We offer Mark’s 4wd adapter kit to allow you to adapt the GM 4L60E hex bolt to Landcruiser HF2A transfer case. The adapter kit includes an adapter housing, extension housing, coupler shaft, oil seal, fastening hardware, and adapter instructions. This kit is machined to accept the FJ80 transmission mounting rubber. The crossmember mounting holes may need to be slotted to allow it to be moved rearward slightly. The transfer case shifter mounts to the top of the adapter housing. The bracket provided in the kit allows for the HI/LOW lever to come though the original hole.
This assembly is used with the1990-2002 HF2A Transfer Case that was previously used with the Landcruiser automatic transmission.
The adapter kit is designed for exclusive use with a 2wd 4L60E with a non-removable bellhousing. This transmission is identical to the 700R / 4L60 except that it is an electronically controlled transmission. GM manufactures this transmission in two versions. Both of these transmissions use a reluctor ring connected to the GM engine computer for proper shifting points. The first version of this transmission is a mirror image of the 700R, but it requires a reluctor ring. For these kits we adapt around the 2WD version of this transmission. The kits require the use of a stock 2WD output shaft with the stock reluctor ring. You will be required to shorten this shaft as indicated on the instruction sheet provided in your kit.
This housing is drilled and tapped for the stock reluctor ring pickup. The GM sensor for this housing is included in this kit and allows the proper signal to operate your transmission.
