That's what she said!

No worries guys... I have been on auto forums since they were email based mailing lists... I knew exactly what type of response I would get posting that on a forum where nobody knows me.

My first couple posts in this thread took place while I was hanging out bored at my gfs bar (she manages) and I may or may not have been looking to start some **** depending on the responses I got :)

so it's all good, and all in good fun, nothing was taken personally.

+1 ***

yay happy ending.

It'll be a happy ending when we get an upgraded transmission mount!

in for the happy ending...

I look forward to hearing about the limitations of the Z, thanks for posting phunk.

Five dolla maka you holla!

I've read to the end of the thread, so I know that the transmission is no longer the topic at hand. But this post interests me.

Can you attribute your 350's transmission longevity to something in particular? In addition to being a DD, my 05 g35 has seen well over 300 passes down the drag strip, in addition to other forms of vehicular entertainment. I haven't been able to powershift 1>2 above 5k rpms for a couple of years now, and I also cannot shift into 6th from any position without grinding.

Did I just get a **** tranny?

^ well over 300 passes + other abuse and you're wondering if its the transmission's fault?

No, those things you can't do are due to the abuse, synchros are probably messed up to hell. The transmission in our cars ins't designed to withstand that much abuse, they aren't race transmissions.

Nor are they designed with a factor of safety of 1 ;)

Not to mention the condition of the shift forks. The OP is a clown, a liar, and a child. Am I making myself clear on this? :happydance:

You get enough wheel spin with normal shifting at redline, why would you want more wheel spin??? Power shifting will equal a slower time...

I will challenge you at this. What stakes do you choose?

You dont do it on cold, wet roads :) In high traction environments it works out fine.

This car has less then 300rwhp... Its not exactly a wheel spin monster.

The only thing I attribute it to is it has been taken well care of in the sense that I am very careful to not grind it. Your 300 passes might be more abuse than my trans has seen... I run decent size/sticky tires on it (currently 305 r888)... but I have less then 20 passes with super sticky tires and drag strip launch attempts. I am pretty lucky that after all these years over 500rwhp that my 3rd gear has not separated yet like it has for many members. However, my synchros are rather great in my 350z with the exception of 5th gear... i get a little "Scratch" into 5th when I shift it quickly.

You could probably credit that my car has had a twin carbon clutch for almost those entire 6 years. The lighter components should help the transmission shift. Normally the ultra lightweight flywheel contributes to helping a quick shift because the engine will decelerate much more quickly... but there is no engine deceleration taking place when you hold the throttle to the floor.

I find it rather humorous that people are so concerned about powershifting.... I would love to see the look on some of your faces if i did it in your car. i hold my right foot on the gas, dead straight on the floor as if i was balancing my body weight on it... i hold my left foot about 1 foot in the air.... just as the rev limit is kicking in, i bruce lee jab-kick the clutch peddle to the floor... some coordinated time after i felt my left foot begin to make contact with the clutch, i begin to yank the shifter with a "no looking back now" effort (cant afford one of those accidental half shifts) and by the time the shifter is done moving my foot has left the clutch and you usually only heard the rev limit bounce once if at all.

If you are drag racing your Z, the only thing that you MIGHT do differently is briefly let off the gas peddle. But when you shift quickly enough, you will start to see that its hardly worth the extra attention when, if you are fast enough, the engine never had a chance to decelerate anyway. The only difference is the little extra grunt when you powershift... shifting hard is what wears out the trans... the difference in wear when i shift hard between letting off the gas or not letting off the gas is negligible... im already doing most the damage... and this is when you DO NOT want to mess up or you might not make it years like I did. I havent focused my automotive career in building transmissions, so perhaps a transmission specialist might say I am putting a lot more wear into them... but from where I stand, its been negligible, as I have yet to break any transmission. So they last long enough for me!

i love my 350z!

currently down for construction :( built a new intake manifold and front mount setup for it... gotta finish the piping then it will be ready for when the snow melts!

What a beautiful Z. :yum:

I'd open the door and give you a gentle shove out at 80mph. jk.

I thought you were ramming gears without using the clutch. What you speak of here is nowhere as bad as that. Youre just flat foot shifting... nothing but wearing out the clutch in this case. Specially if you have a twin plate carbon one which engages more smoothly than a normal clutch would.

Do you DD that 350z?

Wait, are you telling me that I am abusing my car? Seriously? Thanks for the newsflash.

I'm not wondering "if it's the transmission's fault." Obviously my use of the car far exceeds anything any of its constituent components were realistically designed to do. Rather, I was asking phunk what his thoughts were on why his transmission has functioned so well for so long, considering it too has seen abuse.

Like him, I'm talking about full throttle shifting. I use the clutch, I just don't lift off the throttle(except for 1>2). I also have an aftermarket clutch, and a lightweight flywheel, but I'm making half his power(~265whp).

Somewhat on topic - there's a fascinating thread over on the "other site" where the 6mt was torn apart and the internals analyzed. It's no longer a sticky, as it's over three years old now, but if you're interested, it was started by a guy named BriGuyMax. It has picture of the actual individual gears - interesting reading. In fact, phunk posted in that thread.

Fish-slapping at dawn

What kind of clutch is it? Maybe if its a grabbier clutch the shock is putting more stress on the parts..

Different transmissions behave differently and will degrade differently even if put through the same abuse. You know there are minute cracks and imperfections in the pieces from the factory and many more are created over time. Its a matter of putting enough stress on them and parts start to fail. There are an infinite number of factors that could have lead to your issues, an infinite number of different situations. I think its a long shot that you could find a realistic answer to why your tranny broke in 5 years, not in 6.

But, go on. :p

LMAO :roflpuke2::roflpuke2::roflpuke2:

welcome to the forum phunk :tup: im in for products u make

Yes hitting the perfect powershift is great. From years of drag racing it just comes so natural. I will be hitting San Antonio Raceway next month to get some base line runs in.
