Not sure but think you may be looking at a hiesler 9 speed shift shaft thats missing the shift lever. Heisler also made a hydraulic pump drive disconnect. If the pictures work, first is a hiesler. Next is a model of M&W that also had a left side shift. Last is a M&W right side lever shift lever without the M&W shift rod to the lever. Look past the hydraulic valve to the lever in front of the brake pedals. M&W also used a push pull cable shift like used for pto operation on some trucks.
