A Solenoid Info and Instructions. No reviews yet Write a Review. Current Stock:. Quantity: Decrease Quantity: Increase Quantity:. Share This Article. Our Part TF. This fits the Subaru valve bodies that have the six solenoid under one hold down plate on the valve body. You would have to buy whole valve body to replace. Common solenoid to fail. When this happens you have binding while turning like you are in 4X4. Other things you need to check are to measure the tire size. If tires are uneven this also can cause this complaint.

It doesn't seem like a ton of people or maybe anyone? First I am going to start with a brief overview of the differences between phases and versions of the 4eat transmission, along with VTD and MPT center diffs, torque converters, and flex plates. There is a ton of wrong information out there on this stuff but this is what I have verified from personal experience, along with trial and error.
The center diff controls how much power goes to the front wheels versus the rear wheels, and Subaru has three main types they use. The first is a "classic" differential that looks like the one in the rear end of any old car. This is only really used in the manual transmission so I won't talk about it further on here. The MPT center diff is the most common and it is a so called multi plate clutch setup. The computer can lock up a clutch pack in it and force a 4WD locked mode if it desires it.
It is easy to tell the difference between a VTD and MPT transmission based on how the center diff housing looks at the back of the trans. The transmission computers are different between a VTD car and an MPT are different as well, although mainly in terms of programming I think. A picture of a VTD center diff. We have the classic 4eat Phase 1 transmission.
This came in all of the SVX cars, along with any automatic 4 speed Subaru before the year It is a partially electronic shifted transmission that uses a dropping resistor for line pressure control and features a brake band for the shift.
There were several changes to the casting of the valve body and some other details like the number of clutch plates and types of seals used inside based on both the year, and the car it went into. I have not been able to get my hands on one of those sadly. I learned this one the hard way.
The torque converter on a phase 1 is also unique and you can't swap them between phase 1 and 2. Same goes for the oil pump extension on the end of the torque converter. Next we have the Phase 2 Version 1 4eat. It came out in and was used in all of the automatic Subaru's until it was slowly phased out in favor of the Version 2 aroundalthough it highly depends on model and its important to check if you are unsure about yours.
It, like the Phase 1, is a partially electronically shifted transmission. It still uses dropping resistors for the line pressure like the Phase 1, but it uses two instead of one. It uses a completely different valve body than the Phase 1 and no parts can transfer over. It also obviously is controlled differently, and the TCU from a Phase 1 will not operate a Phase 2, and the other way around. It ditches the brake band and only uses clutch packs, which in my opinion is a way better design. They also are generally a ton more reliable and can tolerate a lot more power without any issues.
These are visually easy to tell apart from the Phase 1 because they have a spin on filter on the drivers side of the trans aside from the H6 cars which had a cap instead of a filter in its spot Finally we have the Phase 2 Version 2. These are what subaru calls "direct drive" transmission which means the shifts are fully computer controlled.This simply means that your vehicle is equipped with an automatic transmission with four gears.
The gears for the 4EAT are as follows:. This AWD system adjusts power to wheels depending on driving conditions, making it more technically advanced than the AWD system used in manual-equipped vehicles. Is it better or worse for performance? The second difference is the gearing. You need a high stall torque converter.

The use of this mod for owners whom do not consistently drag race is debatable. Some argue that it increases daily drivability; others argue that it does not. This will virtually eliminate turbo-lag and give much better low and mid-range power. You can also add engine management to take full advantage of your modifications to further increase responsiveness and decrease lag.
Although the idea of the best first mod is highly subjective, I, along with many others, feel that an aftermarket exhaust system is the best first modification for the money. This modification greatly decreases turbo-lag, causing the car to perform better in all circumstances.
Both the VF 34 and 39 have decent spool-up, with good mid-range and top end. If you plan on doing short block upgrades and running higher than 18 psi, then we have found the GT30R to the our favorite. Of course, you will also need the necessary supporting mods to run a new turbo. A great deal of research must be done if you decide that a new turbo upgrade is right for you. This is because the 4EAT holds its boost during shifts. I heard that the transmission in the Auto can hold more power than the transmission that is used in the manual.
Is this true? Yes, this is true up to a point. The general consensus is that the 4EAT is a stronger transmission than the 5MT and will last a very long time as long as it is properly maintained and the abuse is kept to the minimum. This need increases if you plan on launching your vehicle or driving it hard on a consistent basis. C an I manually shift the transmission ala Manumatic? Although available as a true manumatic in Japan, the American version of the automatic WRX does not contain that feature.
You may manually select the gears, although there is little purpose as A manually shifting from a stop will not net you better acceleration and B it does put extra stress on your transmission. I manually shift the automatic from a stop frequently and through the gears without any issues. However, the manual functionality of the 4EAT can be useful for proper power delivery when cornering, it can also be used to place the car in a better gear when racing from a roll.
The automatic in the WRX is a lot different than any other automatic that I have driven. Lets review the different gear selections on the automatic gear shifter. The rules are completely different for modded or even lightly modded cars. Please note that the transmission will not automatically upshift while in 1, so when you shift into the next gear, make sure to do so at least RPMs early because of the shifting delay. Please note that the transmission will not automatically upshift, so make sure to shift at least RPM early because of the shifting delay.
Selecting 3 is ideal when you are driving in any situation where you will not be maintaining a constant speed while driving in the city, for example, or climbing a steep grade. By selecting 3, your car will also be much more willing to downshift into 2 when extra power is required, making 3 the Power Gear of the WRX.

Did you get a great deal? Meet your fellow owners in our Owners Clubs. August Whoops, found this here They can most readily be identified by the external ATF oil filter located on the driver's side of the transmission case. Be advised that H6 equipped vehicles use a remotely located ATF oil filter. This filter is located in the Left front fender well area.
