Dodge RAM 2500 3500 Remanufactured Manual Transmission 11792T

Description

Short-throw shift fork travel paired with multi-cone synchronizer engagement calibration locks in rapid gear selection across high-speed interstate logistics corridors under 650 lb-ft of continuous Cummins diesel torque. The Dodge RAM Remanufactured Manual Transmission outfits four-wheel-drive commercial trucks with an ultra-low 0.74:1 overdrive six-speed gear set. Each remanufactured unit undergoes precision case bore reconditioning, countershaft shimming, and dynamometer spin trials to verify fleet readiness.

Engineered from high-density die-cast aluminum in a two-piece split housing design, this transmission withstands severe shock loads while reducing vehicle tare weight. Carbon-metallic synchronizer friction cones replace older brass friction rings to prevent gear clash during fast cadence gear changes. Remanufactured shift towers include case-hardened selector forks and reinforced detent springs. Dual SAE six-bolt PTO ports accommodate auxiliary hydraulic equipment, while dry unit weight measures 225 lbs with a six-quart ATF+4 fluid capacity.

Key Features of Dodge RAM G56

Interstate transport operators buy Dodge RAM G56 remanufactured transmission units to optimize fuel economy and road speed under heavy fifth-wheel trailer loads. Every remanufactured transmission restores exact gear clearances while eliminating common aluminum case flex under peak Cummins diesel torque.

• 5.94 first gear ratio delivers exceptional startup torque multiplication on steep construction job site grades
• 1.375 inch ten-spline input shaft resists torsional shearing force under severe diesel torque spikes
• 29 spline output shaft connects flush with New Venture 271 and 273 transfer cases
• Multi-cone carbon synchronizers eliminate gear grinding across all forward gear changes
• Tall 0.74 overdrive sixth gear reduces highway engine cruising RPM to improve fuel economy
• Two-piece ribbed aluminum casing combines structural rigidity with substantial weight savings
• Dual six-bolt power takeoff apertures drive auxiliary dump bed and hydraulic crane pumps
• High-capacity tapered roller bearings maintain countershaft alignment under continuous heavy towing loads

Overdrive Ratio Torque Capacity

Engineered to manage 650 lb-ft of continuous input torque, this Severe Commercial Fleet specification handles severe commercial freight hauling without gear face micro-pitting. The six-speed gear set encompasses a 5.94:1 first gear, 3.28:1 second gear, 1.98:1 third gear, 1.31:1 fourth gear, 1.00:1 fifth gear, and an ultra-low overdrive 0.74:1 sixth gear. Sump temperatures maintain between 160°F and 195°F during severe operations. The ribbed aluminum case radiates heat straight into passing air currents, dissipating 52 BTU per minute during sustained highway towing.

Four Wheel Drive Interface

The 29-spline output shaft interfaces flush with New Venture 271 and 273 four-wheel-drive transfer cases with zero spline binding. Dial indicator measurements confirm mainshaft radial runout stays under 0.002 inches across complete revolutions. Precision bearing shims lock countershaft endplay to exact tolerances, preventing case deflection, fluid seal degradation, and transfer case input bearing damage under heavy torque.

Maintenance Protocols Fleet Service

Fleet maintenance managers must note this commercial manual transmission is not engineered for high-RPM sled pulling, abusive drag racing launches, or combined gross vehicle weights beyond 26,000 lbs. Adhering to structured lubricant service preservation protocols prevents casing heat distortion and preserves synchronizer friction lining cohesion under severe commercial duty.

• Check synthetic ATF+4 fluid level at the casing side inspection port each shift to verify adequate volume
• Drain and replace manual transmission fluid every 30,000 miles to eliminate suspended metal wear particles
• Inspect external shift tower rubber boots and transfer case mounting flange bolts every 12 months for looseness

Commercial Warranty Crate Manifest

Backed by a 3-Year / 100,000-Mile commercial fleet warranty, this manual drivetrain package ships freight secured inside a heavy polymer transit crate. Package contents include the remanufactured six-speed transmission unit, complete shifter tower module, replacement PTO port gaskets, detailed installation documentation, and dynamometer spin test verification paperwork.
