Could be foreign objects in the shifter cavity...When I took my shifter out to clean & grease it, I found a butane lighter, some loose cigarettes, a penlight, lots of change, paperclips, and generally junk stuff down there...

Thats what I do these days. I never heard the ZF making the "normal" noise until I found the exhaust system rubbing against metal parts and the new 3.90 gears. A LOT of drone went away and now I hear a bunch of things. Rock & Roll fixed it all.

When sitting in the driver seat, look at the reverse lockout ring on the shifter, you will see a tiny nylon allen set screw in the lockout ring. Make sure it is snug, but do not over tighten.
