It uses a TH-125 (FWD).
Open the hood and watch the engine for movement when holding the brake and giving the engine some throttle. BE CAREFUL! No one in front of the car, set parking brake, chock the wheels.
If the engine tips up more than it should, the mounts are shot.
If that looks OK, it could be CV joint related. Does it make noise when driving in a tight circle in either direction?
