Man; I just read your tread title and it was like OMG this guy´s tranny again???
In my case I´ve cleaned the Throttle-body, changed the IACV and all pressure hoses. Now the car is better. The shaking issue occurred when RPM drops below 650; the car shakes. Changing all that stuff solves it because in my case it was a pressurization problem.
Now; about temp. Is the cooling system working in normal condition besides the temp gauge bouncing? It could be a problem in the cluster panel.
About the lights; probably the battery isn’t holding charge. You will need first to check voltage in you alternator + battery using a multimeter. If it’s not them could be battery terminals loose or corroded.
