Low whining sound from undercarriage

There are no "straight cut" gears in any version of the ZF S6-40.

Gears in the early 6-40s have a slightly smaller helix angle and that's why the early transmissions are a little more noisy and have a little higher input torque rating.

A picayune distinction, to be sure, Hib.

Granted, you've got me beat on the vocabulary front. I had to look up the meaning of "picayune".

Nevertheless, Paul, if you knew a bit more about manual transmissions you'd not say that.

I'd like to suggest that when you're making statements about subjects on which you lack accurate information, maybe you should think twice about commenting.

Oh... THIS certainly went off the rails! It isn't going the way I intended! I meant no disrespect, Hib. OK, I'll admit in jest I was just "pokin' the bear" a little, but thought you'd "get that" - that I was really giving you a sort of a "left-handed" compliment.

(edit): Everyone...should think twice before saying stupid, derogatory, and unfounded chit on an open forum. Especially the two of us.

Sorry for the misunderstanding, Hib. (Shoulda taken my meds first.)

Ok. I did misunderstand the context. Sometimes, that happens when we can't see or hear each other, but I'm still smarting from having to go to my dictionary to look up "picayune".

I find that information very interesting....thanks Hib
