Advance Adapter

This adapter assembly fits 1974 to July 1980 16 spline transfer cases. The drive gear has 16 internal splines and a diameter of 1.259”. The transfer case bolt pattern is the same as the earlier 3 speed transfer cases.

The 6L80E adapter to the Land Cruiser 16 spline transfer case is two piece adapter assembly that is 4.50” in length. And the overall length of the transmission and adapter is 28.00”. The adapter material is 356 T6 heat treated aluminum alloy. The adapter kit includes two adapter housing, 16 spline spud shaft, sealed bearing, gaskets, fastening hardware, and adapter instructions.


 The adapter kit is designed for exclusive use with the GM 6L80E 2wd versions.  GM’s new Hydra-Matic 6L80 ttransmission is the first of a new family of modular six-speed rear-drive transmissions. The transmissions feature two overdrive gears and a wide 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. GM estimates the wide ratio spread can help cut 0-60 mph times by as much as 7 percent and enhance fuel economy by up to 4 percent. 
Our kits can use the 2WD transmission with a 6.75" output shaft with long spline stickout, however; the shaft will need to be cut or shortend to 3.80 cut off. This casting is designed for the stock 4WD output shaft.
