I've got a 03 Jetta 5 speed. I recently picked up a .658 5th gear swap and installed it. Got new fluid in, put back together, and took it out for a drive. I get the noise heard in the video. Everything shifts fine, everything feels smooth, ran through all the gears. 4th gear is probably the quietest, 3rd gear is the loudest. One thing I did not do was get an exact torque on the end bolts for the gears, but had gotten them pressed on the shaft completely. Has anyone experienced the same or has any ideas? Theres no break in period on these gears until they quiet up? They are cascade german gears.
