Update: They have had the transmission apart for a week and have decided they are going to replace the torque converter now. I may have it back tomorrow or Monday. That will be a total of 25 days in the shop if I get it Monday.

I have had my 2012 Gt for 2 weeks now and have put a little over 1000 miles on it. Today as I started it up and put it into drive it waited about 2 seconds then clunked into gear. I pulled out onto the road and accelerated at a regular speed and it ussually shifts out of first very quickly, this time it let it rev all the way to 3000 rpm's and then shifted and the service light then came on. After this one shift it drove normally all the way to the dealership with no other problems. I turned the car off at the dealership and told them i needed to have it checked. They went out started the car and the light was not on anymore so they pulled it to the back to pulll the code. One of the service people then called me in and said I may have been reving the car too high because the code came up "incorrect gear ratio". I then had to explain exactly what happened so they wouldn't think I was abusing the car. Has anyone else had the same problem or even know why a "incorrect gear ratio" code would come up? They said if it happens again they will have to look into it further but I don't think they really knew what the problem was.
Happens to me all the time during the winter if I don't let the car warm up for a minute or two. Yes, even in AZ it can get chilly here during winter (below 40F). Let it warm up, and rather than just drop into D or R, go all the way down to 1 then back to D. That will force fluid through all the gears and keep it from holding a gear when cold.
Don't know about the gear ratio error other than the fluid is too cold to allow proper shifting so the PCM trips the code thinking you're the one that is holding that gear.
P.S. I have an '08 with 33K and this slight annoyance only happens during cold weather and only when I start it up after letting it sit to "room temp".

The car has been in the shop this time for 2 weeks and 2 days so far for a total of 27 days of the 2 1/2 months I have owned it. The service department called yesterday and said they were going to replace the computer in the car. Today they called and said they ordered a new transmission and are going to go ahead and replace the whole transmission too. Hopefully this will solve the issue.
