MiataPaul Posted September 18, 2008 Share Posted September 18, 2008 Ok I have a 91 Legacy 5 speed and am looking at a 97/98 Outback 5 speed with a bad transmission. Will the transmission from the 91 work in the 97? I may be able to get it cheap. I did a search and could not dig anything up relevant.

subaru360 Posted September 18, 2008 Share Posted September 18, 2008 It will work, you will need to check and see if they use the same final drive ratio. If not, it's not a big deal, just swap the rear diff also. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted September 19, 2008 Share Posted September 19, 2008 in general yes, they'll swap easily. a few things to be aware of: make sure the rear diff ratio matches the transmission diff ratio (trans and front diff are one unit on these). they will not be the same - so you can just swap the rear diff too. is the outback a hydraulic clutch or cable? the Legacy GT sedans are always hydraulic clutches, so you'll have to work around that since the 91 will be a cable clutch. in either 98 or 99 the bellhousing bolt pattern changed, still doable but it's 4 vereses 8 bolt pattern - though the 4 still line up and "work". so you'll need to verify that and whether this is a 97 or 98 if it even matters.

subaru360 Posted September 19, 2008 Share Posted September 19, 2008 From the ones I've seen the outbacks went to hyd clutch with the change to the 8 bolt pattern in 99. But if you have both complete cars, you'd have everything you need to do the swap either way, just a little more work if you had to swap pedal assemblies.

My 1997 OB has hyd. clutch so it's ealier than 99. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted September 19, 2008 Share Posted September 19, 2008 You should be able to keep the hyd. clutch setup. To my knowledge the pivot ball is just moved to the other "boss" (you may have to tap it) and you can swap over the hyd clutch fork & slave cylinder.

If you end up not being able to use the 97 OB I need the front of the propeller shaft for my 97 OB.
