Nice but,
if you back it up too far you run the risk of dropping the ball into the bottom of the case. if it gets up into the geartrain, you'll be buying a new trans.
I've never backed mine up that far!
Thanks AJ, the copper washer is .080", so I do understand what you're saying, it does put the ball out farther from the tube its in. Thankfully the ball stayed in place when I test shifted it. I need to find a thinner copper or fiber washer and change it out again. I won't go back to the stock washer though. Thanks for the heads-up.
