    I have owned this car for several years and done much work on it...It is now experienced electonic difficulties which prevent it from driving.

    1997 Legacy L + 1997 Legacy L
  1. I have 2 (two) 1997 Legacy wagons. EJ22 5MT Normally aspirated. Both took the beating a career pizza delivery guy could dish and now one at ~270,000 miles; each has a HG leak. I will soon commence the HG replacement and clutch on one. I am looking for several pieces of advice, tips, tricks and whatever input persons with experience may have... HG thickness/brand -- I see MLS in varying thicknesses from 0.040" to 0.088" available from Cometic, Six Star and Mahle. Clutch kits -- plates, flywheels brands seem to be about the same from various suppliers with the throw bearing being a crucial subaru component. Engine Hoist/ mount-- Since I will be replacing the clutch as well obviously pulling the engine is essential and makes HG replacement easier. Can I get by with a rope pulley system from the garage rafters lowered onto brick/wood support (I don't really want to be working on the engine on the ground) or should I rent/purchase engine hoist and mount? Thanks in advance- John
  2. After replacing the TPS on my '97 2.2 A/T with one from the junkyard I declared my car repaired from it's transmission problems and P0720 (output speed sensor circuit) error code. It initially drove and shifted wonderfully (no CEL). However 50 miles down the road it was back to it's old ways going into "limp mode" 2nd gear selected. I unplugged and reattached the electrical connectors to the transmission and was in the process of back-probing the TPS when I accidentally touched the wrong probe--which showed I was getting continuity across the terminal with the ignition off. This seems to be wrong--what say you?
  3. I have attempted to locate the connector under the dash for the diagnostics described as "black" but cannot find it. Am I looking for a connector with nothing connected to it or will it be connected to more wires? I am using this diagram:
  4. Can't express my regret that my previous post was incorrect. The used TPS TEMPORARILY FIXED the problem!!! What is going on with this crazy car? It must be electronic in nature. I think I am just going to go through all the connectors and detach/re-attach them because this intermittent problem with the trans crept up again after about 50 miles of perfect driving/shifting. Although this time it was giving me an AT trouble code the first couple times I drove it.(?) Also I will look for this illustrations which show the AT trouble code connector cause I could not figure out which one it was.
  5. It is confirmed that the solution to my transmission problem was in fact the TPS, After installing one from a junkyard for $17.50 ($99.50 for a new one) the car has no shifting problems or dropping gears. Now to catch up on the rent because of lost economic opportunity.. Thanks Johnceggleston and USMB!!! I really don't think the solution would have occurred to me without your input!
  6. So I just checked the TPS according to the Haynes by backprobing the harness with ignition on. V-meter showed voltage but it was unchanged when the throttle was moved. It did make a humming noise ,of which I could not positively identify the source, as the throttle was moved. Is it common for a TPS to fail and cause this problem?
  7. Thanks for clarifying about the handshake method and OBD2-- I had been wondering. Typically, it the AT Temp light does not flash when the vehicle is started. But if it is not immediatly on the CEL will light up after a couple miles. The returned code is P0720.
  8. the code retrieved was P0720- "output speed sensor circuit." The AT Temp light only flashes after I attempt to retrieve AT codes through "secret handshake" method. (drive, depress brake,put car into first gear, turn off ignition, turn on ignition, put transmission into 2nd back down to 1st the up through drive. it does not give me codes or anything at that time; but after sitting when I return to the car it flashes rapidly...I have read that this is a power supply or grounding issue code.) By TPS you mean throttle position sensor?
  9. My legacy has recently began losing 3rd and 4th gears after driving beyond 20 miles or so. The ATF is good. I believe the problem is electronic and replaced the vehicle speed sensor (top passenger side of AT). The code I retrieve is for the output speed sensor circuit. (I am beginning to see my solution as I type) Has anyone else experienced this problem? I am hoping that it is a simple wire harness fix or sensor swap. Are all Gen 1 sensors interchangeable in the AT? (i.e. can I swap a sensor from a '99 AT to my '97?)
