General Motors 4L60E Transmission Transfer Case Adapter for 1963-1973 Toyota Land Cruisers

The GM 4L60E adapter to the Land Cruiser 10 spline transfer case is 8.250” in length. And the overall length of the transmission and adapter is 30.50”. The adapter material is 356 T6 heat treated aluminum alloy. The adapter kit includes an adapter housing, late 4L60E 6 to 4 bolt adapter, spud shaft w/ 10 spline, GM VSS sensor, t-case shifter bracket, retainer, sealed bearing, gasket, nylon lock nut, fastening hardware, and adapter instructions. This kit uses a stock 2WD 4L60E output shaft with a 11” stickout that needs to be shortened. We then take our 51-0405 adapter housing and bolt it to the transmission. This adapter takes the hex bolt pattern on the 4L60E and converts it to a square bolt pattern to make the 4L60E look just like an earlier GM automatic. The stock main shaft should have a reluctor on the shaft which will line up with the sensor hole on our main adapter housing.

Transfer Case Fitment: This adapter assembly fits 1963-1973 10 spline transfer cases. The drive gear has 10 internal splines and a diameter of 1.375”. There cases are equipped with a vacuum style shifter.

Transmission Fitment: The adapter kit is designed for exclusive use with 1997 & up 2WD 4L60E / 4L65E. The transmission main case and bellhousing on this version are no longer cast together (now a removable bellhousing design), and no longer had the square bolt pattern on the output side. This version of the 4L60E is now equipped with a hex bolt pattern similar to a TH400. This transmission is 21-7/8” long and is used in both 2WD & 4WD vehicles. We manufacture an adapter plate that bolts to the output side of this transmission, giving you the same overall length as the 4L60E that is listed above.
