Early Six-Cylinder Drivetrain Precision: Jeep Wrangler YJ BA10/5 Transmission Solutions.

The Peugeot BA10/5 five-speed manual transmission was the factory gearbox paired with the 4.2L AMC inline-six engine in early Jeep Wrangler YJ models from 1987 to mid-1989. Featuring a highly distinct, vertically split aluminum case layout, the BA10/5 has unique maintenance and rebuilding requirements. Because it operates close to its mechanical limits when subjected to technical trail loads and oversized off-road tires, gear grinding, bearing whine, or fluid leaks at the input and output shafts are common maintenance milestones. Our specialized online inventory features professional-grade replacement hardware to successfully overhaul and seal your vintage manual transmission.


Trusted Quality for Your Vintage Gearbox: Crown, Platinum Driveline, and Omix.

For full-scale mechanical restorations, we stock highly detailed master rebuild kits from Crown Automotive, featuring all necessary main bearings, input and output seals, and comprehensive gasket configurations. Resolve difficult shifting or popping out of gear effectively with replacement synchronizer hubs spanning 1st to 5th gears. Rebuild your transmission's core mechanics with rugged input shafts, precision-cut gears for all speeds, and heavy-duty countershafts from Omix.
Ensure flawless engine engagement and superior torque transfer under heavy winch loads with premium clutch kits and flywheels with ring gears from Platinum Driveline. Keep trail silt and water out of your internal shifting mechanics with our precise input yoke seals, countershaft bearings, and durable rubber shifter boots. Our comprehensive range is finalized by accurate reverse light switches from Standard Ignition to keep your backup lights functioning reliably in any environment.


Expert Support for Your YJ BA10/5 Build.

Since the Peugeot BA10/5 featured a very short production run before being replaced by the AX15, accurate part identification for these early model years is paramount. Our outstanding customer service is here to guide you through choosing the correct shafts, bearings, and gasket layouts tailored to your specific build. With our fast shipping, your transmission components will arrive quickly, keeping your classic Jeep Wrangler YJ shifting smoothly through every terrain.
