This Super Duty 6L80E transmission uses our Full Billet torque converter, that has a very large Red clutch. Full Billet means both the converter housing and the clutch apply piston are both billet. This converter is built in-house at PATC. The Alto Red Eagle Power Packs are here and we install them in our Super Duty 6L80E transmissions. The 3-5-R direct clutch has 6 double sided clutches and the 4-5-6 clutch has 18 single sided clutches. These are two weak points in the 6L80E transmission. This is a 75% larger clutch apply area in the 3-5 clutch and a 50% larger clutch apply area in the 4-5-6 clutch. We use our exclusive PATC / Alto Kryptonite (195751X-7754) clutch lining on the other clutch 3 sets. As an added bonus this transmission has an oversize filter. You can buy the parts to build this Super Duty 6L80E transmission and Full Billet torque converter plus a core charge on the torque converter. Custom tuning must be performed to the TCM to accommodate the new parts. Call 1-888-2012066 if you need help buying the parts to build a level 2 6L80E or 6L90E transmission.
