Scarpachy Posted April 9, 2008 Share Posted April 9, 2008 Who has the knowledge.? I have an 01 OB wgn with an AT temp light that comes on and flashes continually after driveing for awhile. I had it scanned and there are no codes present. It flashes with no apparent rythym. Once you shut the car off and sit for awhile it is off after the restart. The fluid is level, not burned and doesn't seem hot. Plus this is average driving with no excessive load. I did just change the burned fluid out and the light was on after. But it was on when i would first start it up after being cold. I put FWD fuse in for a bit and got it to shut off. But still comes on after driving for awhile. Any ideas would be greatly appreciated.

nipper Posted April 9, 2008 Share Posted April 9, 2008 You are begining to have an issue. Take it to a dealer ASAP, as it can mean the difference between a cheap repair and a 1000.00 or more repair. The TCU does not work off the OBDII scanner. You have pull the codes out to make the light flash out in morse code what the issue is. Someone will tell you how. If your bored do a search on it, it may atke a while to find. ANY FLASHING LIGHT is not to be ignored. It may be as simple as a bad tranny temp sensor, or something like a bad solenoid. AMy be as simple as a loose connection. Do you have any grabbing in tight turns? Usually the light will flash up on startup to tell you the last time the car was used something electrically went wrong. This is how my Duty C failure started, and it cost me 900.00 to fix. i too thought nothing of the light at first. I think you may have a failed or failing Duty C solenoid, and it just hasnt made itself known yet. This controls the AWD. Put the fuse in and let a dealer (NOT A TRANNY SHOP) take a look at it. good luck. nipper Link to comment Share on other sites More sharing options...
bheinen74 Posted April 9, 2008 Share Posted April 9, 2008 you said, "that you just changed the burned fluid out" above.... My friend, if you had burned fluid in there, you need to think about getting a new tranny. Link to comment Share on other sites More sharing options...

Sticking AWD clutches (no matter the source) will make burned fluid. Old fluid may have a burned smell to it. nipper Link to comment Share on other sites More sharing options...
Scarpachy Posted April 10, 2008 Author Share Posted April 10, 2008 no. Sticking AWD clutches (no matter the source) will make burned fluid. Old fluid may have a burned smell to it. nipper Yeah burned fluid does not mean the tranny is bad. It could have just been over worked or old. And it wasn't burned , just old and brown. Any way I thought clutches as well. But i have driven lots of subbys with bad clutch packs. And this one seems to be working fine. No binding. that i can tell. It did throw me off however that the fuse got the light to shut off the first time. Do you know if this year model, still locks the plates in to 50-50 split when in first gear. And also on side note. Supposedly the tranny shop has the proper scanner for pulling codes off the tcu. I have and obdII scanner, and know that you cant scan trans with it.

nipper Posted April 10, 2008 Share Posted April 10, 2008 90/10varied through to 50/50. It never locks the plates. It pulses them so that the torque bind is constantly released. Ther duration of the pulse is controled by the computer, and the pressure by an internal spool valve. There are also 5 other solenoids in the transmission Don't go to a tranny shop, for the love of all things holy. They will have your tranny apart for diagnoses before you know what hit you (like a 2500 plus repair bill). Go to subaru of at all possible. They dont want to sell you a tranny, just fix the problem. Subaru tranny is the only time i will tell someone to go to a dealer. nipper Link to comment Share on other sites More sharing options...

Gloyale Posted April 14, 2008 Share Posted April 14, 2008 Who has the knowledge.? I have an 01 OB wgn with an AT temp light that comes on and flashes continually after driveing for awhile. I had it scanned and there are no codes present. It flashes with no apparent rythym. If the AT temp light flashes at start up you have a code. Since you say it is after driving, and you have no codes (did they actually scan the trans codes or just ECU?) it may be a case where the Temp sensor is falsly reading high temp. This happens if the wire for the temp sensor shorts to ground, or the sensor shorts internally. I had a similar thing happen and it turned out to be the temp sensor wire was shorting out to the shielding around it. Link to comment Share on other sites More sharing options...
shortlid Posted August 27, 2010 Share Posted August 27, 2010 My Mom's '03 GT sedan just did this. Cold out of the garage A/T temp flashed for a Three mile trip to the Mall.

johnceggleston Posted August 27, 2010 Share Posted August 27, 2010 My Mom's '03 GT sedan just did this. Cold out of the garage A/T temp flashed for a Three mile trip to the Mall. Restarted after got there light came on for test and went right out??? A fluke, or worse??? in the 95 - 99 cars, this means there is an electrical problem in the trans, i assume the same is true for 00 - 04. there is a way to read the code and figure out whth the problem is. search for "trans* trouble codes" or something similar., maybe ''reading trans* codes" . how does the car run? is the trans fluid level ok?

shortlid Posted August 27, 2010 Share Posted August 27, 2010 (edited) Transmmison is running great no binding shifting where it always has. However, she did say that this happened after a long crank, where the car would not start. Then she tried it again and it started??

OB99W Posted August 28, 2010 Share Posted August 28, 2010 the TPS, throttle position sensor can and will throw a trans code. [...] In addition, with a turbo, MAF trouble can set a trans code -- with non-turbo, the MAP can. Link to comment Share on other sites More sharing options...
