Eight-cylinders had a 1.76:1 reverse gear ratio. Converter is working exceptional on 1.76 1st gear. So, the conclusion is that the 1.76 gear ratio is a better option for high-performance usage. The mark on the input shaft should have made 1 3/4 turns and be pointing to 9 oclock if it is a 1.76 ratio. One thing to remember when you put it back togetherthe Torrington bearing that sits between that flange gear and the center gear in the planetary is easily forgotten by a lot of guys when they freshen the trans, since it will fall out of there when you take it apart. A two-speed planetary gearset with a first-gear ratio of 1.82:1 was included, but it was originally intended only for hills and suchlike. Reverse gear was 1.82:1.
