/2 mile away.

A couple of hours later the shop called that a couple of codes indicating possible electronic faults may be the cause. Now waiting for follow up.

I feel so much like Johhny G. who reported the first complaint back in Nov 2014. I will have to find out if the same PO776 code was thrown on my vehicle... I will update later.
