We'll pull the engine and trans ourselves (again) if we have to. At this stage it would only take an hour. We're not sure if the filler tube is supposed to slip in or not. Since we didnt have an engine or transmission in the car when we got it, it's all new to us. We dont even know if the transmission tube is for our car (came in one of 10 garbage cans full of parts). If the tube is supposed to slid in after the engine and trans are installed, then we probably have the wrong tube. Has anyone done this before?
