I believe there's substantial faulty "assumptions" regarding the "blue and black" tag ZF's. The "true blues" probably only found their way into the '95 & '96 C4's!
The difference is in the transmissions internals and isn't necassarily ID'd by the "color of the tag"! '94 cars have "lift rings" for reverse and are I believe the last of the "black tag" transmissions but the internals are not to be confused with the early 610Nm transmissions.
The build needs to be "confirmed" from the ZF tag ID on the transmissions.
