Valve Body Mods, Giant Leaps Forward!!!

Yes, that link is long story about my experements with 4EAT/5EAT Subaru from 98+ to last VB.

That "increases the fluid flow" is very close. But this VB have line solenoids with feedback and simple orifice drilling in separator plate to line of pistons friction clutches does not bring happiness (i checked it)). I had to dig deeper, change the control valve feedback to quickly increase pressure + move point of shift to the border of fall torque (when ECU rolls back the angle of ignition timing and little closes the throttle). In sum, with the throttle open, shifting is fast with a small jerk.

p.s. Sorry for my english.)

Slightly to 7400. Stock is 7000.

NOt USDM which around 6K or 6.5

so how you raise the shifting point to 7400, as my 5eat shifts at 7000 even if i raised the limiter in the ROM

i have also JDM gt VF48 turbo water meth injection

Just installed one of @%1; valve bodies on my 09 5eat and it is awesome. Shifts are less than half the speed and feel much more confirmed. Currently running flexfuel on a gtx3071 TS and it feels much better than the mushy stock engagement. I know it’s an old thread but just wanted to put it out in the open that there is an option for 08-09 folks!

I must have missed this post, there's finally a vb for 08-09 for real?

So @lvkeith where and how did you get batman's valve mod? As eldrego mentioned, he has very few post on this site, and no links to his product.

If needed, you can find my ads on ebay for 4EAT and 5EAT all gen VB [fast shift valve body].

I found a solution for the second gen of 5EAT [all TG5D*] three years ago. Already made a lot of VB, all work stably, quickly and without problems.

Recently, I post news and videos from car owners with my VB on instagram "bat_transmission".

Hi all,

 

New here and I've got some questions that I'm hoping someone can answer. I've been googling for days and can't seem to get the answers I'm looking for. I recently bought an 08LGT, and it ran perfectly fine until i got it home. Now it's my huge headache. I'm getting a P0705 (transmission range sensor) code and the car is undrivable at this point. Aside from the other issues (exhaust leak and i think the rear gearbox is shot), I'm trying to figure out what i need to fix this code. I've read that this is due to some kind of sensor, but when i try to find this part, it looks like it's something on the outside of the transmission, though I've also read that it's internal to the 5EAT. I can't find anything telling me what kind of transmission is on this car. Is it the 5EAT? If so, it sounds likely that I'll need to replace the valve body in the transmission. The part on subaruparts.com (Automatic Transmission Gear Position Sensor - Subaru (31918AA000) says it's compatible with my car, but says it's a 4 speed auto transmission.... I'm super confused here. Can someone please shed some light for me?

It's going to be a 5EAT transmission.

 

The internal sensor you mention is likely the Turbine 2 sensor, which is located on the valve body inside the transmission. That sensor is not related to the code you have.

 

 

I searched the part number you posted and saw some info for vehicle fitment that might help ease your mind a bit. See the description and the link below...

If you end up replacing the valve body, I have interest in your old one.

This is probably on here already, but Hexmods has a great tutorial with lots of pics for installation of this good kit, but as far as I have researched is only for limited years of the 5EAT.

 

Hope the link to this product is o.k. with this forum. This product works well, but it is a bit of an install without a lot of diy experience.
