My Chevy spark had no issues with the transmission...

My Chevy spark had no issues with the transmission however they put a recall out for the vehicle and when I got OnStar I decided it I should have the vehicle service. When I brought it in I was told it would need a new transmission and that it would be 10 to 14 days. Imagine my surprise when 4 days later they say it's ready and I pick up the vehicle and they tell me the transmission is good. fast Forward 2 days when I'm traveling up to Farmington and my vehicle begins to shift erratically in a manner that I had not been accustomed to as a vehicle had never done that before. I had the vehicle towed to reliable Chevrolet (I will also review them) and was told it would cost over $3,000 to fix the transmission. Of course I said that the transmission had been replaced to which they told me the transmission had not been replaced, merely flashed. I called GM and after a week of not having a vehicle catching rides to bernalillo they told me they were not responsible even though they were the ones who touched the vehicle last to perform the recall. As a service advisor I have had transmissions come in with well over 100,000 still functioning with no issues for power or shifting. So either Chevy thinks I'm a stupid moron or their transmissions don't last 70,000 MI which is unsettling at the least. I will never ever buy a Chevy again and any customer that walks into my facility will also know that they should never ever buy a Chevy again. I hope you guys rot for creating a recall on a perfectly good transmission that destroys the solenoid so that you guys can make some money. Dealerships are dealership after all.
