My auto is still good with a tick over 200rwkw for the past 14months & that's with a sequential manual-auto.
Mike from MV has used one of the SA forum member's cars as a test bed for the RE4R01A & with supporting mods (ie. bigger ATF cooler, shift kit) the stock trans is good for up to 300rwkw (402rwhp).
Are you referring to MV's magic black box? (Electronic shift controller)If it is, it connects to & disables the auto ECU. It permanently makes it like a manual valve body - requiring full-manual shifts. Also, the line pressure needs to be increased for things to shift properly.
