I mean I did 13-13.5 on my stock clutch with fair tuning and less mods then I have now (missing poly bushings and mounts and Illuminas and obviously Fidanza and Par gears and maybe some other stuff I'm forgetting!) and 235 instead of 225

but with all that and my ACT-xtss I think I'll be breaking 13's into high 12's

First and Rev stock on shaft

 

Look at the syncro damage how the stock gear teeth are bending and curving after only a couple of mounths of non-hard driving thank g-d for these stronger PAR parts!!




WOW I love my gf camera it takes such a clear photo even after its compressed




a pic of inside the tran box you can see part of the diff!

 

I have lot of others pics I just don't know how many more I should post

 

...........................................

 

uh oh

 

what dimension is causing the problem?

 

the gears on the input shaft the third inside is too small on the gear and the fourth too big on the inside! The 4th is also splined in the rev direction if that is a problem? I e-mailed them this morning and he called me back right away and told me they will figure out what needs to be done, like re-make the gears and then ship them out! or something!
and there is a ring that doesn't fit in third!

 

I'm so mad that they are off by so little, but enough that they have to be re-made, I just hope its done extremely fast and correctly to cost me as little as possible for this delay and confusion! I already spent lots of money on all this and don't want to spend anymore!
Clutch and Flywheel bolted right on and seem to fit great!

 

Can you take a picture of what you mean when you say "4th is splined in the wrong direction" - do you mean the splines on 4th on the main shaft (counter shaft)?

 

look how all the teeth on the output shaft including the new third are pointing inward and the 4th gear is pointing outward? I haven't found out from Par if thats ok, do you think thats ok?




you can see here more clearly how its the opposite direction:

 

"Mark,

I'm waiting for the engineers to come in this morning. They've were working until very late last night, so they will be in later this morning.

The 4th gear helix angle has been reversed in order to take the load off the shim/thrust washer that it normally thrust on and to minimise stress on the transmission housing.

Once the guys arrive, I'll jump onto them and get them to have a good look at all the photos and parts.

Regards,"

This is quoted from my e-mail right now, thus i guess 4th was reversed for a reason!

 

Thank g-d for the good customer service PAR is providing me with other wise I would have been a much bigger mess than I already am! They contacted me by telephone immediately after my e-mail and he assured me that everything is going to be alright! I'm curious to how fast they can get the new parts fabricated and to fit perfectly? Hope its soon otherwise my mechanic is going to hang me

 

Seems like they are getting the a33 gears in today and are going to copy them i guess with their own teeth style to make sure that they fit perfectly. Just can't wait to get my car on the road to work in my new clutch flywheel and gears so that my cars ready for summer!

 

"We'll be able to modify the 3rd gear to make the bore larger. With the 4th gear which is too big, we'll make up a new sleeve that you can press onto the shaft so that the ID will be perfect."

So i guess they are sending me a new 3rd and a sleeve for fourth to make it fit!

I just hope i get it real soon!!

 

I was just told by them over the phone that they'll have to re-make the 3rd and 4th to fit perfectly instead of just having it done the quick way were it might not work out! So I guess I'm out a car for a little wile and will have to tell my mechanic I'm really sorry!
Now I'm kind of tripping missing my car but i guess its better to have them made properly! and I'm sure they will be quick about it!

 

So exited!!!!!

coming soon for everyone!!!!!!

PAR Helical or Straight cut full billet set for the Nissan Maxima!!!!

no more gtir gears needed!

New set being designed as we speak!

New 1st-4th par Helical or Straight cut gear set with billet gears made to be extra durable for all us maxima lovers who hate our weak 5spd and would love a bulletproof no worry system PAR is going to manufacture a new set for the Nissan maxima at a great price! I'm sure that many of you want a bullet proof 5spd made for your car just like i've always wanted, not like the gtir gear set were its incomplete... and only 3rd and 4th can be replaced, this set that they are making will be complete full functioning and worry free set!

