I've seen the manual transmission chart posted here, that has all of the gear ratios. I'm wondering if anyone has that info for automatics.. I have an 03 Baja/ manual that needs a differential. A local yard has an 03 legacy/auto, and I'm trying to figure out if the differentials match. the 03 manuals were 4.11. Thanks

I'm finally going to pull the tranny today. based on other threads (like this one: http://www.ultimatesubaru.org/forum/showthread.php?t=56081) I'm betting the differential is screwed. If that is the case, my junkyard replacement should match diff gear ratios, correct? also, I've noted many transmissions have a lower gear ration for 5th gear than my Baja. Would it be as simple as replacing those gears to improve fuel economy? And finally, If i can only find a diff with a different ratio, how would that affect the car? would i need to change the rear diff to match it? Thanks for your help.

differential oil looked good, and clean. u joints felt good too. It is certainly not a tire or exhaust issue. I had the problem before replacing axles. it has just recently become un-drivable. ultimately, I am likely to get a used transmission from a yard, and either pillage it for parts or replace this one altogether. I can't find a yard with baja, so I need to know which (if any) models have similar enough transmissions to be interchangeable. I'll grab some OEM axles while I'm at it.

So many questions. I like it. I'm not sure the brand on the replacement axles, but I'd surprised if they were OEM. The noise started before the replacement, and the new axles did nothing to improve/worsen the noise. I even drove to Michigan and back since then (yes, rattling all the way). The last few weeks it has gotten very bad, making wonder if the cold is affecting the sound or accelerating the deterioration of whatever is bad. I cannot speak to my guy's exp with Subaru. He's an all purpose guy I've been using for years on projects that I can't do. He may be wrong, but certainly not a crook. You all have me thinking about some stuff though, but I need to get under it to answer a few questions. ie, you've got me thinking about u-joints. I do tend to believe it's more in the axles or bearings than the gearbox, since the noise is more consistent with speed than RPMs. I'll climb under it shortly and get a report on u-joints and drainplug.

138k miles. I replaced the axles about 4k ago, along with boots. the knocking happens when the car is moving, and gets more frequent and louder as speed increases. It's worst is when accelerating. It's also getting more pronounced as the weather is getting colder. I think "differential" sounds like what the mechanic told me - I can't find the estimate. I trust his judgment, but don't have the $$$ to pay him to do it. So it's me, with tools and knowledge I don't have. It's going to be a fun project.

I bought this Baja a few years ago. It has an awful noise/knock coming from the transmission, and I'm preparing for a DIY rebuild on a shoestring budget. My experience in a shop comes mostly from rebuilding 350 chevys when i was a kid, and have little experience with trannys/gearboxes/drivetrain. My questions are: How interchangeable are Subaru transmissions? I've noticed there aren't many Bajas in junkyards, and am wondering if I salvaged a gearbox from a Legacy or Forester would work? or even the smaller Impreza? the engine is an EJ251, transmission TY754VCDCA. Thanks.
