I recently bought a 1995 subaru legacy with about 180k miles on it. I knew when I bought it that it had an issue with the oil pressure guage, which I fixed. After that, it ran well for a few weeks. Then a few days ago I took it less than a mile to the store, and it drove great on the way there. When I tried to leave, the car died while backing out. It would start again, but die seconds later. I went and reset the wiring to the spark plugs and got it to run enough to get home. Now, if I start it and let it idle the at temp light flashes 16 times then the car dies. It always starts again on the first crank, then dies again. If I push the gas pedal at idle, it takes a bit longer before it dies. It dies almost immediately when trying to back out of a spot. I know the very basics about cars, but I am well versed using tools and multimeter in other situations, I just need to be pointed at where to start trying to diagnose this issue. Any help is appreciated! Thanks in advance! -
I have a 1998 Subaru Legacy. Recently the AT TEMP light flashes - 16 times- on start up. I took it to a general mechanic and a transmission specialist, and there were no codes. Also when making sharp turns, especially in reverse it seems to be stuck in 4wd. I put a fuse in the FWD, but that hasn't disengaged the AWD. I have done some research and I am guessing that it is what folks call torque bind and that it is the duty c solenoid that needs to be replaced. But I was also hoping that someone might have some thoughts about why the fuse isn't allowing it to run in FWD only. -
Hello. Thanks in advance for reading. A bit of a long post, I'm trying to provide as many details as possible. History I recently swapped a '95 4EAT (90k) and rear differential into my '92 Legacy L AWD Sedan. The original final drive ratio was 3.90, and is now 4.11. However, the winter tires I am using are significantly larger than the factory tires (I do not have tire clearance issues, BTW). The factory calls for 185/70 14s with a circumference of 76.017 inches, and I'm running 195/75 14s with a circumference of 80.161 inches. At the advice of the local Subaru guru, I did NOT swap the TCU. The steeper gears combined with the taller tires is a near-perfect match IF there were to be a TCU issue: 3.90/4.11 = 0.949 76.017/80.161 = 0.948 I've also verified this by calculating my speed through several mile markers. Symptoms 1) Intermittent, totally random failsafe mode (stuck in 3rd gear). This can happen at any speed, at any time, and for any duration. It can be downshifting normally as I slow to a stop, only to go into failsafe as I accelerate. I can drive it for 30 minutes on the highway with no problems when it suddenly drops to 3rd and revs. It can happen first thing in the morning when cold, or not. It can be in failsafe for two seconds or fifteen minutes. Totally random. Overall, it seems to fault approximately 25% of the time, and is not getting better or worse. 2) When it exits of failsafe mode, I receive one and only one power light indicator flash. I receive no indications when the 4EAT enters failsafe mode, and I am even sometimes unaware the the transmission has faulted until I observe the one flash. Occasionally, I also get one extremely fast AT temp indicator flash. This happens very quickly. So quickly, in fact, that I can barely even tell which indicator came on. The AT temp indicator may be flashing every time the power indicator flashes, but I don't think this is the case. I cannot tell because when I am able to visualize the indicator, it stays lit for just a split second. 3) Occasionally, but much more infrequently then the symptoms above, I receive the 16 power indicator flashes, indicating a stored TCU code. When I am able to retrieve the codes, I always receive a 32 and a 33 for vehicle speed sensors 1 and 2. 4) As to 3) above, I cannot always retrieve codes. When I follow Josh's code retrieval steps, the power indicator lamp does not always come on in step 3. Actions I've changed the fluid twice. It is always bright red with no burnt odor. I've used 1/2 bottle of red LubeGuard each time. I always keep the fluid right on the full mark. Next I do not think that I have a mechanical issue with the transmission. The intermittent but binary nature of the symptoms, combined with occasional lack of power indicator at startup point me to an electrical issue. I could try a '95 TCU, speed sensors, cleaning the transmission connectors, or cleaning and adjusting the throttle position sensor. Any other ideas? Thanks for the forum, the great write-ups, and the good community attitude. This is my first Subaru and I've had fun learning not only about my car, but what everyone else is doing. Dana -
I recently purchased my second Subaru, and it has some puzzling problems. When I start it up, it revs up to 1,500 - 2,000 rpm for 30 seconds and then drops down to 1,200. The AT Temp light flashes 16 times, and the Check Engine light is on. When I shift the transmission into gear and try to drive, it acts like the engine is under a very heavy load. At first, I thought the exhaust was clogged, but after checking, I don't think it is. As the car accelerates, it shifts very hard, and when I take my foot off the gas, the car slows down as if it had a stuck brake cylinder (but it doesn't). Finally, when I stop and shift to neutral or park, the engine still acts like it is under load. When I shut the engine off, the drivetrain relaxes, and the car rolls backwards a little bit. When I pull the code from the ECU, it tells me there is a problem with the idle air control valve. I took it off and cleaned it. I also tested the resistance on the pins, and they are around 9 ohms like they should be. Could my idle air control valve still be bad? What about this transmission problem? At first, I thought it might be the Duty C solenoid or transfer clutch, but I cannot read an error code from the transmission. I am using an ELM327 code reader. -
Hello USMB users, I am asking for help diagnosing a flashing AT Temp warning light on my 1998 Legacy L 2.2. The warning light flashes only when the car is started and the turns off after a few flashes. Also when making a tight turn it seems the wheels in the front are having trouble. They tires squeal even at speeds less than 5 mph and they seem to be "binding" or have trouble rotating when the steering is fully to one side. It seems like one wheel is slipping forward to keep up with the other. Thank you in advance. Dave
