Default $38 RatioTek Valve Body "Shift" Kit for 4EAT 1998-2007

i dont think the instructions say anything about screens aside from showing their location. i can check mine later though.

what ratiotek comes with is 2 drill bits and u need enlarge some pre-existing holes.

Yeah I see no mention of the little screens in the ratiotek instructions. Just wondering if anyone else had heard/read that ipt and others remove then in our trans and others, and if it might be worthwhile?

If not, anyone happen to know part numbers for the little screens?

its 2 different screens. this is for transmission TV1A4YN1AA in my 2002 WRX. i do not know if they are the same screens for all models of 4EAT. you can check your model/year via the link below.

FILTER ASSEMBLY-AUTO TRANSMISSION FLUID . NO.1 - 31835AA000
FILTER ASSEMBLY-AUTO TRANSMISSION FLUID . NO.2 - 31835AA010

http://parts.subaru.com/a/Subaru_200...11-182-01.html

now that you mention it. its probably good to get new ones since they are $10 and will be right there in front of you. no better time to do it than when the valve body is apart. i'm gonna pick myself up some since my trans build hasnt happened yet.

personally, i would not recommend running the transmission without these screens in place. but im just a dude, not an IPT transmission expert. so untill you get 100% confirmation on that, i would plan on using the filter screens if i were you. and if you do find confirmation on that, plz share with the rest of us.

Do you also happen to know part number of the in-pan pickup screen filter? I always have the hardest time finding anything 'auto trans' lol.
But I would like to replace as much as I can while the pan is off and valvebody out.

just waiting on new internal filter screens for the valve body from the dealership. hopefully soon but i ordered them almost a month ago lol. 15 year old valve body parts take a while i guess.

(small accumulator pistons are not part of the kit)

thats what it is on my 2002. dunno if its the same for you.

work has started on my trans. i'll let you guys know soon how well this kit works. my best "unoiffical" ET was 12.7. i say unofficial because i never made it to the strip sadly. something unrelated broke during testing.

-These kits CAN be used for a 4eat equipped wrx up until 2006, maybe mid tto late 2005 models.
- I have a 2002 wrx which has the Phase 2 Version 1 4eat. This is a VERY important thing to note. Heres why...
-Most people when discussing this topic only mention the phase 1 or phase 2 4eat. I had never heard of the version 1 or version 2 until I did a lot of digging. If you have a phase 2 version 1 4eat then you are in luck. This is the kit you want. The version 2 came in similar year Foresters and possibly Legacy's. The main difference is the version 2 has a different number of pistons(Im in bed but Ill get more accurate info on this very soon).
-IN REGARDS TO THESE KITS SOLD BY RATIOTEK: The only difference between the standard kit and the heavy duty kit are literally a few more washers and extra springs that go inside the springs youd get in the standard kit. I have no way to measure spring rates or Id give them to you so you could find them elsewhere since apparently the HD kit os harder to get.
-I will say this about Ratiotek. It seemed to be a very small outfit because I easily was able to call them and speak to who I think was the owner of the company. He was very no nonsense and was a little impatient with me over the phone but He was very informative and helpful. If you want this kit Id suggest calling them directly. I think its probably a lot easier to get these now.

Also these Ratiotek kits are without a doubt the exact same ones sold by Level 10 for about $160 more. IPT on the other hand supposedly does ,achine work to your valve body and has access to EVERYTHING ELSE youd want to beef up your 4eat, including more heavy duty clutch plates. I have not been able to find any upgrade parts like clutch plates from anywhere. Not even sure where to start.

I really hope this helps guys. Ill chime in again when I find whatever info I had written down or emails etc. If you take anything from this just remember that if you have a USDM WRX with a 4EAT up until late 2005-2006 then youre good. You might even be fine up until 2008 but please do your homework and dont blame me if Im wrong. Im going off of memory here, but my memory is pretty good. If you have a Forester then none of this applies and either way you need to make sure you have a 4EAT PHASE 2 VERSION 1 to use this kit!
Thank you Jackstand Johnny for bringing us this info. Could you further clarify... this kit DOES NOT work with any pre-'98, 4EAT Phase 1 transmissions, is that correct? My '98 Legacy, for example, was built too early for the transition to Phase 2, Version 1, and I suspect this kit is of no use to me.

Or switch it up to a Phase 1 transmission and get a manual valve body with transbrake.....

So:
1. Anyone done the HD or regular kit finally?
2. How does it compare to 600$ IPT?
3. Any DIY TC solutions?

Revive.

Just put in Ratiotek kit(HD).
ITS A MONSTER.

If you send your VB and the kit, we can do it for ~150$.
Also recommend to include the 3 small screen filters and the large one.
If you have new pistons, we'd throw them in.

Also when you pull it make sure:
1. Be careful, it'll spill everywhere. Drain it.
2. Take all silver and two long reamer bolts out.
3. Use a pick to disconnect solenoids, carefully.
4. Use brake cleaner and drain pan. There will be TON of ATF.
5. While VB is away, clean the mating surface with razor blade carefully, or with plastic blade, no care required. Clean the pan as well. Magnet, plug, everything.
6. Get new ATF filter if you want at that time. SoA is 32$ NAPA Gold or similar is 9$.
7. Get a fluid transfer pump for the ATF. It won't be easy(on turbo).
8. It will continue to leak throughout the process, just keep cleaning.
9. When it's all in(18.7 Plug 21mm, 3.8 Pan Bolts 10mm, 5.8 VB Bolts 10mm, lb/ft) fill the 2 gallons in.
10. Test the gears 10 sec in each running. 2x. Check fluid level, it'll be on the bottom of cold. Drive 10 min it'll be probably bottom hot. Should be good. Or measure temps.
11. Profit.

If people want details HOW to DIY I can post it too. I work on Subaru's a lot, but I took a second seat here to the Pro, who've done those on multiple trannies(not Subaru's).

To answer my own question:
1. Yes.
2. It is amazing.
3. Don't need one. Stock is 3300 and unless you have LARGE crazy turbo spooling after 3300 then you don't need it.

I have 2002 Wrx 4eat with 250k with a jdm engine with ~100k mile. I have been tracking the wagon on road courses and i was getting a bit anxious with the transmission having 250k miles and all. I swapped for a “less used” (185k miles) but i read this thread was curious on this ratiotek kit. I ordered the kit and did he upgrade on the less used transmission. I finished swap today I did a test drive and was blown away by how great the car feels. It shifts so much smoother and it revs higher. I feel like i gained an extra 30-50 hp.
I have a leak in the coolant intake hose for the turbo and cannot drive the car until i get this fix. But i cannot wait to send it again.

This thread needs a simple video... no matter how crude it is.

It's very hard to determine how a car shifts just by words alone, it would be great if someone could post a simple video of their tachometer while they drive around. It would probably be hard to imagine how the shift feels, but seeing the tach and hearing how the car sounds would be awesome.

I wish this was available earlier, shift kits usually extend the life of the clutch packs in general. I'd like to know how this kit reacts. Sounds promising.

Kudos to the OP for doing the legwork and research, we all appreciate you sharing your finds!
