  Subaru Gearboxes – All you need to know Replacement Subaru Gearbox Choices In today’s automotive gearbox industry there are many terms used to describe repair techniques and consumers are sometimes unsure about exactly what they are getting. Terms like “repaired”, “overhauled” or “reconditioned” or “remanufactured” can be misleading because they mean different things in different workshops and there is no governing body to set and maintain standards. Sometimes this means consumers are worse off than before, because they might have purchased something that either exceeded their needs, or failed to meet them. Consumers have differing needs, in terms of application and budget. They might need a repair for an older car that won’t exceed the value of the car, or they may want a high quality replacement gearbox for a late model vehicle that will give long life and high reliability. Manual Auto CVT Gearbox choices can be confusing. With the many different models Subaru have produced over the years, and the slightly different configurations for specific world regions, there are many things to consider when sourcing a replacement gearbox. It’s not uncommon for consumers to be supplied with an incompatible unit. After making sure that you have identified the right replacement box, there is the question of just how far you want to take the repairs, choices ranging from one or two replacement parts, to a fully remanufactured assembly. At All Drive Subaroo we have worked over many years to design clearly defined levels of gearbox repair or replacement for differing purposes and budgets. Our different gearbox builds cater for all consumers, from those who need to keep an older car going inexpensively, to motorsport enthusiasts who need a gearbox strong enough to withstand high stresses while delivering high reliability. You can choose from the budget rebuilt 5-speed assembled with selected used and new parts, to a fully re-manufactured gearbox as good, or better than the OEM original. We also offer different levels of motorsport gearboxes.

Subaru 6 Speed Conversion

SUBARU 6-speed STI TY856 conversions ADS brings premium power transfer TO WRX, forester and LIBERTY If you’ve got a 5-speed Subaru WRX, Liberty or Forester, especially if you’re interested in using your car in competitive motorsport events, you’re probably aware that the five speed box, although serviceable and easy to use, is not the strongest or best Subaru gearbox around. You might also have heard of the race and rally successes enjoyed by the 6-speed WRX STI, with its quick, strong, close ratio gearbox, and you could be forgiven for feeling a twinge of envy. The 6-speed STI box was designed by Subaru with motorsport in mind. It is by far the best and strongest gearbox Subaru have ever made, and with the highest level of operability. The six-speed gear set is nearly twice the size of the 5-speed and twice as strong. It can easily handle up to 300 Kw of power and a high degree of driver abuse. The six speed box (non-DCCD) was introduced in 2002 in the WRX STI, and revived interest in the Subaru brand. The STI still uses the 6-speed box, but since 2003, in DCCD version. Subaru are aware that in some ways this gearbox is the centrepiece of their premium performance models, and have invested considerable time and money into ongoing research and development. The six-speed DCCD gearbox has gone from strength to strength and has no known issues. The only problem is that this excellent gearbox only came in STI models, and if you wanted a super-strong competitive gearbox for your WRX, Forester GT/GX or Liberty GT, you had to turn to third party gear manufacturers. Fortunately, it is relatively easy to retrofit the larger, stronger STI 6-speed gearbox to any of the 5-speed models, making it an ideal upgrade. However, there are some complicating internal factors, such as final drive ratios, and some DCCD issues. All Drive Subaru have spent considerable time researching solutions to these problems, and have come up with appropriate proprietary procedures and modifications to make the 6-speed gearbox work smoothly in your 5-speed model Subaru. The result is a kit to retrofit standard STI TY856 boxes to 5-speed models, using a fully remanufactured STI 6-speed, DCCD or non-DCCD, that will bolt straight into your WRX, Liberty GT or Forester GT/XT. All these transmission numbers start with TY856. Subsequent numbers identify which specific components are in the...

Centre Differential

Subaru Viscous Coupling or Centre Differential The unique principles governing the viscous coupling The essential character of the Subaru is in its unique symmetrical All Wheel Drive (AWD) system. With its flat boxer engine set back over the front wheels, Subaru have achieved a 50-50 weight distribution, the same balance as a Formula 1 race car. Combine that with power being distributed to all four wheels, and the ability to vary torque output from front to rear and back to compensate for wheel spin, and you have just about the most poised and satisfying production car on the road, below $100,000. Literally at the center of the AWD system is the viscous coupling, a compact device fitted to the rear of the gearbox in all manual AWD Subarus. A viscous coupling in the simplest terms is a device for transferring torque from a spinning transmission shaft to the front and rear differentials of your Subaru. It serves also to vary the torque between front and rear wheels, depending on driving conditions. Basically the viscous coupling is a sealed steel cylinder containing a number of slotted disks immersed in highly viscous liquid silicon. Power is transferred from the input shaft via the silicon fluid and disks to the output shafts front and rear. When front or rear wheels spin under power, say, on a wet road, the corresponding output shaft will spin faster, generating more heat at its end, which causes the silicon to solidify and prevent torque from being transferred to the spinning wheels. By default, power is redirected proportionately to the other two drive wheels. The silicon is very sensitive to temperature and reliquefies almost instantly once the temperature drops. The system works so well that the driver is usually unaware of it. False assumptions about the viscous coupling Given the power produced by turbo charged engines in Subarus like the WRX, STI, and Liberty GT, it’s clear that this relatively small component has to work very hard, and it seems unsurprising that there have been a high number of viscous failures over the years, sometimes at quite low kilometres. It’s easy to conclude that the viscous coupling must be a weak link in the AWD chain. But that would be a wrong conclusion. Power is not the culprit. In fact there are more failures of viscous couplings in non-turbo models and they are caused by surprisingly minor things,...

