Throw in a few codes and some shuddering and you’ve got an AW55-50 party!īut hey, your personal preference is important, right? It may begin as a few hard 3-2 downshifts, maybe a lack of power, maybe even some hunting for gears as you coast down a hill. You’ll get around without much of a thought until that one day when things start to slip internally and your Aisin-Warner transmission begins a little revolution.

So there’s no telling how long you have if you use an incorrect fluid, but the point is made: wrong fluid = damage at some point. Failure to use the correct fluid will cause transmission damage and codes.” “ Note: The friction properties of this transmission fluid are different from other fluids due to the large amount of converter clutch slip. But how many hard shifts and slippage do you think a transmission will take before it decides it’s had enough?Ī quick trip to the AW55-50 section on the Sonnax site lead me to this quip: Will the wrong fluid kill your transmission? Probably not – at least not in the short term. It’s as if engineers who know way more than the average Volvo owner know that this is a special transmission that has very specific needs when it comes to transmission fluid. So, why is the ATF so important in this gearbox? The right fluid, one that meets the JWS3309 specification, is specifically designed for this transmission and contains an additive package that helps the paper friction discs in the transmission and is meant for long change intervals. BONUS: They are a really reliable transmission.They require transmission fluid that meets the JWS3309 specification.

If you’re looking for a common thread among the gearboxes listed in the cars above, there are two that rise to the top of the list: Aisin 6 Speed Manual Transmission These are just two of many different features found across the different versions. And some of the Volvo transmissions have the infamous stop-neutral feature.
For example, the Saturn version is equipped with eight different operating modes (also known as “shift strategies”).

The Aisin AW TF-8# SC series is a 6-speed automatic transmission designed for use in transverse engine applications and produced by Aisin Seiki.It is designed to handle a maximum of 450 N⋅m (331.9 ft⋅lbf) of torque. SHIFT KIT® Valve Body Repair Kit Fits AW TF-80SC, AF40 and AF40-6, AM6 Volvo and Saab GEN1 7-Solenoid VBs Does not fit GEN2 8-Solenoid VBs AW6AX-EL, AY6AX-EL and AY6A-EL. It was very successful and many have asked for more information regarding the newer TF80. About three years ago I wrote a blog about the earlier Aisin Warner aw50/55 Auto gearbox used in the larger 5 cylinder petrol and diesel engines fitted from 1999 until 2005. Neither strong, nor suited to conversions or serious off-road use. Close-ratio first gear and overdrive in fifth gear. The basic AW55-50 is modified for use in a bunch of cars, including:
The 09G can be found in a variety of Volkswagen FWD vehicle platforms produced after 2003.įirst of all, I think it’s important to note that not all AW55-50 gear boxes are created equal. The Aisin-Warner 09G six speed FWD transmission, or TF-60, has increased in popularity and technicians need to become more familiar with all aspects. Between people who just want to save a few bucks on a vital fluid, to those who simply don’t get the fact that there is such a thing as a wrong transmission fluid for your AW55-50, it’s a wonder, possibly a miracle, that there are so many 2.5Ts with the Aisin Warner transmission still on the road.Īisin-Warner 09G Electronics – Anatomy of Shift Controls. If there’s one thing that really grinds my gears (no pun intended) it’s people who don’t take automatic transmission fluid seriously enough. I follow along in a number of online Volvo XC forums (XC90 and XC70 and general Volvo forums) as well as some of the Facebook pages dedicated to XC90 ownership.
