This is a New Process 4-speed synchro transmission for a M-37 and similar Dodge military vehicles of post WWII vintage, but also will fit earlier WWII era Dodge military with 'crash box' 4 speed transmissions (change center floor board). This was completely rebuilt by owner and used in a '43 Dodge but removed because original crash box floorboard cowling didn't fit it. All synchros, bearings, plugs, balls and seals replaced. It has PTO flanges on both sides. Includes shift stick and a large box full of used and new parts. Main body casting # is C88671 & top plate is dated 9/25/53.This can be seen or picked up by appointment in SW Portland near Hillsdale and Multnomah Village.
