The Ultimate Transmission Thread... Brainstorm Ideas Here!

[Stevoh]

Interesting. What is our tranny code again(can't remember)?

Also, I think I mentioned this before, but someone once told me the trannies in the 3, which have the 2.3, have trannies that should fit our cars. So it corresponds with your post ouch.

So would the 2.3 trannies fit?

[FuLcRuM]

I've gotten conflicting info but I believe we have the G5M tranny. I've also heard G25M, but basicly any G series Mazda/Ford tranny has the same guts.

[Jeff_Jeske]

The bottom line is you are stuck with stock gears and OEM sychros. There are many different trannies that share the internals but strength wise we are out of luck.

[joker1254]

i know, i know, this thread is like a zombie that continues to be resurrected, but has anyone even tried to match up our trannys gears with the gears of a mtx75?
i do not believe i have come across any info stating someone attempted this.

[joker1254]

well since this whole deal seems unclear, and i havent found proof of anything (not saying i didnt miss anything) so i went and picked up a mtx75 and a spare pgt tranny for just under 100$ for both this weekend. pulled apart the mtx, but i dont have the right socket for the pgt's. so im gonna get the right sockets and im gonna find out, even if it ends up being just for myself, if the gears really will fit from a mtx75. i tend to have a very retarded schedule so i should hopefully have results sometime this week.

Wow!! Somebody with ambiton to do something!!!

John, be sure to post up comparison pictures of whatever you find

its confirmed... as stated previously, our tranny and the mtx75 are NOT compatible. i expected this, but i had to just see for myself. its no wonder the mtx is so strong, she sheer size of the internals compared to ours is awesome. the simplicity of the mtx is amazing compared to the gtype we have. the case pulls right off, the towers & forks pull right out along with the input/output shafts...which are about the same length. its so simple, like legos. no 32mm and 26mm nuts to undo. all gears are entirely internal...no separated 5th gear. it took notime to pull it apart.

as for the diff's, i thought they were quite similar, but the ring gear is a little bit larger on the mtx. so i measured the distance of the bolts and the bolt holes are the slightest bit too far from eachother...so u cant just swap our ring gear to adapt the mtx diff. darn..it looked promising. not to mention the axles are slightly smaller that ours by about .5mm...that and i didnt even count the splines. o yea and the gears arent able to spin around and fall out like ours as u can see in the one pic. but even tho it didnt help us any, i still give the mtx75 a for design/strength.

now heres some pics.

so there you have it folks. if you guys want some more pics, let me know..i can arrange that.

Which brings back the question of putting the MTX onto a KL. What is the fesability of making an adapter plate and matching everything else up for the guys that want the reliability to make gobs of power?

I am a Capri XR2 guy, helping Joker1254 with all his stuff... (i use a Gtype as well)

The MTX75 bellhousing is larger as far as I can tell than the probe bellhousing. It may be feasable to make an adapter plate, but I am unsure of what is exactly involved in that. It would make the whole assembly a bit wider.

Then you'd also need to make some sort of hybrid axle, which can get pricey real quick when you look at it all

[Franky]

whoa... Love the mtx75.

Bellhousing wise would be the easiest part. The more complicated one is:

Differential, driveshaft size and lenght and number of splines.

I wish I had an MTX in front of me. I'd make the Hybrid 4 sure; I have a shop that specialises in that kind of challenge. They fitted a 300ZX tranny on a 240Sx.

Sigh. What other tranny would "look alike" ours?

[Mr. MX6]

so after going over some 10 pages... it dosnt work....? why is this thread sticky? at least alter the name...

[1995pgtpos]

that is what i was wondering

[Nado2.5LTurbo]

so cant we adapt somthing to work on our engines all this technology and were still jsut throwing rocks. i would jsut hope mself that someone can make a new tranny hell ill spend thousands to get it. i jsut want one thats reliable on power

[Franky]

Nado 2.5L Turbo:

I hand it to you; I'm not too impressed by our tranny.

I'm trying the cryo threatment. If it doesn't work, I have a bell housing I can spare and I'm trying it. I have everything here to install it ouside the car, and measure see if it fits. I still hope the cryo does the trick. A whole lot less compliated.

Cross your fingers....

[Boost-GT]

So does this work or not. im confised. I need to find a way to make my transmision stronger im installing a turbo and dont want my transmission to break any time soon. I dont realy want to spend alot of money but Libertygears can cryo the trany and either do a Pro Shift or Face Plate Upgrade to our Transmission.


PRO SHIFTING
Pro-rings are designed with teeth at an involute, rather than a straight cut: this is a big factor in shifting, and the pro-rings occupy the space from which the brass formerly occupied. You CAN shift up to ten times faster than ever possible before. The pro-rings are made of better steel than the original gear itself. The pro-rings are press fit to your old gear after the synchronizer teeth have been ground off to a precision diameter. After the press fit assembly, the new pro-ring is secured by a special welding process.
IT IS GUARANTEED NEVER TO BREAK LOOSE.
The teeth are equally spaced so as to engage simultaneously and equalize
the shock load. Each modified gear is honed out for additional shaft
clearance. This minimizes the chance for galling.
Pro shifting and face plating serve the same basic purpose, a bigger window for engagement to prevent missed shifts. Neither are synchronized, so they make street driving difficult. Contrary to popular belief, YOU MUST USE THE CLUTCH when shifting with either system. Although it is mechanically possible to shift without the clutch, the shock load of a clutchless shift can cause severe damage to the transmission. We do manufacture a clutchless transmission with a starting price of $7580.00.


FACE PLATING
Face plating is preferred over pro shifting, but it slightly more costly (initially) than pro shifting. In the long run you will find that face plating is more cost effective due to less wear on engagement components.
With pro shifting, as the pro rings wear from normal use, they burr up and require dressing, deburring and/or replacement to maintain smooth shifting.
With face plating, the engagement lugs are on the face of the slider and the lugs also have a much larger contact area, so in the unlikely event that they burr up, it will not affect shift action. Due to the design of the shift lugs they are more durable, so longevity is increased dramatically (about three to four times longer than a pro ring) and there is virtually no chance of popping out of gear making for a much more streetable set up.

PRO-SHIFTING
$75.00 per Gear -- Customer's Core (when applicable)
$33.00 per Slider -- Customer's Core (when applicable)
$195.00 Labor (When complete transmission is sent in)

FACE-PLATING
$75.00 per Gear -- Customer's Core (when applicable)
Slider prices vary -- call for quote
$195.00 Labor (When complete transmission is sent in)

$195.00 Labor + Parts

They also do custom gear ratios. this is a little exspensive but it might be worth it if itll make our transmissions tougher. Im going to see how much it would cost and see what other options there are. Street driving isnt too bad with the face plating I have a TKO 600 With Cryo and face plating in it on my 1995 Ford Mustang Cobra SVT and i was running 500+HP and 500+TQ. the dang engine blew before the Transmission even showed signs of wear. POS ford 2-bolt main block aint worth a damn put too much power to the crank and the main webs cracked.
