I'm using a wright 2.0 open-ended 17 mm wrench.

The transmission body will not allow the wrench to rotate any suggestions?

Are there wrenches with thinner openings so that I can rotate?

Any tricks anyone can share to get this off so that I can regain use of my speedometer and be out of limp mode.

1998 Subaru legacy wagon five speed I believe it's a 2.2L.
