I've been searching for a spare.transmission since I find second gear sometimes slips slightly. How does one figure out if I need one with a notch for the flywheel sensor or one without. I'm thinking mine is without due to hall effect is inside the distributor. I do have a sensor wire going into the engine/transmission mating surface,but the wire only comes up on top of engine to a small black outlet. Test Point maybe ? Have to figure this out before ordering one.
