I have never had a VB mod, just the DR. But back when I was spraying a 150 shot without the DR mod it would take forever to shift with all the extra power but with it there was no noticeable delay. With the Suprastick and DR Mod its even quicker.

I have only blown one trans about 4 years ago and that was doing a burnout in 4th gear and I hit a patch of prepped track and boom. I only do burnouts in 1st gear now.

 

the only downside that i see having the shifter as the cruise buttons is it will be difficult to shift while turning, say at a track race.

why do you still have the DR mod? i thought allowing the TC to lock up was just as good. is the shift more harsher now?

 

Jim, I'm assuming the shifts with the SupraStick are roughly as quick as the old "shift_fast" some of us experimented with? Those shifts were FAST. I still to this day can't believe my 140k mile conventional auto tranny could shift THAT fast.

 

Locking up the torque converter and having full line pressure in the transmission are two very different things with totally different results.

 

let me ask u question jim, how come the shifts with the suprastick are quickers? Is it because the stock TCM has a slower reaction time between shifts?

 

Well its like Tatanko said the shifts are about the same as the shiftfast mod because you are taking the stock TCM out of the picture. The DR mod works quite well but combined with eliminating the slow shifting TCM its even faster. The stock TCM is designed to shift slow and personally I don't have a problem the way it shifts when I am on the street, but on the track I want the shifts as fast as possible. I think locking up the converter between shifts will make it even faster but I'm not sure if the tranny can take it. I'm still tuning my engine so not playing with the Suprastick anymore until my tune is the way I want it. I have another race this Sun and the next so I need to concentrate on consistency right now.

Last Sun I made 10 runs and all were less than .1 difference which is why I won. I think I can do even better than that with my new setup. Once I get the a/f, timing etc setup I am going to install my V-Manage and do some more tuning as well as playing with the lockup feature.

 

Another quick question-can you still use the stock gated shifter? I really wouldn't want to use the cruise control buttons because I make several road trips a year and need to keep my cruise working properly.

 

4th gens don't have a gated shifter

 

Spent the day tuning and I forgot how fast this car is. I have been taking off in second gear to tune and I forgot once and left it in 1st, torgue steer whips the wheel right out of my hands, scary sheit, can't wait until the race tomorrow. Next week I hope to install and tune the V-Manage which should improve the bottom end even more. I love the Suprastick display, nice to know what gear you are in. I know I'm like a kid with a new toy, I thought excitement was over when I hit 60.

 

The V-manage is to tune the cam timing correct? MORE low end power? Will the tranny be able to handle it?

 

It better I have plans of a 150-200 shot of spay on top of that sometime before the end of the year. I am having so much fun N/A that its hard to get excited about nitrous though.

 

ever since you installed this, i can't stop thinking about it!

who else is planning on getting this?

 

Given that it's not that expensive, easy to install (relatively), and has the option for external controls for shifting, I probably will.

 

I ordered mine a couple days ago SO Jime i apologize ahead of time for any questions i will shoot your way

 

I will be placing my order within a week. already got wiring setup since i did shiftfast mod in the past, so im ready.

 

well i prob won't get this until near the end of May if all works well.

yeh, sorry to bug you about this again Jime, but whenever you have time and fine tune everything out, please do a write up for this

 

Very neat Jime. Real trailblazing.

What I really love is the LCD display, the use of the cruse controls for down and up shifts, and the ability to set shifts based on speed. Very neat...

 

I have a 5.5 gen. Regardless, can you still use the stock shifter and get the Suprastick to work properly?

 

I know, I thought you were implying he had a gated shifter on his car, which is a 4th gen. My bad.

 

The "gated" shifter is nothing more than a fancy way to activate the "3" gear of the 4AT. Position "3" actually does not move the linkage physically, it depresses a microswitch that activates "3"rd gear, when you move between D and 2 then you are moving the linkage again. The sideways motion from D to 3 is just for that microswitch. I have the 5.5 gen AT in my 4 gen using the 4 gen shifter. I use the O/D ON-OFF switch to activate "3" in my car. So, I suppose the Suprastick would work fine.

