Forgot to check this thread when I made the original post in the Fourth Gen sub forum. Hopefully this question won't be too much of a bother. I'm gonna' quote it here. Thanks, guys.
"Hey there guys, sorry to bother you with what might seem like a really "basic" question.. but I'm a little paranoid, so bare with me.
Last night, coming home from work, I decided to take an uphill corner a fairly decent rate of speed. I came into the corner at around the middle point of the gear (I believe I was in 3rd, was definitely "within boost") and upon reaching the point where the automatic transmission should have shifted into 4th, the car seemed to lag, shift, lag, and then apply power back to the car.
After this harsh shift, I noticed that I had a check engine light come on, coupled with a blinking cruise control light. At that point, I babied the car home, parked it, and allowed the car to cool down for the night. Upon inspecting the car when driving into work this morning, I'm still showing lights.
I'm going to try to bring the car into a local parts shop to see if they wouldn't mind putting it on a scanner for me, and letting me know what the code might be.. but for now, I'm stuck inside; wondering.
Are there any 5EAT owners who may have had this happen to them as well, or have heard of it? I didn't believe myself as being too hard on the car during that short sprint, as I was not wide open on the throttle, or doing anything that I feel I couldn't do in a similar vehicle without worry.
Any insight would be greatly appreciated!
Have a good one!"
