About a year ago I completely replaced my autotragic transmission and since they had the tranny out I told them to put shift kit and transmission oil cooler. Now my problem is that when it is cold outside and I first start the car I hear a crank noise right after the engine starts. If I dont let the car warm up enough then as I am driving the tranny drops out of gear, kinda like being in neutral, and I can not move. Engine just revs until it get warm enough then the car will grab the gears again. What could cause this kind of problem??
