Built RE4R03A and RE4R01a,,,these are the two automatics for the Z32 twinturbo and NA. These transmissions are built to last .. built way beyond stock specs.. Cases are machined to handle higher pressures, valvebodies are built to hold higher pressure and shift harder between 1 and 2nd and 2nd and 3rd . Extra frictions and steels added to handle added horsepower. and more We have several of these built transmissions in the US and Europe.
