Advance Adapter

The GM 700R4 adapter to the Land Cruiser 19 spline transfer case is 6.750” in length. And the overall length of the transmission and adapter is 30.125”. The adapter material is 356 T6 heat treated aluminum alloy. The adapter kit includes an adapter housing, 19 spline spud shaft, new 700R4 output shaft, transfer case shifter bracket, transfer case brkt spacers, transfer case input seal, sealed bearing, gaskets, fastening hardware, and adapter instructions.

Note: When using a GM auto, we recommend a new front transfer case flange yoke. This new front flange is 3.5” in diameter vs. the standard flange 4.250” to 4.500” will aid in front drive shaft clearance. Refer to PN716370, PN716371, or PN716369.

Transfer case

This adapter assembly fits August 1980 to 1989 transfer cases. The transfer case design was changed to a split-case design configuration with a 19 tooth internal spline on the input gear.

Transmission

This kit is designed for exclusive use with the 2WD 700R-4 / 4L60. The overall case length of the transmission is 23.375”, has a non-removable bell housing, and a 4 bolt square rear case. This is the first automatic overdrive that GM produced. Introduced in 1982, this transmission is offered in two different bellhousing / case designs (60 & 90 degree bolt patterns). All 4.3 V6 & GM V8 installations will require the 90 degree version. The internal components of these 700Rs can be interchanged if necessary. When this transmission was first introduced, it quickly developed a bad reputation for certain weaknesses. In 1987, GM resolved all of the problems that previously existed. In the 1990s, the name of the 700R transmission changed to 4L60. These transmissions are ideal for many conversions because of the 30% overdrive. The overall length of this transmission is 23-3/8”. It has a 1st gear ratio of 3.06:1; 2nd 1.62:1, and 3rd gear ratio of 1:1. This transmission has a computer lockup for the torque converter. We offer a 700R lockup bypass kit, PN24-700R.
