2nd and 3rd in Honda trannies are all bad. Synchro issues everywhere. I loved either riding with or launching next to my friend in his RSX-S 'cuz he would misshift 3rd almost every time. You just drop your head in shame :shakes head:

my previous manual trans. cars were a 1999 bmw 328i a 2005 mb c320 and i think the 370z manual transmission is at least the same or better than the trans on both of those cars.

And I think my biggest problem in the RSX was into 2nd. In the Type S, you could run 1st up past 8,000 and still have a good 500 more before redlining BUT, at least half the time you couldn't get it to go into 2nd without a problem--either missing it the first time or grinding.

Just hope I'm not in another car like that. :(

One things are warm shifting is smooth and easy. The firm "speedbump" that the gates cause takes a little getting used to, but it doesn't impede fast shifts. The only issues I had at the track was once instance where I was turning left hard and fast and almost went into 5th. I should not have down shifted into 2nd for the chicane anyways.

This transmission doesn't like uberfast speedshifts anyways.

I guess "uberfast" shifting is up for discussion. When I drove American muscle (in my day), speed shifting on the strip probably was done in a split second, like, maybe quarter of a second. You poised your foot above the clutch and when it was time to shift, you stomped the clutch hard as you shifted to the next gear and took your foot back off as fast as you could. You NEVER lifted your foot off the gas. Like I said, about a quarter of a second. During this time, you moved to the next gear. And, it was always slammed into the gear. Syncros in those days didn't seem to mind.

These days, nothing seems to be made that can shift like that. :(

That's what I'm talking about. The TR3650 in my Mustang handled those shifts just fine, but the Z doesn't like them... you need to lift.

The clutch needs to be depressed maybe 30-40% of the throw to shift. Don't pound it to the floor, you're wasting fractions of seconds. You should still be able to get a shift in roughly half a second.

Lift ? I'm lost... LOL

lift the throttle.

thanks to the fact that we don't have Carbs it's typically better to not just mash the throttle anyways. SRM takes car of your revs.

Well, I never pounded the clutch in the RSX like I mentioned above. And I don't plan on doing it in the Z. After just running up a lot of RPMs and trying to shift fast in the RSX, I began to understand it wasn't going to happen as fast as I wanted to. And, at that point, stomping and raising your foot back off the clutch as fast as possible is a total waste because the shift won't happen that quick in the first place.

I'll shoot for a controlled half-second shift once I'm through break-in.

Hmmm... break-in. 1200 miles minus the 320 I've put on it in two and a half weeks...I should be ready in about another month and a half... LOL

Haha... yeah, unfortunately you need to lift off the throttle when you shift.

Yeah, as I mentioned above, I let up on the gas these days. Thanks for the clarification and info!

powershifting. one of the main reasons why my dc5 had tranny problems. In the manual it says to double clutch for upshift until it warms up, since I read that I do it every time and it works about 80% of the time sometimes the tranny is just too cold and the hammer doesnt seem to want to engage. The gates or whatever they are called seems be less obvious when the tranny is cold as well.

Without grabbing the book and looking, you talking about the Z manual? God knows I've read a bunch of it... LOL

Wonder how many peeps gonna know what a DC5 is here... ;)
