Four-Cylinder Drivetrain Precision: Jeep Wrangler YJ AX5 Transmission Solutions.
The Aisin AX5 five-speed manual transmission was the factory gearbox paired with the reliable 2.5L four-cylinder engine in the Jeep Wrangler YJ from 1987 to 1995. Because it is engineered for lighter duty, the AX5 is highly sensitive to the added stress of oversized off-road tires and extreme trail modulation. Difficult gear engagement, popping out of gear during axle articulation, or loud bearing whine are classic indicators that your internal synchronizers and shafts require mechanical attention. Our specialized online inventory features professional-grade hardware to successfully overhaul and reinforce your classic manual gearbox.
