While we're on this subject, I recently had to replace the 2 speed housing. Since then it seems to me like it is stuck in 2nd gear. No shifting, sluggish off the line then about mid rpm it gets going well...but never a shift. If the one way went bad, it wouldn't shift to 2nd right? Pretty sure mine is in 2nd from launch.
Things I have done to TRY to help.
1. Replace 2 Speed housing.
2. Replace 2 speed shaft
3. Replace shoes with new shoe kit, to include springs, shoes etc...
4. Adjust screw to 5.5 turns out from bottom.
5. Make sure set screws in middle of shoe were not interfering, nor pushing the shoe out.
What else can I try?
