ACME Transmission 5EAT Rebuild Kits and Clutch Pack Kits


KoukiS14

Recommended Posts

The ACME Transmissions Subaru 5EAT Clutch Pack Kits and Rebuild Kits are built with the best components available for the 5EAT transmission. Premium frictions and steels are used throughout, with additional clutches added to the major clutch packs responsible for transferring power under high loads in forward gears. This results in additional torque capacity and longevity to solve the problems associated with increased power output from modified engines.

 

 

Some quick specs:

 

33% more surface area on input clutch (4th & 5th gears)

60% more surface area on direct clutch (2nd, 3rd, & 4th gears)

25% more surface area on hi/lo/rev with Penultimate (3rd, 4th and 5th gears)

50% more surface area on hi/lo/rev with Pinnacle (3rd, 4th and 5th gears)

50% more surface area on front brake with Pinnacle (3rd and 5th gears)

What’s the difference between the Clutch Pack Kit and the Rebuild Kit?

 

The key difference is that the Rebuild Kit contains the frictions and steels for the reverse, forward, low coast and transfer case clutch packs in addition to the parts contained in the Clutch Pack Kit. Either kit contains a full transmission overhaul kit. An overhaul kit is transmission industry lingo for the soft parts of a trans rebuild kit. The seals, sealing rings, gaskets, o-rings, etc.

 

The Clutch Pack Kit is intended for a healthy, low mileage transmission, specifically where a user might intend to do the install themselves and doesn't have the specialized tools for a full transmission rebuild. The Clutch Pack Kit contains all the parts to freshen up the clutch packs in the front of the transmission, and "overhaul" the remainder of the transmission. The clutch pack kits include a full overhaul kit for the 5EAT. That means all seals, sealing rings, gaskets, etc. that are needed to freshen up the trans. Essentially all soft parts, plus rebuild parts for the front brake and fully assembled input, direct and hi/lo/rev clutch packs. It does not include frictions or steels for any of the other clutch pack sets besides the front brake, input, direct, and hi/lo/rev.

 

The Rebuild Kit is intended for a local shop to fully rebuild the transmission, not just the "front half" which is essentially what the Clutch Pack Kit does. Of course, if an end user is capable and has the correct tools, there's nothing to prevent them from rebuilding their own transmission. I would recommend the Rebuild Kit option if you're capable of doing a full trans rebuild, if a shop is doing the build for you, if the trans isn't currently perfectly healthy, or is over 100,000 miles. The Rebuild Kit contains all the parts to rebuild the transmission. Exceptions would be low wear parts that are typically only replaced as necessary, including bushings, bearings and pump gears. Those parts are available and stocked by ACME Transmission, and can be shipped via expedited means if the parts are found to be necessary. Please contact me for details.

 

What’s the difference between the Pinnacle kit and the Penultimate kit?

 

The Pinnacle Clutch Pack kit is ACME Transmission’s top of the line offering, while the Penultimate kit is just a notch below it. The Pinnacle kit has a 6 pair hi/lo/rev clutch pack with custom thickness, WPC treated steels, whereas the Penultimate kit has a 5 pair hi/lo/rev clutch pack with premium Raybestos steels. The other difference is in the front brake, where the Pinnacle kit has 3 pairs with custom thickness, WPC treated steels, versus the stock 2 pair setup using premium Raybestos steels in the Penultimate. The extra clutch pairs and WPC treated steels in the front brake and hi/lo/rev clutches of the Pinnacle kit provide greater torque capacity and longevity in gears 3 through 5. Since those gears are the most heavily loaded, the Pinnacle kit is the choice for big power cars intending to run at high speeds.

 

With all of that said, a VB upgrade and bronze diff bushings are highly recommended if you don't already have those items. They'll contributed significantly to the longevity and enjoyment of the transmission, and are "since you're there" type items.

 

Note that pricing does not include shipping. Availability is limited at the moment. I'll have a Pinnacle kit available the week of 7/8/13, then I'll be waiting on clutch pack cores as well as a large batch of custom steels before the next kits are ready to go. ETA is roughly before the end of the month.

 

Just so you all know, this is my pet project and side gig. I'm a full time IT consultant by day. I'll do my best to keep the supply of these catching up with demand. Funding is the major issue at the moment, but initial monies are all rolling back into the project for the sake of expansion, so hopefully availability will improve as time goes on.

