Hello Again All Teeners,
After 100 little projects I have the silver bullet (silver '74 2.0) back on the road, first time it has been registered since 1984. Runs great, needs paint and perhaps a tranny freshening?????? I replaced all of the guide nylon bushings and re-centered the stick shift. However, when down-shifting 3rd to 2nd is horrible, (GRIND!) better when I double shift. First to second is ok, though at times if I am too aggressive it too will grind. WHATS NEXT ON MY LIST????? remove the 1st and reverse section of the tranny? Complete rebuild? Can hardly wait! Many thanks for all of the great guidance over the years. CTC911CTC |

Easy stuff first- Make sure clutch the cable is adjusted to disengage clutch when the pedal is 1/3rd of the way depressed.

I agree, first make sure that the clutch pedal is at the complete top of its travel and that you only have 1/2 inch of play before it gets hard to push, and that there is no first reverse grind at a complete stop. If all of that is good, it is the transmission, second gear in a down shift grinding is usually the first to wear out. If you cannot stand it, new sliders, syncros and dog teeth will solve it. Any shop will charge ten labor units to go through it. Labor is not bad, parts are. Special tools are needed to press off the dog teeth and check the ring gear and pinion depth |

Thank you VERY much for the reply.
Not sure I am ready to attack a 901 tranny - I have the books and can buy the jigs, as to the parts, is there a standard -rebuild kit- that you would recommend rather than take it apart and order what is necessary??
