Note: Please check your transfer case input spline, to suit this kit it must be 24 spline.
The transfer case adaptor housing replaces the automatic transmission extension housing. The adaptor housing then fits to the transfer case using the original Nissan bolts. The housing has mounting provision for the 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.
The output shaft in the kit is supplied on an exchange basis. If your shaft is not supplied with the original order a deposit of $110 will be charged. Change over shafts that are pitted, rusted or heat damaged will not be accepted. The deposit will be refunded when a suitable shaft is received at our factory. Postage or freight is the responsibility of the sender.
TH700 and 4L60-E
The 700R-4 is a GM 4-speed overdrive automatic transmission that was first introduced in the US in 1982. Unfortunately the transmission developed a bad reputation, as early models were prone to failures. GM redesigned the 700R-4 in 1985 and a larger sprag was introduced in 1987.
The 700R-4 was available in two different case variations. The standard GM V8 version will bolt directly to the Chevy V8 petrol, Chevy V8 diesel and Turbo pattern Holden 308 engines.
If you intend using a 253 Holden V8 or a Trimatic pattern 308 you would need to adapt the automatic transmission to the engine with an adaptor plate, they are generally available from any speed shop.
The V6 commodore was also fitted with the 700R-4 transmission. The V6 transmission has a different bolt pattern to the V8 version and therefore, will only bolt to a Commodore V6 engine.
The 700R-4 is an excellent choice as an automatic transmission in a 4WD vehicle as it features a low 1st gear, lower than any other GM auto, and an overdrive top gear, ideal for highway cruising.
The 700R-4 has an overall case length of 594 mm and when coupled up to our 155mm adaptor housing gives you an overall transmission length of 749 mm. The 700R-4 has the following gear ratios: (1st 3.06:1), (2nd 1.62:1), (3rd 1:1), (4th 0.70:1).
The 700R-4 utilises a lock up torque converter for improved efficiency. The engine ECM controls the lock up. To perform this operation the ECM requires a speed input from the vehicle speed sensor or VSS.
The Commodore 700R-4 automatic transmission was replaced by the 4L60-E in the 1993 VR model, they then changed the rear housing to a 6 bolt setup during the VT Commodore era. The transmission is electronic and is controlled by the engine management computer.
