Broken 3rd gear x 3

[mike2225]

Well put me on that list,I have 80k on my tranny and will be in desperate of these gears once my motor is back together and i turn up the boost!

^Just FYI, to all of those who are interested in a PAR setup, I may be offering these in the near future. They will be available as the entire new gearset as well as drop in replacements for our stock 3rd and 4th gears. The latter should cost under $1400 to your door.

sweet let me know when u start selling them.

That would be great! I think that would complete a lot of members builds, for sure it would complete mine. Thanks!

How about doing a bulk buy on the Par gearsets?

I inquired awhile ago and if we get 10 people to go in we get a pretty signifigant discount. I have all the numbers at home but they are even better then these January Sales numbers.

I think all we really need is 3rd and 4th since those are the weakest 2 gears but I'm also interested in just getting the complete set and being done with these crappy trannies.

I also agree with Focus that were gonna have to just break down and get the strait cut gears. Mine is a DD as well but honestly most of my driving is in 5th so as long as we leave that Helical (and don't boost on it) we should be good up to 500+ HP.

There are probably 2 or 3 of us with Probes that would also get in on these if you guys wanna try and do a BB.

If we do the complete 1-4 setup we can also play with our ratio's, I know Id like 1st to be around 3:1

We probably don't NEED the Pinion gear, just 1-4 strait cut with the double syncros and needle bearings. That should be closer to the 3k mark, maybe a tad less if we get 10 people in on it. (thumb)

.. NO, I will NOT be the person who lays under your MP3 to hold the tube up while you pour in new tranny fluid, so that I wind up with my arm dyed bright turquoise again!

 

[505zoom]

Crap. Not what I was hoping to hear.

 

[shane02pro5]

I'm certain the 1-4 set requires the ring gear for the differential since the pinion gear it meshes with is part of the pinion shaft. Maybe I'm wrong but that's what I understood. All this transmission terminology is melting my brain!!

Comes with the ring gear, if you buy the full gear set...

 

[shane02pro5]

In post 66 Fulcrum mentioned not needing to replace the the pinion gear which meshes with the ring gear. Suggesting just dropping in 1-4 gearset with stock LSD and pinion gear.

 

[Focus]

OK, little update. I made a phone call to Gerard from Par-Engineering, he will get on here and help answer some questions that people have...

Hi Shane,

We also have the synchromesh engagement 1st~4th gear set for the Mazda
G-Series gearbox on special this month for $3,420 AUD (Normally $3,800
AUD). Included in the pricing is the input shaft and gears. These
replace the same factory parts inside your transmission.
As an option, we can also supply double synchroniser versions of 3rd and
4th gears so that you can have the very best shifting transmission
available. If your tranmisssion is single synchromesh on 3rd gear, the
std Mazda 2nd gear synchromesh can be used with our 3rd and 4th gears.

There is also an option crown wheel and pinion upgrade kit available for
the FWD transmissions. These come in a number of final drive ratios and
are also on special for $1,210 AUD.

If you order the whole gear set and crown wheel/pinion kit together, the
pricing drops to $4,230 AUD, so you're saving an additional $400 AUD.

These kits are all in stock and ready to go.

Regards,

I am assuming from this earlier post (and emails I've recieved from PAR) that the Pinion and crown are in addition to the 1-4 set. Id be very happy if they are part of it though.

Is the pinion (or crown forget which is which) part of the output shaft or is it pressed on?

 

[Focus]

The pinion is part of the output shaft.

 

[FuLcRuM]

I guess we can just wait for Gerard but the 1-4 set must not come with the output shaft, we just reuse our stock one.

I have chipped a tooth on my crown but that was only cause it picked up bits of 3rd the last time I blew it.

How about if it's dyed pinkish red instead? I no longer use lightweight shockproof. I replaced it with heavyweight shockproof.

 

[spoolintruck]

I am interested in 3rd and 4th, i dont plan on making enough power to hurt anything other than those 2 gears.

Hello from Sydney, Australia

Hi Guys,

As requested, I've just joined your forum to answer some of the questions that you may all have. It's a great community that you all have formed here.

