Blew my 07' trans...maybe start a club?
4 Attachment(s)
[B][U]Back story:[/U][/B] Bought the car 2-years ago from the dealer with only 20k on the odometer. Didn't even get a mile off the lot, and the brake pedal pressed to the floor. Turned around, went back in and demanded they fix it. The lead tech told me I am "...not used to performance brake calipers" (funny - considering I also drive an 06' Evo IX and VW R32 which both have monster brakes). After convincing him to take a look, the master cylinder was bad.

Fast forward to 55k miles, heard a funny noise like the exhaust was rubbing in the rear. I found that odd considering I have the Kart Boy 15mm hangars. Turns out, my rear diff exploded. Thankfully, SoA covered that.

Now at 67k on the clock, and was coming out of the parking garage at work. Shifted into 2nd heard a loud *clunk* and moving forward, sounded like someone threw a fork in the garbage disposal. I somehow made it home (I work 33-miles away by the way...), drained my trans, and found this little gem on the trans. plug -

Now here is where I sit as of today -

...and here are the goodies either installed or waiting to be installed -


I decided to go with the PAR gear set (1st-gear straight cut and 2-4th are helical) for 2-reasons:[LIST][*]Highly recommended by the gents @ AndrewTech[*]Was available immediately - PPG had a nice wait list[/LIST]
I have scheduled a road-trip this Thursday (September 22nd) to drop off my trans. and hopefully get it rebuilt same day from AndrewTech.

I'm glad that I don't have the busted trans mod. If you start a club that is just sad lol. Thats too quick of a turn around...I kid I kid. Because me and John have waited months at this point. :p Add pics of the trans being taken apart if AndrewTech will allow such things. ;)

I'm happy to be a part of this special club, but insanely jealous that your build is only going to take one day :mad:

But seriously, I hope everything goes according to plan for you. I also hope I get my car back before winter.

pzr2874 09-21-2011 05:38 AM

Ok, let me guess.

Have everyone tow their car to a meeting place and then when it's over, have the tow trucks come back and take em home... hahahaha

I can haz membership ?

BoostinChick 09-21-2011 06:15 AM

If you have a full size trailer you're in!

man_show, what is taking so long with building your trans? I had to call AndrewTech every other day to nail down a day. Not going to travel 3-hours for nothin'!

turmic 09-21-2011 08:12 PM

What held up man_shows build? IAG and they had to wait for the Aussies to send IAG the Albin gears first. So, that is what held him up a bit.

Sandra are you upgrading the front diff or leaving it stock?

man show 09-21-2011 11:41 PM

Yeah, I don't blame you - 3 hours one way is a fairly significant trip.

My issue began on Memorial Day.

When my car broke down, I had it towed straight to IAG that night - they were already closed. I pretty much just dropped it off in their lot and left it there which I'm sure they weren't too terribly happy about. They must have had a number of other cars to finish working on before they could get to mine which probably set me back several weeks right off the bat. When they finally diagnosed my issue as broken 3rd and 4th gears, I opted for a set of Albins helical gears since they're considered to be some of the strongest available and I wanted to minimize the chances of this sort of thing happening again since my next step power-wise will be a bigger turbo. Unfortunately, IAG didn't have a set in stock, so they had to order them directly from Albins in Australia and when they tried to do that, the rep was supposedly out of town. When the gears were finally ordered, Albins must not have had a set ready to ship out (I've been in contact with them directly and they told me it could take up to 8 weeks for them to create a fresh set). The most recent news I heard from IAG was that the gears are currently on their way here, but they still have to travel half way across the world and make it through US customs. After that, IAG has to schedule a timeslot for everything to be put back together. I expect it will be another week or two.

At least I've had about 4 months to save up and prepare for this monster bill :o

BoostinChick 09-22-2011 07:02 PM

Sigh - well customs seems to have f'd me as well. They have been holding up my PAR gear set for the past 2-weeks. My trip wasn't a total waste, I guess. I got to meet with Sam and Andrew from AndrewTech and discuss my concerns and goals. They re-assured me that the reviews I have read about PAR are true, but they have re-designed their gear set and are trying to come back into the market as heavy hitters and I should not be worried. The PAR gear set is rated to hold up to 650bhp which is ~200 over what PPG claims. They showed me a sample gear set compared to my OEM and these things were BEEFY!

