when you put in gear is the engine rpm going up....when you hit the throttle...?

Have you checked the transmission fluid level and condition? Usually if a transmission wont do anything it's fluid related.

remove the upstream O2 sensors and see if the problem lessens,,,,physically remove.....if so the cat is /or exhaust is plugged..

also if you have a severe exhaust leak near the engine the KS may retard the timing severely.....

check the KS connectors for security and corrosion....
