2000impreza Posted March 12, 2009 Share Posted March 12, 2009 Can someone help identify these solenoid in my transmission. Inside the Trans oil pan. Need to find out which is the 2-4 brake duty, Pressure Solenoid, ATF sensor, AWD Solenoid and etc. Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted March 13, 2009 Share Posted March 13, 2009 i have 2 pdf files erom a esm which may help. send me a pm with email address and i'll send them along. pm sent. Quote Link to comment Share on other sites More sharing options...
2000impreza Posted March 13, 2009 Author Share Posted March 13, 2009 John, my email is beemae@yahoo.com. Do you by chance know what each solenoid resistance reading should be at??? Quote Link to comment Share on other sites More sharing options...
nipper Posted March 13, 2009 Share Posted March 13, 2009 Acn you handle a 14,000 KB email, I have a manual form a 2002 Imprezza if that would help. Quote Link to comment Share on other sites More sharing options...
nipper Posted March 13, 2009 Share Posted March 13, 2009 1- Lock Up Duty 2- Line Pressure 3- Low Clucth Timing 4- Shift Solenoid 2 5- Shift Solenoid 1 6- 2-4 Brake Timing Solenoid 7- 2-4 Brake Duty Solenoid Quote Link to comment Share on other sites More sharing options...
2000impreza Posted March 13, 2009 Author Share Posted March 13, 2009 (edited) Thanks nipper. So where is the AFT Temp Sensor located at ??? Edited March 13, 2009 by 2000impreza Quote Link to comment Share on other sites More sharing options...
nipper Posted March 13, 2009 Share Posted March 13, 2009 The thing on the end of the brown plug. Quote Link to comment Share on other sites More sharing options...
2000impreza Posted March 14, 2009 Author Share Posted March 14, 2009 Nipper, Also do you know what each of these solenoid resistance reading should be at?? Thanks, you guys been allot of help. Quote Link to comment Share on other sites More sharing options...
nipper Posted March 14, 2009 Share Posted March 14, 2009 For that i have to send you the manual, as they speak of voltages and it is sort of spread out all over the manual. Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted March 14, 2009 Share Posted March 14, 2009 (edited) have you double checked the trouble code for your trans. i'm not suire 76 is a valid code. Edited March 14, 2009 by johnceggleston Quote Link to comment Share on other sites More sharing options...
2000impreza Posted March 14, 2009 Author Share Posted March 14, 2009 I was able to find 76. It's the 2-4 brake duty solenoid. Got from alldata DTC codes Quote Link to comment Share on other sites More sharing options...
nipper Posted March 14, 2009 Share Posted March 14, 2009 have you double check the trouble code for your trans. i'm not suire 76 is a valid code. That was easy to find. 76 is the 2-4 brake timing solenoid. It is detecting either an opne or a short circuit. FOund it resistamce is 10-16 Ohms. Signal from the TCU should be higher then 9 volts. The proper way to test the output requires getting the car up to 40 mph. It seems like something straight forward to check as far as no surprises in the circuit. nipper Quote Link to comment Share on other sites More sharing options...
2000impreza Posted March 14, 2009 Author Share Posted March 14, 2009 Nipper, Which pin # on connector B54 should I use to measure the 9 volts. For that I have too drive the vehicle up to 40 mph to get the proper reading on the TCU connector on B54?? Quote Link to comment Share on other sites More sharing options...

2000impreza Posted March 14, 2009 Author Share Posted March 14, 2009 you can send to my email::: beemae@yahoo.com From the reading do you think that the (Line Pressure, and the 2-4 Brake Duty Solenoid) is broken. So would this be the reason why I am getting the "AT OIL TEMP" light flashing. There was no cut or broken lines to these Solenoid. I was able to do the resistance measuring::: 1.) Lock Up Duty- 12.5 2.) Line Pressure Duty Solenoid- O.L 3.) Low Clutch Timing- 12.8 4.) Shift Solenoid #2- 12.7 5.) Shift Solenoid #1- 12.7 6.) 2-4 Brake Duty Timing Solenoid- 12.8 7.) 2-4 Brake Duty Solenoid- 3.1 8.) AFT Temp Sensor- 12.6 Quote Link to comment Share on other sites More sharing options...
OB99W Posted March 15, 2009 Share Posted March 15, 2009 2.) Line Pressure Duty Solenoid- O.L Should be about 3 ohms. OL stands for 'OverLoad', and usually indicates an open circuit when the meter is on a resistance range. If that's what your meter reads when the leads aren't connected when measuring ohms, then that solenoid coil is apparently open. However, it would correspond to an AT code of 75, not 76. 7.) 2-4 Brake Duty Solenoid- 3.1 Assuming that's 3.1 ohms, it's a normal reading (has same resistance spec as for the Line Pressure Duty Solenoid). 8.) AFT Temp Sensor- 12.6 Since the ATF Temp Sensor changes resistance with temperature, the reading will naturally depend on temperature. However, 12.6 ohms seems way too low. Perhaps you measured something else, or you didn't include a resistance scale multiplier in what you reported. Can you recheck the temp sensor resistance? The rest of the readings are within tolerance. Quote Link to comment Share on other sites More sharing options...
2000impreza Posted March 15, 2009 Author Share Posted March 15, 2009 OB99w, How I did the resistance measurement for the Line Pressure Solenoid. Was I pull the clip off the Line Pressure Solenoid and Positive Terminal on the solenoid, and Grounded it on chasis Ground. Reading was O.L Did every single one the same way, and got 12.5-12.8, 2-4 Solenoid was 3.1ohms. "Except for the Line Pressure Solenoid". I think I should still get the same resistance as 2-4 solenoid but got O.L. As you stated it should be the same as 2-4 solenoid. Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted March 19, 2009 Share Posted March 19, 2009 any progress on this repair? Quote Link to comment Share on other sites More sharing options...
2000impreza Posted March 20, 2009 Author Share Posted March 20, 2009 Just order the LINE PRESSURE DUTY SOLENOID. Well see what happens after i replace the solenoid. Quote Link to comment Share on other sites More sharing options...
