The Mack 20QE3334A-3765 shift knob and airline kit is designed to service all Mack transmissions equipped with 2 or 3 airline shift knobs, including the T2090 and T2100. The kit replaces the three 3/16-inch airlines running between the slave valve and the shift knob, along with all fittings at the slave valve. Two 90-degree push-in swivel elbows allow installation without removing the slave valve from the top of the transmission, which eliminates the over-tightening risk that leads to synchronizer damage. The shift knob features a blue thumb button. Call us to confirm proper fit for your specific transmission.
