First off, the washer that goes between the pod and the shift lever doesn't actually do the indexing, so replacing it probably wouldn't have any effect. What the washer does is firmly hold one side of the mechanism so it doesn't move when you move the lever. The indexing is integral to the shift lever mechanism; I've never pulled one apart to the point of being able to see or replace the indexing bits, and I doubt replacements are available.
However, if the issue is that you get a few clicks and then smooth action, I wonder if the internals might not be worn but some how out of alignment, such that you are actually only clicking through the lowest few gears of the shifter and then moving past the indexing. My thought is that worn internals would not result in smooth action, but rather crunchy and/or imprecise clicks. Here's what I would try: remove the washer and shifter mechanism from the pod. Hold them together in your hands, or rig up some kind of bolt and spacer to hold them together, and try to rotate the shift lever relative to the washer and see if you can't rotate to a place where you get the proper number of clicks. If you are able to find the orientation of washer and mechanism where you get the proper number of clicks, move the shift lever to just past the most clockwise click. If I'm right, you should be able to then re-install the shifter mechanism and washer (in the proper orientation, with the keyway down) and have the shifter be able to click through it's range on the pod then. One gotcha to remember: the proper number of clicks in an index shifter is one less than the number of speeds, since the initial position is also a speed. So 10 speed shifters have 9 clicks, 9 have 8, 8 have 7, etc. On Wednesday, October 12, 2016 at 9:49:00 PM UTC-7, Hugh Smitham wrote: > > Well it sure would be nice if they were repairable.