Basically I'm shipping my transmission over there to be copied and made to take the most power possible with durable efficient teeth and shafts, when its finished I will post pictures and prices and let everyone know how to get one! I'll give full report with dyno and pictures, full audio and video for all to see!!

So far what I've seen from PAR gears are a large tooth profile throughout all gears including the 3rd and 4th I already have and the few other sets I've seen! they maintain a perfect look and design with decreasing the number of teeth wile increasing the size and strength of each tooth.

This means great news for those of us who want to let loose with our maximas and never worry about our one big flaw our ****ty 5spd that has 3rd and 4th that love to shed there teeth and 1st and 2nd that like to crack cause of deadly power made by our VQ's and our take offs and some uncalled for wheel hop too!

-so for those that love to really take off and want a bulletproof 5spd with a helical cut style of teeth to reduce noise and increase strength that is what I've always dreamed of and now that they are going to make an entire set for us its really worth it specially with the specialist and high end materials Par is known for!

Can't wait to get the set they are making for the Maxima I'm going to be so much more comfortable driving my car knowing that my 5spd isn't just going to fall to pieces like its done two times before!

I'm so exited!

 

Wow.. that's a long way to ship a tranny. Are they going to eat the cost of that? Any idea how much this gearset will cost?

 

*subscribed*

 

Gear set prices are not definitive but will be posted as soon as production is completed! But its well worth it for a bulletproof 1st-2nd-3rd-4th 3rd-4th slider+hub input shaft with rev teeth and rev idler, plus needle bearings and some other stuff I think? but I will post as soon as I have any info!

But I mean why spend money on new 5spd when Its not strong enough to hold stock power for that long let alone dragging that stock power, so with any mods or increase in power I will recommend this purchase, and fully recommend it when I test it out myself in a couple of weeks! I will post photos with comparisons and lots of details including rebuild time, dyno (before and after)+dyno with tuning (F.A.S.T wide band), 1/4mile time and time difference, audio for any notice in noise of larger straighter teeth, even though I'm sure it wont be noticeable!

I've been told that I'm the first one in north America to have a custom 1st-4th helical PAR Nissan maxima gearbox!! Maybe even the first in the world to have 1st-4th after market strong big tooth profile bullet proof gears in a maxima?

Thus all in the future who would like to stop worrying about our 5spd and have the ability to use our power with no fear will have the option to turn to the first company to build this 1st-4th helical syncro set for the nissan maxima!

After this I can start driving my car, dragging it and even tracking it soon enough, build up the motor run more boost get like 500hp out of it and have even more fun! So far even at the 400hp level its a monster!

 

That is sweet that PAR wants to do a full 1-4 setup - I really like hearing the mention of needle bearings too. If they use needle bearings rather than the crappy oil groove/machined surface design that the stock trans has, that will be a nice step up in longevity as well. No more smearing/spalling of the input/main shaft and the gears that rotate on them. I've had to replace a number of gears and shafts in otherwise fine transmissions because of that. Our trans is the only trans I've ever been inside that features this crap design.

 

**subscribed** im very curious to see how much $ this will be

 

If I were to venture a guess, I'd say probably in the neighborhood of $4500-5000 USD for all 4 gears and the input shaft.

 

Holy ****....unsubscribe.


Kidding....this is the weak link in our cars unfortunately....something must be done.

 

Id just buy a couple trannies from nissan for that much lol .

 

why buy a couple of s.h.i.t 5spd when you soon get one strong bulletproof set and be worry free! But Lets see how much it costs and well they make it first, I'll have lots of info lots of different photos and comparisons with pricing and audio and video clips for everyone once its fabricated and the teeth last an extremely long time even in a dog box so in a syncro set as long as the shifts aren't meant to kill the syncros the gears should last forever!

 

I've been told the needle bearing is equivalently to the stock setup! but I think you know more than me so if you say its better I'm sure it is! But the way I think of it is that they are both real good once the teeth are strengthened!

How is it you damage the shaft? I've never seen that except for that pic in after market gear set post! The Par input shaft has to be extremely strong with or without needle bearing! I think I'd rather without cause it means less parts that can possibly break but I'll know more after some more research and testing!

