the 01 legacy (4.11) and the 00 outback (4.44) have a different final drive ratio so the trans will not swap. UNLESS you also swap the matching rear diff.
your power / economy curve will change. you will have about 8% less power at the wheel and get about 8% better fuel economy, IN THEORY. but it will be hard to calculate since the speedo will be off by about 8%. the speedo will show you are driving faster than you actually are.
have you looked here: www.car-part.com ? put in your zip and sort by distance to see what is close. then sort by price and go to the cheap ones and compare. shipping will add about $150 to the cost of a trans.
this will work.I found a tranny for a 2000 outback. This will work with my 2001 outback correct? Sorry i'm just looking for confirmation before i make the purchase!
If the front and rear ratios don't match, the center differential will fail due to excessive slippage. It will start to bind, and since the front and rear axles are trying to spin at different speeds while the center diff is binding, something in the driveline will break (possibly a diff gear, axle, or the center diff itself).If it does turn out someone swapped the rear out with a legacy, what will happen if the final drive ratios are different? Crazy excessive tire wear? Explosions? Black hole?
My drive shaft broke and slapped the back of the bell house extension off and then a pile of gears continued to fall out the back of my car. It was necessary.there is an ID plate on the driver side strut tower under the hood. it will give you the factory ID # for the trans. compare it to both of the ones you have. see if the ''old'' one is a match.
why are you pulling / swapping the trans??
00 - 04 manual trans outbacks, GTs and forester all have the same 3.9 final drive ratio. (mostly larger tires.)
00 - 04 manual trans legacy L, brightons, and low end imprezas (not wrx) all have 4.11 final drive ratio.(mostly smaller tires.)
You have this backwards -there is an ID plate on the driver side strut tower under the hood. it will give you the factory ID # for the trans. compare it to both of the ones you have. see if the ''old'' one is a match.

I'm not asking about what cars came with what gear ratios. I want to know if there is anyway to figure out the final drive ratio from any markings on the rear diff or trans.You have this backwards -
Small tire / base / economy cars have the 3.9 FD (LONG Gearing)
Big tire / Heavy / "sporty cars" have the 4.11 FD (Short Gearing)
Big tire / Heavy +/ "sporty" have the 4.44 FD (oddball 04-05 FXT / baja comes to mind for US)
The short FD (4.11) either offsets the bigger tires & makes Big tire cars drive the same as small tire 3.9 FD cars, OR makes "sporty" small tire cars like N/A L-GTs a bit quicker vs. 3.9FD cars with the SAME ej25 engine (Early Impreza RS's got a Fd change + a displacement increase from 2.2l to 2.5l to get the "sporty" feel).
good catch, thanksYou have this backwards -

I was not answering the question your are asking above in my previous post but I will now -I'm not asking about what cars came with what gear ratios. I want to know if there is anyway to figure out the final drive ratio from any markings on the rear diff or trans.
