A883 2nd & 3rd question

TB; I fix those teeth regularly. Almost any tranny. Ok, havent run across a tranny yet that I couldnt fix those teeth on. Its not difficult. My trannys have all been done. Some more than once. If you pull em out at first sign of trouble, it just takes a touch-up. I got spare trannys and parts . Havent yet needed them. Kinda like the spare back window. Havent needed that yet either.Or.............
