Chevy V8 diesel engines are now being fitted into the Oka 4WD using our adaptor kits, the kits have been designed to allow the fitting of GM engines and automatic transmissions coupled to the extremely strong Nissan GQ, GU transfer case.
The transfer case adaptor allows the GM 4L80-E automatic transmissions to be bolted directly onto the Nissan Patrol transfer case. These kits incorporate a special steel adaptor that rotates the transfer case down on the right hand side by 18 degrees, this angle is required to allow the transfer case front output shaft to fit with a more acceptable drive line angle.
The kits allow you to use the large range of GM V6 and V8 engines, petrol, or diesel in conjunction with the GM automatic transmissions. The transfer case adaptor housing replaces the original extension housing on the automatic transmission. This adaptor housing then mates to the original Nissan Patrol transfer case via the steel rotation plate.
The adaptor housing will suit all GQ and GU Patrol transfer cases including the 4.2 petrol, 4.5 petrol, 4.8 petrol, 4.2 diesel, 3ltr diesel and the RB30 petrol. The housing has been designed to retain the standard Nissan rear transmission mounting, manual hi-low lever, and brackets.
Some modification to the transmission oil pan to clear the front drive shaft may be required
Note: The Hi low linkage and brackets fitted to the factory automatic equipped Patrols will not suit this adaptor kit. We recommended that you use the lever, linkages and lockout plate from a manual vehicle.
