727 Build for Mid-10s

The third gear clutch is applied under high rpm and greater pressures than the forward clutch. The forward clutch is applied at idle, whereas the direct clutch is applied commonly in a racing application at 8k rpm and greater. The two clutches are called upon to deliver totally different performances. Fact is, the most common repair in a TF is replacement of the direct clutch. I'm not on here to post what somebody else has already recommended. I post what I recommend based upon my own experiences and conclusions. I don't care what somebody's book says; I've NEVER read a book about transmissions. Just because Alto makes a grooved clutch doesn't mean that they recommend it. They are in business to sell clutches; and many builders believe a grooved clutch is necessary in the direct pack; because that's what it came with. So they manufacture a grooved clutch so they won't miss out on sales; period. The oem direct clutch is grooved because the materials used by Chrysler are inferior. If my supplier sends me grooved Altos; I send them back; it's just a waste of time, money, effort, and available space. If I put together a seven plate direct pack, it's more than TWICE as strong as a grooved four pack clutch.
