4eat how good?

I was just on the i-club reading all the post about how much the WRX manual transmission sucks, etc. Well, of course, i have a auto. I've heard that the 4eat (or is it e4at) is pretty much bullet proof, at least after the my99 when the torque bind issue was fixed.
Just wondered what you guys thought of the issue?

The 4EAT which is what it is, was used in alot of vehicles, from a ford taraus to mpv minivan. It is essentially a truck transmission. So it is beefy. However there are some things crap out or have issues.
The first gen legacy 4EAT's had problems with producing excess metal shavings. An external filter kit was added. The other weak point with these transmissions is the line pressure. There is a return spring that is behind a valve, which keeps line pressure up during shifts and what not. Over time the spring wears out, and doesn't keep the valve closed and line pressure drops and the transmission basically will destroy itself.
Other major issue with any auto tranny is heat. Addition of a tranny cooler is good idea.
Auto's will hold the power better then manual.
Personally The reason why you have heard of so many WRX manual failures is because the kiddies that get them can't drive a manual tranny worth ****! I'm sure if you go cranking alot more power then maybe you'll have issues. The WRX has had 200+ hp in other countries for several years with no problems.
The driver means alot!
So with that said. Auto will handle alot more power better then manual. However manual is still good if treated properly.

If the engine was out of the car would it be easier?

I am planning on going up to Wa this summer. Goin to drive up, and one of my mom's friends owns a tranny shop. We are goin to redo the valve body and possibly shift kit and such. I will ask as many questions as i can, and try to take pictures. But until I actually do it.....I really don't know.

I've also gotten the same thing from Robert at forced air as well.

The only real differences are termination of different outputs, as in it might have a different shaped plug.

Maybe next time you talk to them you could get some examples? I think a truck with a 4EAT would be kinda kewl hehe

The 4EAT FWD tranny is the same tranny that is in the FWD SVX. I do not know for sure about the AWD version however.

Do you have the name or info on the shift kit?
Posted 23 March 2002 - 10:27 PM
This company sells rebuild kits and also shift kits. The shift kits are made to be installed during a rebuild in order to correct the problems inherent with this transmission. I think the shift kit is actually under the transmisssion name and not subaru.Just look around a bit and im sure you will find it.I remember someone on the BC-BF group mentioning a shift kit that required machining to the valve body to install.I will have to look that up in the archives.
