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.
