Technical Bulletin #1667

4AT Version 2 Phase 2Valve Body Layout, Solenoid Function w/ 2 Red ConnectorsThis bulletin applies to the following vehicles: 2004 and Later Forester Turbo, 2005 and Later Forester Non-Turbo, 2005 and Later Legacy/Outback, 2006 and Later Impreza Turbo and 2005 and Later Impreza Non-Turbo.

Subaru has a few different valve body configurations. The 4AT Version 2 Phase 2 has six solenoids in group and one linear pressure control solenoid that are separate. Many people refer to them as a “six pack” style.

The first step is to ID the valve body by the solenoid main connector. There are three different styles of connectors: single black, 2 blue and 2 red. Special thanks to Perfection Plus Transmission Parts.
