Subaru 4EAT Modifications

by | Jan, 1998 | Subaru, Subaru EndWrench Features | 0 comments

On all Legacy, SVX, and Impreza models equipped with 4EAT transmissions, when installing the new style high clutch hub, P/N 31550AA020, into an older style front sun gear with the bushing installed, the hub will not pass through the sun gear. It will be necessary to remove the hushing from the sun gear. This is a simple procedure and can be accomplished using a small punch.

Also, when installing thrust bearing P/N 806537010, it is necessary to install two (2). One bearing is installed between the high clutch hub and the front sun gear, the other between the high clutch hub and high clutch drum. These bearings must be installed correctly. The smaller inner bearing race must face the front of the transmission.
