92 Legacy AWD 4EAT will not shift into 3rd, does go 1st gear to 2nd gear okay, dropped the pan, magnet has about a tablespoon amount of iron filings and no big chunks of metal. Shift solenoid connector with blue wire ohm tested over specs at 47 ohms. TCU error codes are 32 and 33. What should I do next to fix this? What parts do I need and where do you recommend I get them? Thanks.
