My hold button was pushed by accident and I thought I had turned it off, but now when I'm driving up an overpass the transmission doesn't shift gears correctly anymore. I can feel it try then shift weird. I'm a single mom and have 2 jobs...any help would be awesome. Would disconnecting the battery for 15 minutes work like suggested in another post? I have a 2007 Aveo sedan..tranny fluid was flushed and refilled last yr as well as new belts, plugs, wires, timing belt, water pump, brakes. A/C doesn't work due to a hole in the compressor. Going to the last Nascar race in Homestead and was going to drive my car, but now with this issue it's making me nervous..a 550 mile drive for me.

Thanks so much for any help..
