Manual transmission won't shift into any gear except when engine off. What's up? on 2001 Subaru Outback

4th gear only worked downshifting not upshifting past four weeks. 1st-3rd, 5th and R O.K. but some grinding in shifting. Seems clutch is probably gone but I'm concerned transmission is gone too.
198,617 miles. Repair or trash???

replace the clutch. by driving it the way it is, you may have damaged the trans but only a shop can verify that.

Take it to a shop and get a compression test, I think you will find that there still lots of life in the car. And take it easy on the new clutch: They do wear out if they are slipped a lot or driven harder than a family car. Who new.
