NV3550 Manual Trans for 2000-2001 Jeep Cherokee, 2WD, 5 Speed

Description

Cast aluminum two-piece casing architecture absorbs severe structural road shock while carbon-composite synchronizer rings handle 235 lb-ft during grueling vocational work truck operation in the Jeep Cherokee 2WD NV3550 Remanufactured Transmission configured for 2000 to 2001 Jeep Cherokee two-wheel drive utility models equipped with 4.0L inline-six gas engines.

A split-case cast aluminum housing design encloses case-hardened 8620 steel helical gear sets, carbon-composite synchronizers, and heavy tapered roller bearings. Independent intermediate shaft supports eliminate mainshaft flex under heavy acceleration. The gearbox weighs 97 lbs dry, holds 2.1 quarts of Synchromesh manual lubricant, and incorporates a rear slip yoke extension housing.

Key Features of Jeep Cherokee

Utility service supervisors choose to buy Jeep Cherokee manual transmission packages to eliminate first gear hop-out and restore driver shift control in dense traffic conditions. Remanufacturing addresses critical factory synchronizer hub tolerances.

• 5-speed manual gear architecture provides close ratio steps to maximize 4.0L engine power bands.
• Carbon-composite synchronizers eliminate shifting notchiness between first, second, and third speeds.
• Case-hardened steel shift forks prevent fork spreading under rapid commercial driver inputs.
• Shot-peened gear tooth roots provide high fatigue resistance under continuous stop-start driving.
• Jeep Cherokee NV3550 units feature precision ground output journals to eliminate slip yoke play.
• Heavy-duty input shaft quill tubes provide smooth clutch release bearing travel without stickiness.
• Internal casing magnets catch ferrous debris to keep synthetic manual transmission fluid clean.

Hydraulic Line Limits Dynamic Ratios

Engineered to handle 240 lb-ft continuous input torque at 3,200 RPM, this gearbox operates without countershaft deflection under demanding postal fleet routes. Aluminum casing surfaces dissipate operational heat, holding fluid sump temperatures below 180°F. Gear ratios provide 4.01:1 first gear, 2.33:1 second gear, 1.39:1 third gear, 1.00:1 fourth gear, and 0.78:1 fifth gear.

Slip Yoke Interface Concentric Alignment

The two-wheel drive rear tailhousing contains a 27-spline output shaft designed for sliding rear driveshaft slip yokes. Output shaft journal runout remains below 0.001 inches, halting tailhousing seal fluid leaks. Bell housing bolt patterns mate flush with AMC 4.0L inline-six engine blocks using precision dowel guide sleeves.

Shift Detent Protocol Maintenance Limits

Inspect external manual shift boot rubber seals and verify hydraulic clutch line bleeding before putting vehicles in service. This manual transmission is not engineered for competitive off-road rock crawling, forced induction engine modifications, or towing trailers exceeding 2,500 lbs.

• Inspect clutch hydraulic master and slave cylinders for fluid weepage every 10,000 miles.
• Drain and replace manual transmission fluid using approved Synchromesh lubricant every 30,000 miles.
• Verify transmission rear crossmember mount bushing condition every 12 months.

Warranty Statement Logistics Crate Contents