To confirm, here are the options and variants of the G-Series gear sets:

1st~4th dog engagement, straight cut (racing use only)
1st~4th synchromesh engagement, straight cut (Optional helical)
(Stock 5th gear is used with all versions. Billet 5th gear set is available as an option)

Crown wheel and pinion optional (available in a number or ratios including custom)

3rd & 4th gears can be supplied in single and double synchromesh versions
3rd & 4th gears can be supplied in needle roller or std versions
All gears can be supplied in straight cut or helical (optional) versions

All of the options do not attract any extra cost. The only extra cost will be the purchase of new Mazda double synchromesh assemblies if your transmission is single and you choose the double synchromesh gears. We will supply the Mazda part numbers to make it easy.

The only lubricant that we recommend to use with out gear sets is the NEO Synthetic 75w90HD or 75w90RHD gear oil. It's made in the USA and used in all forms of professional upper echelon motorsport. These are a GL5/GL6 API rated lubricants.

I've multi-quoted many of the questions with our response/comments below.

do you guys do shipping for Spain ? it would be a hell of a deal since the Euro its insanely higher than the USA Dollars... i might be interested on buying these to have it when i up the boost and the actual tranny setup im running pops !!!

We ship our products all over the world by normal postal service or UPS for Expedited delivery. If purchased as part of a big group deal, we can drop ship directly to each person, or to a single person for distribution.

yea but dog boxes are the s***

We only every recommend dog engagement gear sets for customers who use their vehicles for racing use only. Some customers like the dog sets for street use, but 95% of normal street drivers will experience accelerated dog wear due to the extremely different shifting techniques required compared to a normal synchromesh engagement transmission.

but, do you need to send then your old tranny ? or how does it works..

We usually supply the parts to replace the OEM items into your transmission. The fitment can usually be performed by any reputable transmission overhaul shop if they have experience overhauling the G-Series. The only technically challenging part is the need to grind the pinion shaft to a set OD for certain gears if you would like to fit the needle roller bearings. We make a large number of variants to suit different customer's requirements.

Does PAR offer any kind of warranty on their gearsets? I'm on tranny #3 now (chewed through GTX gears even) so I need a replacement...

PAR offers a 6 months parts and workmanship warranty. This does not include abusive shifting which may damage stock synchroniser and shifting parts which may in turn damage the gear set.

Straight Cut Gears are no good for a daily driving car, since they make such a loud ass noise, i dont think anyone here wants to hear that noise all day long, just imagine 5th gear on straight cut and a long trip... Its better to have Helical Cut Cryo treated gears i guess..

also whats the point of helical cut gears if they are the same as stock ?

Our straight cut gears have minimal noise due to the precision and minimal backlash set by our production team. As mentioned previously in other posts, The advantage of the straight cut gears is the minimal stress placed on the transmission housing compared to the helical version. We have had many customers rip the end of the transmission housing apart when pushing extreme horse power.

As an option, we can also supply a housing reinforcement kit which slips into the housing and reinforces the bearing retainers/cups. Fitment of this kit requires precision machining of the transmission case on CNC equipment though.

The helical gears we manufacture use a massive tooth profile compared to the stock OEM item. This provides much more strength and torque capability. The only downside is the extra noise generated. The factory item is cut with a very fine profile in order in the interest of NVH and comfort levels. We also use material that is much stronger than the stock items with all parts specially case hardened and shot peened for the best reliability and strength.

how is the engagement on the straight cut? would it be safe to get the PAR gear set with only 3rd & 4th gears being straight and rest helical or is it recomended all the same? Also what are the helical PAR gears rated for?

The PAR 3rd and 4th gear sets can be fitted along side the other stock transmission without any issues. They're designed to exactly fit within the parameters of the factory components that are being replaced.

I'm certain the 1-4 set requires the ring gear for the differential since the pinion gear it meshes with is part of the pinion shaft. Maybe I'm wrong but that's what I understood. All this transmission terminology is melting my brain!!

The 1st~4th gear set can be supplied with and without the crown wheel and pinion option.

Comes with the ring gear, if you buy the full gear set...

The crown wheel and pinion shaft is an optional extra to the base gear set.

Is the pinion (or crown forget which is which) part of the output shaft or is it pressed on?

The pinion shaft is the output shaft. The pinion gear that meshes and drives the differential crown wheel/ring gear is cut into the end of the shaft.

This is the PAR Gearset:

This picture is of the very first generation Mazda G-Series gear sets. They have since been updated with the very latest tooth profiles and many improvements upon the continuing feedback from many of our customers, from both the street and racing community.

Here are photos of the very latest synchromesh engagement gear set version which was just assembled yesterday.
