I get the most gear whine in 1st, with some in 2nd.

Years ago, a (non car enthusiast) friend was riding in my '93 6spd &
indicated that she thought the car was poorly built because the
trans would whine in 1st & 2nd. Told her that it was because of the
way the gears were cut on early ZF transmissions -- got a blank stare
back. :)

I never really noticed a whine in 3rd. I'll try to pay more attention next time. Since the gears are all cut the same, I would thing that this is not a problem.

Early model cars with ZF tranny will make more noise due to straighter cut gears, which are stronger over the 94-96 years.

My '89 (first ZF) is loud in just about any gear minus Sixth, but 1st and second are definately the loudest.....I actually thought something was wrong with it when I was looking to buy it.

They make noise in almost all the gears, its just that when you are in 4 and above the road and wind noise is loud enough to cover it up.

Devilfish- Your noise is normal.....

My exhaust covers up any whine the tranny ever made. I seem to remember it would whine in just any gear, but not real loud. Kinda sounded like a jet spinning down when you would come to a stop.

On mine, first is real loud, second a bit less loud, third sounds like a jet spooling for takeoff, and fourth and above seem quiet or are drowned out by other noise.

Whenever somebody makes a comment about the gear whine (especially at low speeds in first gear) I just say "that's because it's a racing transmission, not a weeny silent transmission."

I don't consider it "whine." I consider it "music."
