Go put that car on the track and see how long those syncros last. You shift hard they won't last that's y Nissan won't replace the tranny if the see the shavings or little dust particles on the magnet on the tranny. Go take a visit to the drivetrain section and go see how many people are having grinding problems! I put 25000 miles in one year on my car. That's my daily 50 mile commute and my weekend stuff. My first tranny started grinding at 2000 miles off the lot.

^Dyno shootouts and rolling a car into a show does not count as being "pushed"..

Check this vid out of a legit 1000whp+ z doing back-to-back passes at a track and decimating all of the competition. Domestics included..

Can it handle the power yes but can it handle aggressive shifting yes but only for so long.

Watch the video I posted... You may be shocked! :icon17:

What? You do realize that the weak point are the rear axles....
-The 6MT is solid and proven already..

Hal's car is a beast one of the fastest Z's in the country.

It is still I believe to this day the fastest 6 speed,there are other z's that are faster with different transmission though.

Get a hold of dynosty and ask them if theyve never done tranny work in that car then you get that in writting. Eventually you will have to rebuild the tranny if you shift them hard. That car probably sees the track once every couple months. Try to drive that car daily with that kind of power and see what happens. The auto trannys have there own fair share of problems but i guarantee nissan is replacing more manual trannys then auto trannys. none of the cars youve show are a daily driven and weekend warrior track car but guess what mine is and im on tranny number 3. Mabe one of the 3 was a fluke but you cant neglect the fact that im on at least the second one and if you go back on here a few pages people are interested in better syncros because the tranny grind problem is more real then you may know.

hals car is a beast man i definitly give him props for that car but i promise if he starts driving on the track or even drive it hard like a drag strip that car will have problems.

Now can the auto tranny hold up better then the 6mt i really dont know if you read up i said it seems that way because i hear more about the 6mt grind problem then any other tranny problem. I could be wrong i dont really know i can only speek from my own problems and the 150 other members in the louisiana z n g community. All the autos if done correctly with the right supporting mods tend to take the beating more then your human controlled manual transmission.

.... Get it in writing? LMFAO
Hal has had that beast for years! and no, this is not a daily driver.. Good luck DD any car with that amount of HP.

Fact is that the 6mt is proven and solid. You simply need to learn how to shift properly.

Agreed.. Those others are all running purpose built, racing auto trans..

keep doing your research buddy and go buy a high horsepower 370z and drive it daily then you prove me wrong till then I stand my ground. im out.

I don't understand how people want to damn near double the factory hp but don't want any of the risk of damage or failures. 528whp is damn near 600 at the crank , that's allot to ask of all the factory components

I will echo what others have said the weak point in the drive train is the axles. We have implemented a traction control system to help mitigate the shock to the axles before having to go to custom drive shaft shop axles.

Watch any professional driver behind the wheel. You dont see them tearing the sh*t out of the gear box like an idiot. They are clean and smooth on every shift. I model my shifting technique the same way. Look at how dynosty shifts in his other videos. Nice and Smooth. Grinding problems often occur with improper shifting technique.

Been there done that... the G put down more than 550+ at the wheels and we just built the motor for the new owner. We are hoping for 600+rwhp. The transmission has held up GREAT! OS Giken double plate clutch is phenominal as well as their triple plate clutch!
