In this video I interview Jack McGee, Owner of Jacks Transmissions and he discusses the differences between CBA and DBA GT-R GR6 Transmissions. There is a long lasting debate between GT-R owners about the longevity of CBA GR6's vs DBA. Jack discusses 3 differences in the CBA including Clutch Seals, ETS Gear Splines, and Synchro Sleeves. All GT-R owners and potential owners should checkout this video.
