HobbyWrench Posted January 16, 2005 Share Posted January 16, 2005 Would anyone have a .pdf file or link to a Subaru Service Manual that includes the Transmission and Differential Section for my '90 Legacy LS? (Unfortunately, $$$ are an issue for me right now.) It appears I have a Duty Solenoid "B" problem and want to see what it would take to diagnose it. Is there any long-term concern if I just ignore this 'warning'? The car has 170K miles, I've owned it for the last 5K and it appears to run fine. Thanks!

Legacy777 Posted January 17, 2005 Share Posted January 17, 2005 I don't have any of the transmission manual scanned, and I don't believe the guy I got the engine & engine electrical from does either. Is there anything in particular your looking for? If you're getting a duty B solenoid error code, I'd check the wiring going to the duty b solenoid and see what the resistance is. I can then compare that to what the manual says. These scans should help you determine which pins are the duty b solenoid http://www.main.experiencetherave.com:8080/subaru_manual_scans/FSM_Scans/TCU_I-O_page1.jpg http://www.main.experiencetherave.com:8080/subaru_manual_scans/FSM_Scans/TCU_I-O_page2.jpg Some of these electrical diagrams may help as well. http://www.surrealmirage.com/subaru/swap/electrical.html The duty b solenoid handles torque converter lockup. The car will work, and drive, you'll just get worse gas mileage and performance because the torque converter isn't locking up. Quote Link to comment Share on other sites More sharing options...
