View Full Version : ZHP 6MT Shifting - Is this Normal?

Just noticed over the past few days that whenever I put the car into either 1st or 2nd, there's kind of a mechanical resistence/notchiness to the action of the transmission...

anyone else have this problem? is this secondary to the 'short-shifter'?

I think so too. I don't have the ZHP but I do have the same 6MT in my 04 330i. I have about 9K miles on the car now and the tranny has loosened up a bit and is less clunky then when new, but I've also gotten much better at operating the car now. For example when the car is cold and I first start driving away slowly while it warms up, the first 3 shifts or so the rpms will take forever to drop when I step on the clutch and I have to adjust the way I use the clutch and shifter, but after a few shifts once I get going the rpms drop normally and then it's business as usuall. I'm pretty close to trying the CDV delete. There is a local independent shop that will remove it for pretty cheap. But yes, the MT does have a very mechanical feel when engaging the gears. Although if I'm shifting at higher rpms and time my shifts perfectly it will snick into gear very easily and smoothly. 1st, 2nd & 3rd have more of a mechanical feel then 4th, 5th and 6th though.

thanks for alleviating some anxiety... i've noticed it when it's been cold only.

what's is the CDV?

Clutch delay valve. Do a search, lot's of people are removing this intrusive piece of crap, for better clutch response! :thumbup:

The first thing I plan to do when I take delivery is ditch the CDV. The 2nd thing is to swap the 'lifetime' trans fluid for Redline D4 ATF. In my 325 it made a huge difference in shifting, especially into 1st or 2nd or when cold.

I've had that in all three E46s I've had. It's a little more exagerated in zhp cars because of the increased effort required by the shorter throw of the lever.

Dunno about yours, but at 10.4K mine loosened up nicely. Yes still get a little mechanical resistance but can do very smooth shifts now. Standard OEM fluid.

I have 22,000 miles. The shifter is VERY smooth now. Hardly any of the notchiness mentioned above--even on cold days. Before 1 out of every 3 shifts from N->1 was notchy, now it is like 1 out of every 7. Shifting is more pleasant than ever. :)

You live in Michigan... wait until below zero weather... second gear changes will become even more heavy.
