Hey guys, posting this about my buddies 91 SS EJ22T with a 4EAT in it. He got the car off an older guy that drove that car with very little maintenence. Car has ~150k miles on it, turbo does still boost up car has those nice little EJ22T balls like it should.

 

He blew out the high side clutches on the original 3.9 ratio 4EAT so we decided to put in a Forester 4.44 like I did in my SVX. He didnt tell me before hand that his all wheel drive acted up. So I finish the swap (my 4.44 I donated to the cause was a working driving car, spun the rear wheels as I drifted the forester into the shop, so I know the clutch pack and duty C were working)

 

Now for the issues that hes having with it. On flat ground, its 2 wheel drive. You floor it to spool up the awd clutch pack, nothing happens with the rear wheels. If you hold the e-brake (which I dont recommend with an auto while flooring the gas) it will activate the all wheel drive. So will slightly holding the brakes down while accelerating.

 

I've rebuilt a few of the clutch packs/tail shaft housings on 4EATs and I dont remember ever seeing symptoms like he is having. I keep telling him he has to have a body side wiring harness issue, and that its not the transmission because of the fact that the car did the same stuff before I put the 4.44 in the car.

 

Check engine light is on, I dont know if he ever bothered pulling the codes but I'm almost positive its an IAC issue because the car has idle issues occasionally when its cold outside. Speedo cable is snapped, but if I remember right the 4EAT doesnt shift from the speedo reading it shifts from Throttle angle and line pressure of the tranny correct?

 

Someone/Anyone have any advice or places to look I'd appreciate it. Its warmed up, dumped 6 inches of new white fluffy stuff and our local ice track is screaming out names. I'd like to get his awd functioning properly so I can stomp on that EJ22T with my EG33

i would fix the speedo cable. i'm not sure when it matters and when it doesn't but i'm almost positive I've heard of folks having trans issues due to speedo cables. could probably start a thread and ask or google it.

What year Forester did the trans come from?

TCU uses the speed signal from the dash, without that the trans might not shift properly. If you pull TCU codes there is probably one there for VSS. IAC code could be due to the ECU thinking the car is sitting still when you're driving.

Yes, the TCU certainly needs the VSS signal from the speedometer cluster. The second speed sensor is located at the rear of the trans. It needs both of these working to determine if the wheels are slipping. There is an open-loop part of the AWD control, and that's what you are seeing without the VSS. Also, the TCU expects a certain R&P ratio and speedometer drive gear. If these are too far off the TCU might throw a code and refuse to work the AWD clutches.

 

I assume you swapped the rear R&P with a 4.44 unit as well?

on the 95 - 99 legos, if the front speed sensor fails the trans will default to FWD. with no way to compare the front and rear wheel speeds it will not send power to the rear.

 

how ever, having said that it seems at WOT it may over ride that programming. or early 90s are a little different than late 90s.

yah, the speedo cable thing is something that didnt really cross my mind. My SVX uses the electric signal type speedo, so I never had issues with mine.

 

Got my buddy putting the cable in his car now, I should know something soon. I imagine the VSS1 seeing a speed again will prolly fix it.

 

Thanks for the advice guys appreciate it

 

And yes the the gearing is 4.44 in the rear. I put the VLSD carrier in a 4.44 case

and the tranny shifts fine, hold her to the floor and it shifts around 6 grand.

Trans came out of a 98 Forester

 

Oh the things that make me thankful for my 5MT cars.. All though I've never had an issue with my autos either lol. I just hate working on friends cars cuz they are too lazy