I've pretty well convinced myself that I'm taking the clutch pack kit out of the equation and offering just the full rebuild kits. There hasn't been much demand, so it's build to order at the moment. Two weeks lead time is probably realistic at the moment. I just moved and I'm settling into new shop space. Once settled in, I hope to keep one or two kits stocked for quick shipment.

So. Time for a long overdue review of the ACME 5eat Pinnacle plus rebuild kit.

 

In addition to the pre- packed piston drum which Adam meticulously fitted up and had machined to allow the maximum possible amount of clutch packs, I also fitted the following:

 

- bronze centre diff bushings from frankster

- hexmods f1 vb

- rebuilt stall Convertor

- all new seals, frictions and steels to rebuild the front half of the box

 

The box is fantastic and nothing short of it. The power is easily and readily transferred without not one bit of slip (confirmed by dyno revs vs power curve when torque was flat).

 

To put this into perspective, before the ACME upgrade, I was slipping in second and third gear as soon as I hit 15-16psi on my setup. And that was running extremely rich and bugger all timing (base tune).

 

The box now holds 500+whp and 27.5psi of boost with absolute ease. No sign of stress or slippage in the actualy transmission at all.

 

In normal Drive mode, the drive is seamlessly smooth as are the shifts. No jerking at all.

 

In manual mode, the shifts are a little crisper in low throttle / load situations, but not brutal.

 

In auto mode (drive) at wot its crisp and firm but not overbearing.

 

In manual mode wot. It is motorbike like shifting. Romraider logs confirm 0.37 seconds first to second and second to third. This must be seen to be believed.

 

Here are some youtube links to how great this box shifts

 

(Note the squirming of tyres and chassis loading you can hear as it comes on full boost in first)

All in all, I absolutely love this transmission and words cannot describe it adequately. Everyone and anyone who has been in this have been absolutely blown away by how it drives and feels. No manual will come close :)

 

Have blown a centre diff by stripping the gears off the output shaft completely, but other than that, no problems. As discussed in the 5eat thread, I've had the centre diff cryo treated and strengthened as much as possible now to avoid any future diff damage at this power/ torque level.

 

A massive thank you to Adam and Climber Dave for their efforts with this, and their ongoing support which is absolutely critical.

 

In case i wasnt clear, this is a fantastic bit of gear guys and anyone with a modified legacy / liberty with a 5eat should jump on this ASAP.

Can't launch as yet as can't get any boost on the Convertor. Have setup antilag and playing with it a little to try and get 10-12psi on the line.

 

This will give me a 1.65-1.7 60 ft time like my old setup and hopefully get me a 10 second slip.

 

Best run on this setup is 13.2 @125.4mph. That's with a 2.8 60 ft time.

 

Previous pb with old setup was 12.1 (1.68 60ft time)

Yeah, the internals are mostly interchangeable amongst the years, so the build kit will work for 2008+ 5EATs.

 

Thx. We need advice, right now we haven't any opportunity to modify our valve body (2008+). But we also want to improve our tranny safety. My car and car of my friend run just 45.000km that is nearly ~30.000 miles. As I understand, it is low milege, right? So we need just clutch kit, yes? Right now my car starts to over 300whp and I really interested in my transmission health.

 

Second part, what is this core? What is that, were it is located? And, are you shure that our "core" the same to legacy core?

 

Thx a lot for a help.

those vids are crazy, was that 20-75 in like 2 seconds? Redline at 8k?

 

Would you mind sharing how much the labor to put in the clutch rebuild kit was?

 

Thanks mate - like I said picture/vid speaks a thousand words as I can't adequately explain in words how much I love this transmission kit

 

Redline is 8400

 

I'm in Australia so costs were "mates rates" by an auto trans specialist friend -

 

$600 aud ($500 odd usd) to pull apart and reinstall clutch kit and centre diff

$700 to remove and refit with 12 litres of full synthetic trans fluid worth $150

$80 to flush old trans fluid from existing lines and cooler

$50 new trans fluid external filter

Yeah, 30,000 miles is low mileage. I've reconsidered selling just the clutch packs though and I'm only going to be offering the full kits. It adds a little to the overall price, but I think if you've got the trans out, you might as well do the full rebuild.

 

The "core" is the three clutch packs that require machining to be refit with extra high capacity clutch pairs. Those would be the input, direct and hi/lo/reverse clutch packs. Those are done on an exchange basis as part of the kit, and the $900 covers the cost of those in case they aren't returned.
