Ford F-250 F-350 Remanufactured Manual Transmission 11885T

Description

Propel loaded 7.3-liter diesel fleet cutaway chassis up steep highway mountain grades under 420 lb-ft continuous mechanical shaft force without forward gear step hesitation through the Ford F-250 11885T Remanufactured Manual Transmission. This four-wheel-drive unit restores dependable pulling power to commercial diesel truck platforms.

Constructed in a heavy-duty cast aluminum casing, this five-speed manual transmission features molybdenum-coated synchronizer blocker rings and high-strength nickel-chromium gear sets. Tapered roller countershaft bearings handle severe forward thrust without case spreading. Precision-ground shift rails eliminate mechanical bind during cold-start shifting. Standard six-bolt PTO side plates permit hydraulic equipment operation. The bare transmission weighs 177 lbs dry and requires 3.4 quarts of synthetic manual transmission lubricant.

Key Features of Ford 11885T

Maintenance managers who buy Ford 11885T remanufactured transmission units gain verified driveline performance for heavy commercial hauling fleets. Comprehensive dynamometer testing confirms precise gear mesh patterns and flawless synchronizer operation across all operating temperatures.

• 420 lb-ft torque capacity easily withstands heavy diesel torque without component distortion
• 5 forward gear selections provide extreme reduction and efficient highway transit
• 0.76 to 1 overdrive gear ratio reduces engine wear during extended highway hauls
• 5.72 to 1 crawler first gear enables confident vehicle launches on steep dirt inclines
• Cast bronze shift forks with hardened contact points resist mechanical wear
• Pre-set bearing preloads eliminate mainshaft end-shake under severe load reversals
• Stiffened casing architecture dampens powertrain vibrations and gear noise
• Dual PTO side apertures provide mechanical power for external hydraulic tools

Mechanical Torque Step Evaluation

Designed for Severe Commercial Fleet operations, this manual transmission handles 420 lb-ft continuous input torque. Mechanical forward ratios span 5.72 to 1 in first, 2.94 to 1 in second, 1.61 to 1 in third, 1.00 to 1 direct fourth, and 0.76 to 1 in fifth overdrive. Reverse measures 5.24 to 1. Aluminum heat radiation releases 450 BTU per minute during sustained heavy towing.

Transfer Case Flange Union

The four-wheel-drive rear casing features a round six-bolt flange designed for flush connection with commercial transfer cases. A precision-machined 31-spline output shaft keeps total indicator runout under 0.002 inches to ensure silent operation. Heavy-duty internal detent springs keep the selected gear engaged through severe chassis twisting off-road.

Commercial Fleet Service Procedure

Examine clutch master cylinder rod clearance and inspect transmission mount bolts during standard fleet service intervals. This gearbox is not engineered for competitive drag strip racing or gross combined vehicle weights exceeding chassis factory specifications.

• Inspect oil level through the side fill plug every 250 hours
• Drain and replace manual gear oil every 30,000 miles
• Inspect external shift linkages for play each shift

Factory Crate Shipment Manifest

Backed by a standard 3-Year / 100,000-Mile commercial fleet warranty, this remanufactured gearbox arrives banded on a reinforced wooden pallet. Package includes the complete manual transmission, shift cover replacement gasket, reverse switch terminal, and dyno quality verification record.
