Had several of those trannies thru here for rebuilds. They worked pretty good for foot flat on the floor, pull stick hard, touch the clutch for us poor guys that still wanted decent street manners. As long as the gear teeth were sharp it was a cheap way to do it, one less thing to get the slider by. We had a $50 tool set and $5 in our pocket so DC sliders and gears were out, and try doing a nice grind every other tooth out of a slider or gear in your backyard with basic tools. Even with the teeth missing it will get the next gear up to speed.
