1998 Forester 'S', 167K miles.
Question: How can I diagnose if the clutch's Pressure Plate is bad vs. the transmission itself?
Starting about 2 weeks ago, car won't shift into 1st or Reverse easily. Usually have to turn off car. Sometimes going into 2nd then into 1st, or into 4th then into Reverse works. Car shifts OK into 2-5 gears.
On advice we replaced the Slave and Master cylinders as there was a TSB on the Slave cylinder. Didn't help.
Edit: Put in Subaru Extra-S fluid <3K miles ago.
We pulled the engine (w/2 people it went quickly), and I noticed the Tranquil sleeve kit TO bearing looked bad so we replaced it along w/the pilot bearing, which looked fine.
Here's what a new Tranquil bearing should look like (on the left):
After reinstallation (smoothest install ever!) it was a bit better for a few shifts but quickly returned to the same condition.
-Took it to the shop and they re-bled the master/slave cylinders which didn't help. They stated it appears the clutch fork is moving properly, just not fully disengaging the clutch. So they're leaning towards the PP vs. the transmission.
-July '10, during a turbo project, a freshly (properly) turned FW and new clutch/PP/TO(tranquil)/pilot bearing all installed. Shifted and drove fine for about 2K miles, 'til I gave up on turbo project (due to tuning issues).
-In March '11 original engine w/new HG's installed. All the same clutch pieces reused - but I had a hell of a time getting the engine installed. Once installed seemed to shift/drive fine 'til 2 weeks ago. But due to the PITA install I'm thinking I messed up something......
Thanks for your time!
