727 Build for Mid-10s

The reason that grooved clutches are used in 2nd and 3rd gear applications is because the oem and most aftermarket clutch material is inferior to Alto's Red Eagle material. They need grooves to dissipate heat. The forward clutch is applied at idle and remains applied thru all shifts. Not a shift quality issue; shift quality is easily varied with changes in pressure. I have heated various clutch and band materials and have found that the Red Eagle is superior to all except kevlar.
