Marks 4WD Adaptors have designed an adaptor kit to fit the TH700R-4 4-speed as fitted behind VN, VP and early VR Commodore engines.

The 700R-4 has an overall case length of 594mm/23.4", when coupled to the adaptor housing (115mm/4.5"), this gives an overall length of 709mm/27.9".

The 700R-4 has the following gear ratios: 1st 3.06:1 2nd 1.62:1 3rd 1.00:1 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. The transmission is electronic and is controlled by the engine management computer.

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.

Marks 4WD Adaptors manufacture a Commodore, shifter mounting and display kit to fit all vehicles.

The universal kit consists of a TPS and mounting bracket, digital display and mounting bracket, bolts, screws etc.

The shifter is fitted to the transmission tunnel in the original gear lever position; this enables the original gearlever boot to be used, which makes the installation look very neat and professional. The shifter display can be fitted under the dash or near the shifter. The display indicates the gear positions, which are illuminated green while the actual gear selected is indicated with a red LED next to the relevant gear.

The display is also fitted with a fault indicator light, which is used to show any ECM or PCM problems. This light is also used to read the fault codes making it very easy to diagnose any problems.

The display is also fitted with a Lockup indicator light which is used to show when the torque converter is locked.
