==Automatic Transmission==

The [[R31]] Series 1 & 2 vehicles use a 4N71B transmission in the Pintara range, and an E4N71B in the [[:category:Skyline|Skyline]] range. Both transmissions are made by Jatco, and are similar in construction and operation to the L4N71B and E4N71B transmission used in other models; however, they do differ in their features and control methods.

Fitted to the [[:category:Skyline|Skyline]], the E4N71B is fitted with a lock-up torque converter. A lock-up control unit, mounted under the passenger front seat, controls the operation of torque converter lock-up in 3rd and 4th gears, overdrive selection and changes the transmission shift pattern from an economy mode to a power shift mode.

For the [[R31]] Series 3 [[:category:Skyline|Skyline]] range, the Jatco RE4R01A full electronically controlled 4 speed automatic gearbox was used, which also features a torque converter lock-up clutch. A transmission control unit (TCU) is located under the passengers seat, and while it retains the 'powershift' mode of previous models, torque converter clutch lockup is only used in 4th gear.

----

Fitted to the Pintara, the 4N71B has no lock-up torque converter. A kickdown control unit, mounted under the passenger front seat, can over-ride manual kickdown and controls the overdrive (4th gear) function under certain operating conditions.
