#202 of 580 LOW MPG! by slappro

Apr 15, 2008 (1:12 pm)

I recently bought the 1996 subaru legacy outback.
I had auto transmission work done on it to replace the timing mechanism that engages the clutch (it looks kind of like a wagon wheel... can't remember what it's called). The transmission light is still on, according to the mechanic, because of an electrical issue not effecting the performance of the transmission. I'm not sure I believe him. Also I at the same time had some brake work done because the ABS light was on.
 
The problem is that this car is getting 14 mpgs! I have no idea why. It should be getting 20 mpgs city and it is not even close.
 
I have run fuel system cleaner through with no results.
Help!

hi; the problem that you are getting with the grabbing, is comming from end of the transmission where it joins to the rear propeller shaft going to the rear wheels, depending on the year or model, if its an auto, you would have to change the rear extension housing, check first to see if it has a ball bearing that can be replaced,

hi; first you should clear the error codes from the ecu . go to" www.legacy central.org". then click on, "the library", then under the heading marked "tech doc", click on "ecu error code instruction and glossary", it should read, "how to read trouble codes from the ecu" print it out, study it you can do it yourself, subarus are nice, but you have to learn to tweek them yourself.

I have a 99 with manual and had similar issues. Replaced both front shafts. Finally figured out with subaru support that the center differential was bad.

I have an intermittent problem with a 1999 SUS w/82000 miles. After driving at 60 MPH on a highway for several miles it starts to feel that I'm driving on rough pavement. Vibration and noise increases. The intensity can vary to the point it feels like I'm driving on the highway rumble strips. Sometimes the problem just disappears. It seems related to the locking of the torque converter. As soon as I exit the highway or slow down sufficiently for the torque converter to unlock, the ride becomes smooth. I can drive at lower speeds (i.e. 40 MPH) and never experience the problem. Any thoughts or suggestions would be greatly appreciated.

its is very possible that the torque is your problem i would not hesitate to replace it otherwise if the torque fails so does the transmission

I had a very similar issue that was a tire/rim problem on a FWD vehicle. It was very difficult to diagnose even for the tire shop.

Try putting the FWD fuse in under the hood. That will have the car run in FWD mode and this may help you narrow down where the problem is (center diffy, front or rear diffy)

The behavior is the same whether forced into FWD (fuse in FWD fixture) or running in AWD.

Hello all,
  I am new to the forum and am looking at a 96 Outback with 142k on it. I plan on replacing the timing belt and head gasket (If it already hasn't been done). Anyone out there info on doing this? Maybe an online repair manual? I have replaced timing belts and head gaskets on my other vehicles but have never owned a subaru. Any other things to look for when test driving. Thanks in advance for all your help. Don
