Transfer Case Adaptor to suit 4L60E to Toyota Surf V6 5-Speed, 23T (Chain Driven Case)

The transfer case adaptor housing replaces the automatic transmission extension housing. The adaptor housing then fits the transfer case using the original Toyota bolts.

The housing has mounting provision for the Hilux/4-Runner hi/low lever.

The automatic transmission will need to be disassembled. The main output shaft is removed and replaced with one supplied in the adaptor kit. This output shaft has a new spline to connect to the Hilux/4-Runner coupling sleeve found on the main shaft of the 5-speed gearbox. Our kit that replaces the Hilux 4-speed gearbox is supplied with a new coupler sleeve.

The hi-low 4WD-lever housing is simply bolted to the top of the new adaptor housing and emerges through the original hole in the transmission tunnel.
