For those looking to hop up their 4t60- 4t65e. Offers 50% more clamping on 3rd clutch than stock. With the Borg-Wagner high energy clutches and this, Problems of 3rd not holding will be a thing of the past. Still not sure on pricing.
One remedy was using a old 440t4 or 4t60 piston assym but won't let you install the same or more clutches in 3rd. This will solve both.
