hey all, i'm having problems with my 92 legacy 4wd turbo sedan. it's been sitting now for over a year just about and i'm at my wits end. the problem just started one fine day after a nice long spirited drive. the thing is the tranny just seemed to loose "power"(for lack of a better word) while i was making my way home and i found that after parking i had lost reverse. there were no noises to indicate any problems(i.e. loud clunks or thuds) and also it's not quite like the tranny is slipping either just a loss in "power". i haven't tried anything since the end of last summer due to a lack of an indoor environment in which to work on it so now that it's getting nice out again i want desperately to try and get to the bottom of this. the fluid level seems fine and with "only" 120,000 miles on the car i'm wondering if the tranny filter could be the culprit? oh and by the way anyone know about how much a filter will set me back? well any ideas would be appreciated.

ok just read a couple other posts about filter lines being clogged and such and causing problems with the trannys. is this a viable cause for loosing reverse? and when i say loosing reverse i mean that it just sits and sounds like it's in neutral when i put it in reverse. doesn't sound like it's slipping more like it didn't engage.?.? perhaps a solenoid? or maybe a clogged line? would a tranny flush do more harm than good? i've heard some cases of people having their tranny's flushed in older cars and it actually blowing seals out and causing more harm than anything...

Sounds to me like you have lost hydrolic pressure. Have you checked both ATF and Gear Oil levels? Tried replacing external filter? Have you found any drips or puddles of ATF under your vehicle? Could be any number of things but hopefully it's not the hydrolic pump :( Start simple.

I normally dont post here but I saw you were the newest member to the USMB and wanted to check out your first post. Welcome aboard and hope we can figure this out for you! :)

nope no drips, levels check out fine, and no i haven't changed the filter yet and i'm hoping that's what it might be. thanks for the reply, although i used to be registered on the old board ya know;) it's just been a while i guess so i had to re-register:eek:

oh and by-the-by, any ideas on a price for said filter? and where one might acquire one? thanks again...

you can by the external filter in the retro-fit kit from subaru for like 10-20 bucks......if you want just the filter....it's an arm and leg....go figure.

I think the part number is in the sticky in the stuff you need to know forum on the www.bbs.legacycentral.org

The best maintenance for an automatic transmission is fresh fluid. If a flush blows out seals then they waited too long to perform maintenance. I hope a filter does the trick, but I think it might be a good time to consider the 5mt swap.

That filter is probably a dealer only part. It's not cost effective for other parts places to stock them.

Were you able to detrmine that your problem was related to not having the external filter kit? I have the same problem with my '90 and hope to identify the cause.

An update on this thread would be great. I have a 90 legacy that is shifting funny and I am wondering what I should do. How hard is the 5mt conversion?
