Auto to manual trans coversion?

I have a 96 Ford F-350 Dually IDI powerstroke, automatic trans, and i'm wondering what transmission shops could do a auto to manual conversion In eugene oregon

Sure, but it would be expensive & time consuming. Easier to just trade it in on a manual…

Sure. Guesstimate will be several thousand dollars. Between labor, transmission, flywheel and clutch assembly, hydraulics, along with some other modifications

ANY GOOD TRANS CAN DO IT.

Your engine is not IDI nor was that engine part of the Powerstroke line. That engine was discontinued in 1994 when the Powerstroke 7.3 debuted midyear.
