6 speed noise
Looking for help from experienced C4 owners. I'm new to C4s only owning C3s in the past. I recently bought a 92 with 6 speed transmission. When shifting, particuarly at lower rpm, the transmission seems noisy. It's not really a grinding sound, but doesn't sound normal. Although I'm not sure what normal is. Any ideas? Thanks

Re: 6 speed noise (mstanton)
Its normal...nothing to worry about. It has to do with the cut of the gears, I believe that they fixed this problem in the later C4's to lessen the noise. Welcome to C4's

I love the sound of straight cut gears. Every time someone says "what's that whinning noise", I smile and say "it's the transmission. Isn't it great - sounds just like a race car."

The ZF6 in my 77 whines as well. I have asked a number of people and they all said it is perfectly normal, for a while I was afraid the clutch wasn't disengaging/engaging properly but she shifts fine and runs like a champ

My '96 has a pretty noisy 6-speed. Changing the lubricant to Castrol 10W-60 helped somewhat, but I think it's just the nature of the beast. I consider it a fair trade for the robustness of the ZF.

Mine is noisy, and the alum flywheel really makes it loud, especially under 2200 rpm.
