What is your question?
I have an '05 Toyota Corolla with around 120k miles on it. I have noticed that while driving on the highway and I exit, once I hit the speed of about 25-30 mph, my car begins to shake and makes noises and my rpms drop to around 500, making it seem like my engine will stall. It seems as though it is not downshifting properly and staying in 3rd gear as I slow down. It only happens when I surpass 40-50 mph. Also at times after this occurs, if Im in traffic and slow down from a high rate of speed (I drive 70-75 on my daily commute) the acceleration suffers too and will take some time to accelerate, again as if it is in a higher gear (rpm will hover around 800-1k) and slowly accelerate until it reaches almost 3k rpm before it changes gear. Both these issues/problems have caused the check engine light to come on and off. When I took it to my mechanic to check the codes, it comes back as an error message with no codes. (he believes the issue is computer related) Is this just a solenoid issue or is it something bigger, or really just as simple as a computer problem? Any help is greatly appreciated and thank you

Hello, Sorry to say, this one will need hands-on diagnosis with scanning software (if it connects to the appropriate system). There is a chance that the vehicle is staying in a high gear, preventing you from accelerating properly, and making your engine speed dip dramatically while decelerating, but it could also be electronic. If you'd like a second opinion, contact one of the certified shops on this link below, and they can confirm or reject the initial diagnosis. They may get you a better price as well.
