when car temp is cool it runs fine. Has soon has it gets a little hot, it starts bucking into gear has it changes. I drive it work everyday on the highway for 30 mins and it works fine. But if i take it into the city and ive been driving in traffic for awhile it acts up again.

Have it scanned for trouble codes. You will probably find codes for the trans pressure switch or max shift adapt.
