6L80E Transmission GM 6L80E 6L90E Level 3 Extreme Duty “Pterodactyl”

SKU: 6L80E Level 3 Categories: , , Tags: ,

Description

  This Extreme 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 sell them for the Extreme Duty 6L80E transmissions. The 3-5-R direct clutch has 14 single sided clutches and the 4-5-6 overdrive 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-R clutch and a 50% larger clutch apply area in the 4-5-6 clutch. We sell our exclusive PATC / Alto Kryptonite clutch lining on the other clutch sets. In our extensive testing with the 6L80E transmissions we have observed repeated shaft failure at the joint between two shafts and drums. TIG welding of this area eliminates this problem. Also included is our billet intermediate shaft and hub assembly. Developed as a stronger replacement for the problematic failure of the OEM shaft when high horsepower, superchargers and turbos are used. As an added bonus this transmission has an oversize filter. You can buy this Extreme Duty 6L80E transmission and Full Billet torque converter plus a core charge on the transmission and converter. Custom tuning must be performed to the TCM to accommodate the new parts. Call (1-888-201-2066) if you need help buying the parts to build a level 3 6L80E or 6L90E transmission.