Anyway, here are the pics of the destruction. I was somehow able to isolate it so only 2nd gear was jacked like I originally thought -

Case open:

Thats funny because when I talked to PAR they told me what they held torque wise since thats more the problem then HP is.

BoostinChick 09-22-2011 07:18 PM

Hrm - this is directly from their site: [url=]Par-Engineering - Gearsets (Subaru)[/url]

[quote]Subaru 5MT 650hp Synchromesh Engagement - $3,850 AUD (plus GST)

With the advancements in engine tuning technology and increases of modified vehicle's engine outputs rising quickly in power and torque, it became apparent that a new revised gearset would be needed to fulfill the requirement of massive torque capacity, low NVH levels and ease of use for street driven vehicles.

Given a blank sheet to work from, the design and production teams at PAR have used the very latest in design and production technology, techniques and experience to produce a gearset of immense strength and refinement. Boasting the widest gears available to date with 4mm, 3.2mm and 2mm wider gears for 2nd, 3rd and 4th speeds respectively and the refinement of the tried and proven 450bhp 5MT gearset, [B][COLOR="Red"]the new 650bhp 5MT gearset is second to none[/COLOR][/B].

[COLOR="Red"][B]- Rated to 650bhp[/B][/COLOR]
- Large optimised tooth profiles for every gear to provide maximum strength and reliability
- Straight cut 1st gear for minimal thrust loads when launching at full power. This protects the thrust bearings supporting the transmission shafts from the shock loads experienced during hard launches, especially when using puck type and multi-plate/rigid centre clutch assemblies.
- Inclusion of new billet 3rd/4th gear hub (OEM sintered metal hub fractures under large torque applications)
- Needle roller bearings used for 3rd, 4th and 5th gears to maximise efficiency and reliability
- Gearset is a direct fitment into the standard factory transmission
- Addition of an uprated synchromesh engagement 5th gear available for customers with high speed applications

- Synchromesh engagement, helical cut gears (2nd~4th, 1st gear is straight cut)
- Synchromesh engagement, straight cut gears (1st~4th)
- Optional synchromesh engagement, helical cut 5th gear
- 1st: 3.18
- 2nd: 1.92
- 3rd: 1.35
- 4th: 0.97
- 5th: 0.73, 0.82, 0.88, 0.92 (Optional $640 AUD (plus GST))[/quote]

So they have changed there website in the past 2 years. Thats all. I started doing research for mine and they were making claims close to this, but was with torque numbers.

BoostinChick 09-22-2011 07:31 PM

Yea, as I mentioned earlier I was doing research on them when AndrewTech originally suggested these gears to me. All I found were horrible reviews from the 2004-2006 time frame and I started to panic. That's what prompted me to post in man_show's thread. I am hoping it all works out for the best, and the 1-year warranty on parts/labor helps put me at ease.

man show 09-22-2011 08:16 PM

Sweet pics, but my damage was worse than your damage - nana nana na naaa :tease:

When I heard the crunching sound, I knew what it was, got pissed, and kept the pedal to the metal through two gears. If they're gonna break, damn it, they're gonna break bad!

I also now have a new respect for PAR gears.

turmic 09-22-2011 10:00 PM

I'm probably going to be wrong on this....but, how in the h*ll are PPGs only rated to 450bhp? That makes no sense seeing how people way over 400whp are running them and they are running strong on PPGs. Plus, it only makes sense that TQ destroys gears instead of HP. Think about what the main load a transmission faces that would shear teeth of a set of gears. Something that is a measurement of force (TQ) or something that is a measurement of: force x distance / time (HP)? Bah...both include TQ to some degree.

BoostinChick 09-23-2011 09:15 AM

I agree- both vendors list their gears by horsepower rating, not tq. And to confirm, PPG is only rated for 400hp. So I was giving them the benefit of the doubt 450 ;) Maybe they are listing the minimum to play safe?


[quote]Utilising the stock 5th gear, this set increases the power transfer of 1st to 4th gear significantly whilst delivering factory type driveability combined with quiet operation.

PPG manufacture billet selector forks and front LSD's that complement this product as further options

Horsepower Rating: 400 hp[/quote]

PAR lists by brake horse power which measures engine's horsepower before the loss in power caused by the gearbox, alternator, differential, etc. I am guessing the output tq is measured to help determine bhp?

I also had a ~33-mile commute home so I couldn't just beat the piss out of it because I wanted to make it home. I was literally econo-shifting 1st/3rd/5th and babying it all the way back almost in tears.
