THE Transmission Thread 2.0, Now with Pictures

[Scargo]

I have a transaxle rebuilding question. I an putting close-ratio fifth and sixth gears in an '04 tranny. I have it apart to the point of the driven gear cluster and the main shaft with gears.
I need to know how I can safely hold the driven shaft gear cluster so I can remove the nut that holds it all together. It requires 400 foot pounds to loosen/tighten the nut. It's not a matter of having or obtaining sockets or wrenches to apply leverage on the nut, but how best to hang onto the gear cluster while I break the nut loose. I only have a 1/2" impact.

EDIT: Nevermind. I sprung for an El Cheapo 3/4" drive impact. I made a punch tool to undo some of the four indentions of the nut's locking ring. Having an assistant hang onto the main shaft with a chain wrench around the the middle of the fifth/sixth gear set, I was able to remove the nut fairly easily. There's still a lot of metal particles scraped off the nut that you need to be aware of as you clean it and proceed with the gear swap.

I'm looking for a rough estimate on the cost for a competent transmission shop to install a Quaife front LSD and replace bearings / seals in the transmission. I need some kind of baseline to compare against some local shops. If anybody has experience with having this done or knows how much it -should- cost, let me know. Thanks!

Does anyone have info on the new manual 6spd tranny that is essentially (I understand) a 6th gear jammed into the 5 speed case? I found a YouTube video about it from Australia, but it wasn't detailed about ratios. There main comment was that it was NOT the same performance tranny as the 6 speed in the STI/Legacy Spec B. http://youtu.be/_L5rmzZJHp8
I'm asking because there is a very low mileage one from a wrecked Forester available in my area. I'm wondering if the case is a direct replacement for the current 5spd, if the current aftermarket LSD's ( Center and Front) will work, and if the gears are at least as strong as the current 5 spd.

Edit: on the Outback forum I found the 2010 6 speed ratios:
2010 Gear Ratios (6MT) - Manual
First Gear 3.454
Second Gear 1.947
Third Gear 1.296
Fourth Gear 0.972
Fifth Gear 0.825
Sixth Gear 0.695
Reverse Gear 3.636
Final Drive Ratio 4.444

Using the gear calculator http://calc.teammfactory.com/ this tranny has better racing ratios than my Legacy GT 5 spd. I spend 90 % of time in 3-4 and these work out even better for the 3-4-5 powerband while still having the top speed.

[Sgt.Gator]

I found this incredibly useful chart at Rallispec. Thanks Rallispec!

"This file provides a means for referencing the original model(s) and gearbox/differential specifications based on the transmission code. It lists gear ratios, transfer gear ratio, final drive ratio, differential types, and some other data. The codes are divided into 4 sections: 6-speed transmissions with 85mm shaft centerline spacing (such as STI), 6-speed transmissions with 75mm centerline spacing (such as newer Legacy manual transmissions), 5-speed transmissions from turbo models (such as WRX), and 5-speed transmissions from normally aspirated models. Only all wheel drive transmissions from Impreza, Legacy, Baja, Forester, and Saab 9-2X models are listed at this time."

So now the CVT with paddle shifter is available. Anyone playing with that yet? 6 instant shifts in manual mode.
Holds back an impreza speeding downhill in the lower gears. Infinite ratio by wire. If you can break the code and fit the box it auto be fun...
This forum is excellent by the way. Obviously I missed the section for dummies

[Scargo]

A WIKI on using the CVT manually states, "Keep in mind that the long-term effects of downshifting on a CVT transmission are unknown."
I can't imagine it would be applicable to use in a race car. I could be wrong, but I doubt it is built to take that kind of use or an increase in horsepower or torque. I'm just guessing.

[erlihemi]

I have no idea if the CVT would even fit the 818 chassis, but, there is good reason, at least in theory, for using one. As far as reliability is concerned the other manufactures are getting miles on them. I've driven some bad ones that "dial down" letting rpms go to high and the car doesn't accelerate. I assume this is bad programming/tuning. Subaru seems to have the tuning part correct. I have a Forester and Impreza with the CVT and I like the manual control on the Impreza with paddle shifters. The forester feels like a lot more torque on the bottom, but its a 2.5 vice 2.0. I only have 3,000mi on the Impreza. Assuming its good for 250hp and at least one season I would be interested in exploring ratio selection mods to the controller or servos. I would also consider a clutch vs. torque converter input (on the 818, not my Impreza).
If it can stand a turbo you could, in theory, program it for boost optimization and keep the engine in its preferred band. It also should be less harsh on the differential and axles. Smooth is fast on some tracks...

[Boog]

I think i'm missing something. If the CVT is capable of holding the torque, why would you use paddle shifters instead of just having it always sit at the RPM that produces max torque (assuming a racing situation)?

[Jaime]

Because the RPM that produces max HP will accelerate better.

[Jaime]

Also, I test drove a CVT Impreza last year. One of the differences between the Impreza and the other CVTs I drove was that the Impreza was "stepless". It didn't attempt to pretend it had gears. I mentioned it to the sales guy and he said that might be the reason a lot of customers say it "drives weird".

