The trans brake is putting the transmission in 1st gear and reverse at the same time. I wonder if this could work with the 5AT or if Nissan did something to prevent that from happening.

 

I'd imagine that if you took control of the clutch solenoids, you could do that. But wouldn't it wear out the bands in the transmission really fast since they'd be slipping? Why not put in a high-stall torque converter and hold the car with the brakes?

 

its basically the same thing, just that you would either have to get a TC that has like a 6500 stall (retarded) or it would be a normal TC which is like having the 2-step at like 3500. the trans brake is so you can have a normal stall TC and still launch at like 6500

 

Probably so.....I'm at the point where I'm so tired of trying to figure out a way to make this 5AT work so I can unleash my built motor, that I'm just going to go with a th400

 

oooh a good ole power sucker. the good news is though that it will certainly stand up to the power, the aftermarket is endless and it will certainly help your times

 

Ever think of sticking in a 'Glide?

 

Coach, I'm sure you have posted it, but I'm gonna be lazy and ask; what is your 5AT Tranny setup right now?

 

As a matter of fact, Yes. But I do want to be able to drive it on the highway sometimes and a glide just won't cut it.

My tranny now has a TC and VB upgrade and even with the GTM or SGP upgraded tranny, I wouldn't feel comfortable with it at the power levels I hope to obtain. Plus IMHO I think the upgraded tranny is way over priced. I have a buddy of mine who gave me a th350 so that is another option.

 

FWIW.. the white car is on a nissan 5at. don't know the full details if it has any modfications like valve body or TC..

I sent a PM to the guy who said he knows Tony and asked him to find out what tranny he has, but the guy never got back in touch with me. The car in the vid only shifts to 3rd gear as far as I can tell and then its banging off the limiter at the end of the run. I can't figure that one out!!

 

probly has a 3.1 or 3.3 pumpkin. or maybe its just entirely rebuilt with new gears. or both. 134 is certainly hauling for 3rd gear

 

Have you seen SP's 4l80e? Read some threads about it on supraforum, with great success. Not quite sure if it can work with the Z, but just thought it maybe a possible option.

 

I was with Julian tonight tuning my car and we did some WOT shifts. WOW. The shifts were so much smoother, the ones I didn't miss that is, hehe.
It felt like there was almost no loss in momentum and the lift off and back on the gas bucking associated with regular shifting. I definately have to work on my shifting speed though. I would definately recommend this to those would go to the drag strip or drive on the agressive side.

 

Nice.... my car is @ MRC right now for a turbo kit and while there I ask Julian to Install the WOT box on it....

Did you see my car there? (silver with Volk wheels)

 

Yeah, I want those wheels. After seeing those wheels I've been sort of back in the market for a change in my wheels. Did you get your car back yet?

 

No bro still there It had a exhaust leak and he parts are not here yet...
I want my car back.....

 

Get a new exhaust! I saw up under there... Are you running a catted setup btw?

That WOT box is cool, it would push ME to be harder on the car than I need to be, so I opted not to get it.

 

Hehe... The WOT Box makes shifting easier on the car, not harder... :-) But yeah, it does encourage you to go to WOT more often....

 

So I got a call today from MRC ..... My car is ready to pick up.... Got the turbo installed, WOT box, cant wait to get it...

 

Cool.
Did you get new clutch/flywheel? If you have stock clutch you can enjoy the WOT box right away.
Still waiting to break in my new clutch before I do more WOT shifts.