 

Congratulations again for this sick discovery,had a hard time comptemplating a 6spd tranny swap for $2500-3000 (even tho it prolly b worth it to me)but this is the perfect solution.I really want to get this mod but i in no way shape or form am going to attempt to install this mod,so do u have any suggestions on where i might b able to go and have this professionally installed? thanks in advance.peace

 

why can't you do it yourself? its just a couple wires and a little programming

 

Why were you thinking of a 6-speed swap and changed your mind to using the SupraStick? That's not even remotely the close to being comparable.

 

Still wondering if you can control the shifting via the stock shifter. Also, if left in drive does the transmission still shift by itself or does this mod mean you have to manually shift all the time?

 

As described in the thread, you have two options. to manually shift (with buttons or cruise control) or you can set it for automatic just like stock (using ur new shiftpoints and program

 

I realize that but I also want to know if there is an option to retain the manual shift fuction of the factory shifter.

 

the suprastick won't restrict the use of your factory shifter.
just need to leave the suprastick in the auto mode though while using it.

 

That's what I needed to know.

 

why? i have a modded 02 auto and wanted to add sum fun by being able to shift gears when i want,how aren't they comparable when your taking a car that cant manually shift from the factory and changing it to a car that can shift manually?

 

sounds intense to someone who has only installed a cold air intake w/the help of some of my peoples!Actually all the mods on my car my boys help me with so doing a mod like this on my own kinda got me shook i love my max and dont wanna f*** it up feel me?

 

Damn I just ran into this tonight.. I gotta catch up from page 1 but I wondering if this will work with the 6th gen 5ATs

 

Simple answer: no.

 

Wow great work on this thread

I just did an entire tranny rebuild on my 04 Max with a 5AT (RE5F22A) including modified Torque Converter and entire VB replacement.
http://forums.maxima.org/showthread.php?t=559475

Question, does anyone know where I can get a Transmission Controller that can be used to help boost the transmission pressure when running the track? Any help would be appreciated...

 

That would explain I havent gotten a response for them..

 

It is setup to control a 4-speed and the simple 2 solenoids that control those gears. 5-speeds have more than 2 solenoids, hence why it can't control them. I hope that explains it for you.

 

Anything to your knowledge on the market that can help answer my question from post #193 ???

 

Interesting - you had a modded 5AT built for your car... Wow.. If you download the FSM for the 2004 Maxima, click on the Automatic Transmission section, go to the RE5F22A section, click on the DTC P0745 Pressure Control Solenoid Valve section and look at the "Wiring Diagram - AT - PC/A" section there, it looks like you can disconnect one wire and raise the tranny internal pressure to the max. Kinda like the old DR mod, which does the same thing.

Looks like the are two wires from the TCM that go to the tranny Pressure Control Valve that normally control tranny pressure. Remove one of those wires and see what happens....

"Not responsible for damages"

 

Thanks Bro, my tranny guy mentioned the same thing so seems like all I would need is some sort of switch to open the circuit (verify pressure increases) and race, then close for normal street driving. We will definitely be looking into this, thanks again Bro!!!

And no worries, any work done on my ride has always been my responsibility since I control what is done. It's just good to hear similar feedback from an independent person.

 

I was just making a joke... If you look at the section of the FSM for your 5AT tranny, the logic is there for controlling all shift solenoids. The 4AT uses 2 solenoids and the 5AT seems to use five! A, B, C, D, and E solenoids... As an example, first gear is A=ON, B=ON, C=ON, D=OFF and E=OFF. With this information and a SPST switch in the TCM line mentioned above, you could build a combo 5AT-DR-mod pressure booster and 5AT 5-gear manual shifter for your nice new transmission.

Makes you kinda sweaty just thinking about it....
