R34 GT-R Vspec ATTESA ETS-PRO Hydraulic Diagram

R34 GT-R Vspec ATTESA ETS-PRO Hydraulic Diagram


The R33 and R34 Nissan Skyline GT-R Vspec have what Nissan calls - A-LSD, or active limited slip differential  The lockup of the differential is controlled by the ATTESA system pump, and a solenoid. I have heard a lot of people say that it can control torque split from side to side however, there is nothing in the circuit hydraulically, or electrically that allows it to do this. It just controls diff lockup.

One hydraulic line to the A-LSD, one to the transfercase. 
R34 A-LSD installed in an R32 GT-R. We called it the R32.4
