Hi everyone, new audi owner in texas and im moving soon and am very concerned, i did a diff flush, and a clutch job, kept old flywheel cause it only had a small burn mark on it, but my rpms in 5th are at 80 are at 5k and i know thats way high, they went down 500 after the clutch to where they are now but was wondering what it could be? It has the typical 1st gear whine as well, dont know if that would affect it. It is a 1998 2.8 30v 5 speed btw
