1998 2.3 CL 4cylinder

Hello, I have a 1998 2.3 CL and I have no idea what wrong with my car, Only when its cold outside (in the mournings-below 50 degrees) my transmission seems to not work. When I put it in Reverse I jerks into reverse but moves fine in reverse. But when I Put it in D4 I barely moves. In D3 it pulles the exact same. IN second gear it moves a little better but still barely moving? Soon as the temperature starts to change the transmission will work fine without missing a beat, or if I let the car warm up for about 10 mins, cut it off and start it back up it shifts perfectly fine. Have you ever heard of this and can I fix it. OH yeah the Check engine light is on and that's because of 3 things, the computer, crank sensor and cat converter, is what I was told when I had it checked by a mecanic. Would the computer being bad have anything to do with this? Thank you in advance, strangest thing I ever heard.
