Ban followed by DIAF

 

I am not 100% sure if the 350z's have a drop resistor like maximas do. In the maxima world we basically disconnected the drop resistor at WOT, this increases the line pressure above stock, this in combination with the transgo kit should significantly increase the life and ability for the auto to hold power.

Ofcourse you need the best cooler you can find, I just ordered a tru-cool meant for 40,000lb vehicles. its 8"x22".

Most importantly a synthetic fluid, preferably mobil 1 or amsoil.

I have had mobil 1 for more than 5 years, with a smaller cooler, and drop resistor disconnected at WOT but without the transgo, my auto lasted all this time with 300-400whp(5 years of alot of abuse, track, street, highway, etc..), it had 170+ K miles.

 

*Sigh* Sorry..I showed up late..a little after 1:20. Hope to set up one more time..

 

And THAT'S pretty impressive.

Jmatic as well as s matic are synthetic.

 

I just installed my transgo kit today, and I am really impressed. I should have done this years ago. I have always had a slight delay between shifts, even with full line pressure. with the transgo, shifts are instant, not even a hint of slip or anything. My temps did go up a bit, but "thats expected considering there is more fluid pressure in there" (as stated by David from Transgo).

 

Just put in a bigger trans cooler.

 

On its way in the mail. Tru-Cool 40,000lb

 

With the transgo kit on a turbo boosted car (400-450whp) will it shift fast enough in auto mode so it doesnt hit the rev limiter?

 

At WOT? Not in 1st gear or for that matter any gear where the wheel spins the engine to redline almost instantly. If you have traction, it seems to do just fine, but I've never had traction in 1st (even with R888 305s out back, -1 camber, on wastegate pressure).

EDIT: I should note that I have raised my redline to 7200 rpms.

 

Thanks.

So even with the limit raises to 7200, running R888s you loose tracton and hit the limiter? Even at the drag strip?

 

Yeah if you spin it does not matter how fast the auto will shift, its going to hit the limiter. Thats part reason why I have my automatic shiftpoints lower than stock. at the track with slicks, and now with the VB it should shift instant, so I can get it closer to the limiter without worring about hitting the limiter (specially when I am using the meth injection)

 

How do you lower the shift points?

 

I have a standalone for the tranny, only works with 4sp auto's though. I can program the shiftpoints, program when the TC should lock, basically everything there is to do with an auto. As well as a manual mode, which I have hooked up to the steering wheel, basically "tiptronic". cool stuff.

its called SupraStick

 

^ that's a pretty nifty device to have!

i don't think anyone has cracked the TCM (or whatever its called) for Zs & Gs

 

What makes it harder is the fact that its 5sp. 4sp are much simpler, you only need to get control of two solenoids, each combination of on and off between the two determines a gear.

 

So I installed the Transgo shift kit at the same time as new transmission internals, TC modification for FI and a cooler. Transmission is obviously tighter than before, even on a big car like my FX.

At the end of this week I'm having a 35R turbo setup installed with a built motor and I'm SURE my transmission is still the weak link with goals of around 450whp.

What is the difference between the TransGo shift kit - $275, or the Valve Body upgrade ~ $850?

My understanding is with the mods I have performed, I've given my transmission some extra life, but eventually I'm going to kill it with the kind of power I'm pushing through it.

Would it make sense to do the VB upgrade even after I've had the Transgo shift kit installed?

 

My understanding is the Transgo Shift kit is the valvebody upgrade. Which means you already have it now on your car

 

shift kit = valve body upgrade, its just easier to say shiftkit. Id say the Transgo is all you'll need, specially the HD2 kit, this is just my opinion, you should contact an unbias tranny builder and see what they say, I think some known performance vendors / shops actually use Transgo in their tranny builds.

 

Make sure you put a large trans cooler on it also and you should be ok.
