I'm in the market for an NSX and, so far, every '91 and '92 I've seen or inquired about fall w/i the questionable snap-ring range. Here are my q's: Is there a way to visually inspect whether the snap ring is correct or not? A technition told me that he thought that there is an inspection hole in the tranny where it can be seen. Is this correct? Also--aside from repacing the tranny, which the local dealer told me is what they do to correct it, is there a less dramtic/expensive way to proceed . I'm talking preventively, not after a snap ring gives way?
