sirtokesalot Posted September 16, 2019 Share Posted September 16, 2019 (edited) will the auto trans from a 2001 outback LL Bean h6 work in a 2001 outback base model with a 2.5? i know id likely have to change the diff too just wondering are they electrically the same and will work.

sirtokesalot Posted September 17, 2019 Author Share Posted September 17, 2019 I do know the 2001 h6 llbean car is not CDC I'm not sure the transmission number the 2 cars are at a friends house where I'll be doing the work. Quote Link to comment Share on other sites More sharing options...
john in KY Posted September 17, 2019 Share Posted September 17, 2019 (edited) My guess is yes except for the difference in final drive ratios. https://www.ultimatesubaru.org/forum/topic/156582-outback-h6-4eat-compatability/ Edited September 17, 2019 by john in KY Quote Link to comment Share on other sites More sharing options...

You're car is currently 4.44. LL Bean is 4.11. So, if you swap to the 4.11 diff to match yes it will. BUT!!!........The taller gearing will make the car feel less powerful off the line, and during hills and towing. It may improve Highway gas mileage as the trade off. Also, the TCU may or may not have a problem with seeing the wrong RPMs vs. VSS readings. Also, the shifts may try to happen too early, as they would be mapped for 4.44. Differences in clutch pack specs for 4cy vs. 6cyl may also cause shifts to feel clunky or laggy.....not sure but since the differences in the trans are there, it's possible. Not sure if the wiring would allow swapping TCUs to match. It might. But then also the H6 TCU may want a different type of TPS signal.....again not sure. Basically, yes it will drive if you swap diffs. The nuances about how well it will actually perform and if you'll be happy are hard to parse. I would find a good 4 Cyl Outback or Forester trans.

sirtokesalot Posted September 18, 2019 Author Share Posted September 18, 2019 (edited) well today i did the swap the transmission is bolted in there now. i forgot thefluid here at home so did not fill it yet. will it cause damage to the 4.11 transmission if i were to run it with the 4.44 diff with the fwd fuse installed? id like to try to drive it before i swap the diff over as well just to find out if it all works before spending that extra effort. would like to figure it out before morning. im planning to go up there again tomarrow to finish it.

sirtokesalot Posted September 19, 2019 Author Share Posted September 19, 2019 (edited) well im getting ready to head back to the car to finish up. i guess ill just swap the diff and hope this transmission works out. wish i knew if i could drive it with the wrong diff and fwd fuse first to find out if it will work before doing the effort of changing the diff. but id rather not cause damage and i just dont know if it will with the fwd fuse in or not.

FerGloyale Posted September 19, 2019 Share Posted September 19, 2019 It SHOULD be okay to test drive a little with FWD fuse in. Alternately, you could remove the rear section of center section of the driveline. 1 Quote Link to comment Share on other sites More sharing options...
CNY_Dave Posted September 19, 2019 Share Posted September 19, 2019 I would say safe for testing, but maybe not for regular use. The plates will be spinning relative to each other at a fast rate and any tiny bit of friction will cook 'em. Quote Link to comment Share on other sites More sharing options...
sirtokesalot Posted September 19, 2019 Author Share Posted September 19, 2019 heres the results. i did change the diff the transmission does work and does not set any codes seems to drive ok with light throttle/normal driving but under heavy throttle/acceleration scenarios it has some really funky shifts. engine can pull the gears ok doesn't seem to be slipping or struggling too hard. seems like i can drive it though until i find another good transmission. in the end this did not cost anything but time the h6 transmission and diff was free Quote Link to comment Share on other sites More sharing options...
logic23 Posted September 20, 2019 Share Posted September 20, 2019 It will be less trouble to get the right trans. You can get low mileage ones from the JDM outfits for 2-300. Or any junkyard they dont fail that often so you have good ods that youll get a good one . Quote Link to comment Share on other sites More sharing options...
sirtokesalot Posted September 21, 2019 Author Share Posted September 21, 2019 (edited) does anyone know if the transmission from a 2005 forester would work in my 2001 outback? i found a transmission for 100 bucks from a rollover with 71,000 on it. i dont really get that website.

I think they would be too different. certainly the transfer valve and solenoid would have to be swapped, but worse I think the '05 forester had a much more electronic 4EAT.

sirtokesalot Posted September 28, 2019 Author Share Posted September 28, 2019 im going to assume i cannot use the transmission from a 1998 impreza can i? i have one of those on hand in another car i got free. Quote Link to comment Share on other sites More sharing options...
3Pin Posted September 28, 2019 Share Posted September 28, 2019 A used trans is usually not that expensive. IMHO, I would sell the free trans you have and buy the right one for your car. Just saying. that is what I might do. Quote Link to comment Share on other sites More sharing options...

Just saying. that is what I might do. ive been looking i jsut dont have cash for one currently. exploring my options. i was almost going to trade the 1998 impreza for a low mile trans but then realized it was a 2006 transmission and wouldent have worked. yes i would trade a running car for a transmission exp when said car was a free car. i do know i could get more by selling it and buying a transmission but it needs more work before i would sell it.

sirtokesalot Posted October 5, 2019 Author Share Posted October 5, 2019 is there any reason to fear a transmission that was stored outside with the axle stubs in and tail sealed? i found a 100 dollar 123,000 mile 4.11 legacy transmission.

Bugs and animals leave debris and weather exposure. Probably fine but there’s definitely room for stuff to happen. How long has it sat and where? 10 years on a weedy, shaded, over grown, cluttered side of a building is different from a clean, dry area with less debris, vegetation, etc. Quote Link to comment Share on other sites More sharing options...
