There are so many things that can cause this problem, start with the check engine code, that will be the first clue.
I changed maf sensor both o2 sensors new cat new speed sensors new tranny filter an fluid radiator flush cleaned trottle body new air filter an box I'm running outta ideas my next guess is torque converter cause it only does it when the car is cold