Subaru Reverse Drive

Subaru Reverse Drive Transmission The Problem When Ferdinand Porsche was asked to design a utilitarian “People’s car”, he could not have guessed how wildly successful the Volkswagen beetle, and its commercial variant, the Kombi, would become, or the passion they would generate among enthusiasts, who are now using these vehicles in ways the manufacturer could never have envisaged. Some of them are being raced and rallied, some have been converted into mobile homes, and some have been lovingly restored for the concourse show circuit. But under stresses they were never designed to handle , the old engine and transmission set ups just haven’t been strong or reliable enough. The older VW “dak daks” use a boxer style engine, rear wheel drive, and have barely enough power in stock form to blow the froth off a cappuccino. This has been a source of frustration for owners of the old VWs, who have been installing more powerful engines or tuning the old ones only to break the old style gearboxes with heartbreaking frequency. The Obstacle An upgraded gearbox seemed to be the answer, but there were few viable options. The VW rear engine bay, designed to accommodate a flat-four engine and transaxle, limited choice of replacement. The obvious candidates were Porsche and Subaru. Porsche is the easiest conversion, and works well, but is prohibitively expensive. That left the modern day Subaru, with its boxer engine, and in the turbo models, enough power to give you whiplash if you’re not braced when the go pedal is pressed, coupled with a gearbox able to handle the power. But the Subaru used a front mounted engine and transaxle, with All Wheel Drive. You have to get rid of the center diff for a start, and even then, if you stuck any powerful engine mated to a modified box from a WRX into the rear of a VW beetle or Kombi, the car might well go like a scalded cat, but backwards. There was simply no manufacturer building modern gearboxes designed for rear-wheel drive cars, other than Porsche. The Inspiration Enter Todd Triebler, AKA “The Problem Solver” Todd Triebler has been a passionate VW man all his adult life, and a keen dune buggy driver, running a Subaru WRX engine in his VW buggy. As with all such conversions though he was constantly breaking gearboxes, and there was no existing box other than the very expensive...

Subaru Performance Gearboxes

  Subaru Motorsport Transmissions Too much power for Stock Gearboxes When Subaru started to produce high performance road sedans like the WRX and STI, with their balanced weight distribution and symmetrical All Wheel Drive, the potential for competitive motorsport applications was immediately recognised. Even in stock form the WRX or STI, with 180 to 200 KW at the flywheel, was a pretty quick sort of car straight off the production line. But drag racing, and rally applications saw tuned engines putting out 500 Kw or more at the wheels, and under this kind of load the stock gearboxes had an expensive habit of breaking, especially in 2nd and 3rd gears. The STI 6-speed boxes were considerably stronger, but still not up to this kind of punishment. All Subaru mass produced gearboxes use helical synchromesh forged gears, which are quiet and easy to operate. However, under the loads imposed by motorsport applications, they are not strong enough. Three ways to build a stronger gearbox Redesigned gear tooth profile: One way is to change the tooth profile from helical to straight cut gears and from synchromesh to “dog engagement” to allow quick shifting at high loads and RPM. This type of gearbox is used without the clutch being disengaged, and typically makes a crunching noise between gears. Shifts are very fast. Bigger, stronger gears: With straight cut profiles gears can be made much larger, and proportionately stronger and with the straight cut design, power is transferred more efficiently. Helical cut gears can also be redesigned and made larger. EN36A Billet steel: The third way is to produce a stronger box by using billet steel to make the gears. The process is complex, but the steel is much stronger. For the strongest possible box, you can make bigger gears, straight or helical cut, using only top quality billet steel, which is where Pfitzner Performance Gearboxes (PPG) have stepped in. New 6 Speed STI Sequencial Transmision New 6 Speed STI Sequencial Transmision High quality PPG Subaru transmission solutions Pfitzner Performance Gearboxes was founded in 2000, and is the fastest growing, most successful automotive gear engineering company in Australia, with an international reputation for strong competition gearboxes for all marques, an impressive string of race wins to their credit, and annual revenue of close to $3 million from 11 employees, selling to specialist niche motorsport markets.
