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 6L60 or the 6L90 transmission to the Advance Adapters Family of Atlas Transfer Cases. This adapter can also be used for 1997 & up Jeep NP231 and Jeep Dana 300 transfer cases however additional parts including a change of the transfer case input gear will be necessary.

Transmission

GM's new Hydra-Matic 6L80 & 6L90 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.
