Default MY90-MY93 FWD Leggy Trans into MY99

So I was sitting at the light and going through the gears. I get into 5th and it gets stuck in there!!! So I had to heavily slip the clutch in 5th gear to get moving. The engine worked hard and I can smell the electronics burning underneth the hood when I got it home.

Reason....possibility of the shaving from the busted 2nd-to-3rd gear syncro or what not making it stuck.

Tempory fix IDEA
Purchase MY90-MY93 FWD tranny at local 'U pull R Parts' yard for $75, hoping that it'll still work well until I can get this tranny built. Looking at spending $100 total on NEW tranny fuild for the 'used' tranny.

I'm broke so this'll have to be the fix. FWD is fine...tire slippage is key to traction.

The my90-MY93 tranny DOES FIT into a my99 EJ block, DOES IT NOT?
I have the exedy stg1 clutch...

Nothing was buring but it smelled like electronics overheating. The engine was working hard starting in 5th gear, that's all. I didn't want to keep slipping it at anythiung higher than 2500rpms, so that's why the engine was working hard.

Thanks for the comfirmation.
What was the deal about the number of bolts? 6 and 8?

The smell was your clutch. Impreza FWD transmissions use a smaller clutch and smaller front driveshaft stubs. I would guess the Legacy fwd to use a smaller clutch also. ANY EJ trans will bolt to ANY EJ engine, # of bolts doesnt matter. Also an awd Legacy transmission will require a Automatic propshaft for use in an Impreza.

The smell wasn't the clutch. It smelt like the electronics or circuits overheating..... but anyway

Smaller clutch? I thought that you'd have to change the clutch only if the engine need it? So that means that the Turbo Legacy of the same year uses a smaller clutch too?

NO.... the fwd trans uses a smaller clutch. Clutches are matched to the transmission, not the engine. The legacy turbo uses a completly different style clutch and the turbo legacy never came with just fwd. The fwd trans is a light duty POS. IF you use the FWD trans you will need to change your clutch.

If you have burning electronics from just starting out in 5th gear then you have alot more serious problems then just your trans

Scoobie Steve:
Are the rear diffs of the Leggy and Impreza the same or not? The whole housing. Would my driveshaft be able to bolt up to the front of a Leggy rear diff?

it will work but you will need

tranny
clutch
flywheel
presure plate
axels
trans mount

it would be 10000x better to find a 5 speed and matching rear diff

=its a bad idea .. don't dry shift any more

Fuji,

I replied to your pm.

As for some of the comments brought up.......

The FWD axles will work just fine in the AWD transmission.....and for that matter are larger then the AWD front axles. The only exception I could see to this is if the 99 had a different axle setup then the older cars, but I highly doubt it.

As for the clutch issue. I can't say for certain about the impreza, but the first gen legacies used the exact same clutch size for AWD & FWD. I can give you the part #'s if you would like.

And the FWD tranny actually IMO is beefier then the AWD tranny. Less parts to send power through. The main shaft sends power directly to the drive pinion shaft, vs the AWD's setup which sends power to the driven shaft which sends it to the center diff & then to the drive pinion shaft & rear extension housing.

I did some research and Legacy777 is correct. The 1st gen legacy FWD uses the same size 8-7/8" disk 24 spine input shaft as an AWD. The FWD impreza trans uses the smaller 7-7/8" disk 21 spine input. I guess this make sense since the Impreza has the smaller 1.8l engine. So just make sure you get the FWD trans out of a legacy and not an Impreza and you will be fine.

^^^ Yup.

Whenever I get around to it, I'll be converting my girlfriend's '91 FWD 4EAT wagon to a AWD 5MT... and I've been told by several people the FWD and AWD transmissions are interchangable.

Alrighty then!
I was reading through and I just noticed that I didn't put in that I was getting a tranny from a Legacy, sorry.

If you have the new style linkage, like I swapped over on my car, you can get the joint piece and put it on the FWD tranny, and it'll work with your shift linkage.
Josh,
Which joint piece are you referring to?

Thanks everyone!

This should be "FuJi K" posting......

Do I have this joint peice on my linkage? OR do I have to purchase it? Is it on the FWD tranny?

The yard I'm going to lets me take the parts out myself, (local U Pull R Parts yard), so if it's on the FWD Leggy, I can get it OR just simply put that 'old' linkage in mine.

Yay, or nay?

okies, I have the tranny dropped out in about 3 hours. Tomorrow I'll be searching for my FWD tranny. I'll be making measurments from engine to tranny mount to assure that I can use my stock tranny cross member.

I took a bunch of pics, but I guess you all know how it looks like anyway...

Update!

Leggy tranny purchased! Leggy tranny fits! We also took the shift linkage and shifter from the Leggy tranny along with the wiring that went to it, AND the FWD tranny mount.

There where things that we had to cross over from the MY99 tranny.
-Spring that pulls clutch lever back (I have pics)
-Speed sensor from cable to electronic (I have pics)
-Two other little sensors that goes on the side of the tranny (I have pics)
-Added my OBD II rear O2 sensor harness to it (I have pics)

I have to relearn how to drive it in FWD mode. Too much torque on start off and I get wheel spin. The gearing is a lot longer and at 5th gear@60mph, I'm spinning at 2350-2400rpms.

We also modified and rewelded the position of the Leggy shifter so it's WAY short in throw AND height (I have pics).

Thanks for the help, Josh!
Now I just have to worry about this...

http://www.mnsubaru.com/images/membe...ylinder1&4.jpg

.....after getting to drive my car for ONLY 15mins. This happened right after a flashing CEL (mis-firing). The engine died on me. It still cranks and starts up fine, no sounds of bents rods or anything.

well...it's been a fun! The mis-firing occured and then the engine died. It'll start up but die for just a few seconds and then chokes and dies. Give it gas and it won't revv up.

I guess I have to not push the car so much...... it's leaking oil out of Cylinder #1 & #4. SO I don't know if it's blown pistons or what... if it is, then it's time for a STi shortblock. If it's not blown then I'd be dissapointed.... I'm actually not upset of this at all. I'm actually happy because I have an excuse for a better block!