I'm just very exited to get on the road already, my shipment should arrive in AU some point early this week I hope tue latest! I figure 5-10 business days for manufacturing and treating, and 3 more business days for shipping one day install and then long road trip to break in gently ~500km-1000km slow shifting under 3300rpm to work in clutch and flywheel!

 

I can take some pictures at work next week if you like to illustrate the difference. Needle bearings or not has nothing to do with the strength of the teeth or power handling as we discuss it - it's just about how the gears ride on the shaft. On the input shaft, 3rd and 4th slide onto the shaft and instead of having a real bearing that they spin on the shaft with, they just spin on the shaft itself with a little film of oil preventing metal on metal scrape-age. Contaminents and the very slight rocking of the gear back and forth on the gear cause this oil layer to break down and cause metal on metal contact, wearing out both parts. I've had a number of shafts and gears that I've had to replace in the maxima transmissions I've built because of this design. I think I've seen this problem in 2 or 3 of the 8 or so maxima transmissions that I've put together. By contrast I've taken apart and rebuilt hundreds upon hundreds of DSM and Evo transmissions over the years, and I've never seen a needle bearing failure requiring part replacement.

If PAR does use needle bearings instead of just an oil film design, it will be nothing but good for you. I hope they do. I actually considered modifying my input and main shafts by milling it down and trying to find a needle bearing that would work, but I decided it was too much work and I was in a time crunch. For an actual gear manufacturer who is making custom parts, it'd be a piece of cake, and a worthy one at that.

and I agree with you moose about having a worry free setup. I used to worry every time I shifted my turbo car that I was going to break another 3rd or 4th gear. I couldn't have fun in the car because every WOT made me cringe, even being careful with it (and I was, I didn't shift my turbo car nearly as quickly as I am capable of). There is much to be said for peace of mind. That's why I spent the money I did on my 3rd and 4th gear rather than just spending $200 on stock parts to get my trans back together. It's not worth it to me to save that money and not be able to enjoy the car.

 

thanks good input and info as always! I'm going to try and see if they are going to do needle bearings? or straight to shaft and their reasoning for it! I'm also curious to see those photos? thanks

 

by the way nealoc if u have the gtir 3rd and 4th and you want more when they are finished the new input shaft design you can get it in straight or helical(I think its better) and your ppg gtir gears should slide right on with the new PAR maxima 1st 2nd and input assembly (possibly with needle bearings that fit as well?) Just wait till I get it and they price it and its tested to fit perfectly! with rev teeth and bulletproof 1st and 2nd and stronger input shaft material!

 

My gears are in Australia its only going to be a few days from now!
I'm very exited and can't wait for them to be installed and drive my car worry free! Ahhhhhhhh worry free! Doesn't that sound great!

 

SO I just received some info for those who are interested to know PAR is going to have the price set at proximately;

1st~4th gear synchromesh straight/helical cut gear set - $4,000 AUD

3rd gear synchromesh straight/helical cut set - $900 AUD
4th gear synchromesh straight/helical cut set - $900 AUD

 

They also decided to go with the far superior design made with needle roller bearings!
As I've come to see with a little bit of research on the gear design of our weak 5spd and a little help from my friend Google, I found out that it makes a big difference for our gears to ride on needle bearings rather than directly on the shaft! This bullet proof 1st-4th set is going to make our cars from semi-reliable torque machines to fully dependable monsters!!

 

Hey guys only a few more days till the 1st-4th set is ready and ships out to me! Can't wait for those bulletproof gears to get here and the NEO gear oil I ordered in the mail!!

For the record after doing some online inquiries and using my friend Google for some answers I've come to the conclusion that NEO might be the best gear oil out there!! Its supposed to be like no other, far superior and not that much more expensive!! Check it out yourselves if you don't believe me!

It was recommended to me by transmission specialists at PAR ENGINEERING, they told me its the best!

frickin sweet man.
