EXEDY 4L60/E Family

The 4L60/E family has long been haunted by premature 3-4 clutch burnup; a decades-long problem where builders are seeking longevity. Over the years there have been various attempts to address this: from the changing the friction material and steel plate thicknesses, to the aftermarket trying extra thinner plates and single-sided plates. None of these addressed the root cause.
The proprietary current OE engineering and manufacturing technology used to produce millions of frictions per month, EXEDY has incorporated micro-waves into their already durable 3-4 friction plates for the 4L60/E family.
This design has undergone 16 months of extensive durability testing to ensure success. Micro-wave technology is used in current vehicles to help fuel mileage by considerably reducing parasitic drag in unapplied clutch packs. Using this methodology, micro-waves applied to the 3-4 clutch dramatically reduces heat generated in 1st and 2nd gear by keeping the plates cooled and separated prior to apply.
