Does the lubegaurd stuff help the 5spd's with the G3's in the C3/C4? I have the 5-4 & 3-2 harsh no throttle downshift, seem's to be a C3 release issue the frictions are just to grabby wich is a good thing most of the time. Mine even carries on in reverse after moving the shifter to nuetral for a couple seconds when cold= grabby C3's. Just curious why I have never notice the C4's doing the same thing? I always thought it was a the release timing for the C3's and TCM tuning that's unobtainium would be the only fix? I have never felt it in a built 6sp and it's not everytime in the 5spd's kinda intermittent for all the ones I've been around and it's only been those two downshift scenarios coasting with no throttle input and worse when trans is cold.
