RT-2 ZF 6spd MT S650HD, Repeat Jumping out of 2nd


Bruce Chidsey and Reese Blalock interview with Master Rebuilder Jimmy Stephenson of Aamco Center in Lake Park , FL on this repeat issue of a 2nd gear jump out. After a solid rebuild replacing all of the main items along with damaged parts that could cause the original concern of jumping out of 2nd and 4th gear (per Ford nomenclature, would be 3rd and 5th on GM versions). His supplier helped us understand that this was a HD version and the 1/2 slider assembly and 2nd gear components along with a thrust washer are not available aftermarket.
