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!

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

Some of these electrical diagrams may help as well.

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.
