Sounds like an automatic transmission problem to me. Unfortunately. You will need to have a diagnosis performed to find out what is happening. First - check your fluid level to make sure it is clean and full. Second - since you just replaced the catalytic converter, there could be a chance that a wire harness was left loose in that area by accident. Make sure all wiring connectors - especially those attached to the transmission - are all secure.
