6L80 TO JEEP JK NP241 TRANSFER CASE 2.72:1

Advance Adapter

This heat treated aluminum alloy adapter is 3.7″ thick and replicates the stock bottom mount locations from the factory adapter housing. This adapter allows you to mate the GM 6L80 transmission to the JEEP JK NP241 TRANSFER CASE 2.72:1.

Transmission

GM’s new Hydra-Matic 6L80 transmissions are the first of a new family of modular six-speed rear-drive transmissions. The transmissions feature two overdrive gears and a wide, 6.04:1 gear ratio spread to improve performance and fuel economy when compared with conventional four- and five-speed automatic transmissions. With two overdrive gears, engine rpm is reduced by approximately 9 percent at 60 mph – a reduction to about 1,500 rpm. Lower engine rpm can bolster fuel economy because less fuel is used. A lower-rpm cruising speed also enhances smoothness and reduces noise heard in the vehicle’s cabin.
