+ Rain Damage, please HELP!

Would the catalytic converter give me the shifting issue? It happens maybe once a week. I'll be in second coming off a light or something, in automatic, and it won't go to third till it revs almost 5k rpms, then I have to let off the gas cause I don't want to take off into the car in front of me. I can override it just by manual shifting obviously, but it'd be bad news if someone else was driving it and jumped off the line in taffic.

A little more detail about the door.
Pulling the handle out brings the window down, but as soon as the handle is released the window jumps back up.
So to close the door at the moment, I have to hold the handle open and push the door closed, then release quickly so the latch catches, but the window doesn't smack the plastic ridge on the convertible.

Speaking with one of the mechanics I work with, he said it could be the microswitch, but if the window is being told to pop up at the wrong time it could also be what ever tells the car the door is closed.