[wleehendrick]

Nissan CVTs (at least the Altima rental I drove) and a lot of hybrids also drive 'weird' in that they hold a constant RPM while accelerating, no simulated shifts. This makes perfect sense given the technology, but feels and sounds so awkward. Its all in the programming and customer expectations.

IMHO, paddle shifters or simulated ratios are a silly anachronism on a CVT, about as useful as a screen door on a submarine! For the street, you want max economy, which generally means the lowest RPM that delivers the required power. For the track, you'd want it to be at the power peak all the time like Jamie said.

It took a long time for manufactuers to get CVTs to handle decent torque, and theyre generally not the enthusiast option, so I would be really worried to bolt one to a tuned turbo mill and drive it agressively.

[Boog]

Because the RPM that produces max HP will accelerate better.

Ok, max HP then.

Sounds like the tech isn't ready yet, and drivers don't like the feel?

[Jaime]

Hydraulic CVTs have been available forever and can handle pretty much any load, but they are too heavy for small cars.

A good CVT in a sports car would need really good software to make it fast. I don't think a kit car is great plaform to make it happen. Alternately, it could be manually controlled, but that would negate a lot of the benefits.

[erlihemi]

If I had realized this much discussion would be generated I would have started a separate thread. I'm just a rogue hotrod guy dipping my toe in the flat four world. That said I've seen a lot of gearboxes of many vintages and applications including ones I could crawl through. I have to agree with Jaime in that much work of questionable reward is likely with the CVT. I personally would go electric before CVT. But then that's been accomplished. So if anyone wants to grab a wreck and play with the CVT please share the results with us. CVT's do have potential, my XUV gator proves it, my wife's jeep compass did not, Subaru is using it on the NA motors, we'll see...

Internals shinier than stock....

[Scargo]

I wonder how that jewelry-looking chain will handle 450 FPT of track abuse?

[erlihemi]

I just remember everyone saying the same thing about those "chain drive" transfer cases. Well, a lot of them survived and they don't try to push the case apart either. Surface contact area on those cones is probably greater than the 4 gear teeth on that 5 speed...

[Sgt.Gator]

If a CVT gave an advantage you would see them in Nissan NISMO race cars and GTRs, and every other manufacturer who sells CVTs in street cars would use them in their race cars. Even if they were 90% as good as a sequential tranny or a double clutch tranny they would use them for marketing purposes. None as far as I know do that.
That's a good enough reason for me!

Williams/David Coulthard tested one in 1993 in their legendary F1 car. It was several SECONDS faster. That is outrageous considering MacLaren reportedly spent $100million in 3 months to close a 0.5s gap one season. The CVT was banned by two separate rules for good measure for 1994.

[Evan78]

For racing purposes, wouldn't the ideal transmission keep the engine at the peak horsepower RPM as much as possible and have no time lost to changing gear ratios? That sure sounds like a CVT to me. I guess it's harder or more expensive to execute than to type out on my keyboard.

[RetroRacing]

I don't know of a sanctioning body that allows automatic transmissions, which is what a CVT really is, and yes, it is the best way to keep the car at peak power. I don't know the parasitic loss percentage, but I would think that would be better as well.

[Sgt.Gator]

In ICSCC Pro 3 automatic transmissions are specifically allowed. So the ICSCC conference rules have no prohibition on automatics. Then you have to look at individual class rules.
ICSCC ST class is totally based on HP/Weight ratio. The only mention of transmissions is that an H pattern syncromesh tranny gets a bonus weight reduction factor. Under ST rules it seems that an automatic would be legal, but an 818 is not because the class does not allow tube frame cars.
ICSCC SPU-M-O classes have no rule against an automatic. SPM is where I will race an 818 when I build it.

But this is all just theory in an 818 because I doubt it's possible to convert any Subaru automatic transmission to front wheel drive only (rear wheel in an 818). If it is possible it would make it a lot easier to tune a 3.0 - 3.6 since the Subaru USDM ECU for those engines is only for an automatic tranny car. You could tune them with RomRaider. You wouldn't need an aftermarket ECU unless you also turbocharged it.

I'm sooooo confused!

You and me both. or should I say, Join the club?

[JB91710]

You and me both. or should I say, Join the club?

For my 07 EZ30 I have found out that the strongest 5 speed box should be the 05-06 legacy GT. I will have to install a limited slip down the road if I want one. If I want a 6 speed, I'm not sure which one is strongest and it has to bolt up to the EZ30. This trans has the LS so that's good. The FF end plate and gear shift hardware has to work also or it has to be available somewhere because I can't fabricate it.

Any ideas on which 6 speed is my best bet?

Thanks,

Jack

[Ipassgas]

Since some of the first page pics are gone, I just want to verify the Phase 1 vs Phase 2.

This is Phase 1 with the diff oiling
phase 1 5MT.jpg

And this is Phase 2 with the 5th gear oiling
Phase2 5MT.jpg

Am I correct?
