It's not the dogbones/cups.. Dont think it's the transmission either..The clutch bell (pinion gear) isnt being engaged for some reason... From looking at the video, it looks like the clutches are supposed to engage the clutch bell when a certain rpm is met.. (they overpower the spring and open up against the bell housing, which drives the pinion gear-spur gear-transmission gears-dog bones- diffs and finally thedriveshafts..)But at 1/4 throttle, they aint engaging??I thought maybe the spring was off or broken, but after watching the video I would be having the opposite problem if that were the case.. Who knows.. I'll tear it down and figure it out tomorrow I guess..
