OTC's Air-Assisted 2,000 pounds Capacity High-Lift Transmission Jack is designed for shops with in-ground or above-the-floor vehicle hoists. The low minimum height of 41-1/2 inches allows transmissions to be rolled out from under a bus or other vehicle's frame - avoiding a clearance problem faced by competitors' jacks. The metered, foot-operated air pump allows effortless lifting of the transmission into place, controlling the load precisely during removal and installation. The operation is twice as fast as competitive jacks powered by a hand pump, and it costs less. A dedicated adapter for the popular Allison 500 and 600 series automatic transmissions is included. Built in safety bypass prevents damage caused by a system overload. Covered by Lifetime Marathon Warranty. Value is at the core of the OTC tool and equipment portfolio.
