700R4 3/4 Clutch Pack Configuration & set up
I'm helping a guy with a 700R4 & we were debating the merits of more friction discs in the 3/4 clutch pack. What's the differences between run 8 versus 9? There must be some type of trade off. Another question is the free clearance in the clutch pack. Stock, it's .060-.090", on 4L60's it's .030-.060" & TransGo recommends .015-.025". I can see the smaller the clearance, the faster the clutches apply. However, I would think the plates need some clearance when not applied. I've heard .005" per friction disc is a good rule of thumb. Any comments out there, both theory and/or practical driving experience. For my friend's situation, we're talking hi-perf street, not racing only.
