Hello I have a problem with my 02 gp gt 3.8l. when driving last night I tryed to pass someone stepped on the gas and no acceleration. Engine will come up in RPMs, but takes forever to shift. Sometimes would shift hard before, but no real problem. Would kind of shift if I did it manually, but no acceleration from tranny what so ever. Can get up to 40 - 50 mph, but takes forever to get there. Could it be the torque converter, or is there a sensor for the torque converter? Any help would be greatly appreciated.
