Ford F-250 F-350 Remanufactured Manual Transmission 11880T

Description

Prevent gear slip and countershaft separation under 420 lb-ft sustained hauling output while maintaining 185°F casing thermal stability during demanding municipal utility maintenance operations using the Ford F-250 11880T Remanufactured Manual Transmission. This four-wheel-drive unit restores dependable gear control for demanding municipal fleets.

Manufactured inside a ribbed aluminum casting, this five-speed manual transmission integrates molybdenum synchronizer blocker rings and carburized steel gear teeth. Tapered roller countershaft bearings handle continuous thrust loads without axial drift. Steel shift rail detents secure selected gear positions through heavy chassis vibration. Left and right six-bolt PTO apertures permit direct hydraulic equipment drives. The dry unit weighs 176 lbs and holds 3.4 quarts of synthetic manual transmission lubricant.

Key Features of Ford 11880T

Fleet directors decide to buy Ford 11880T remanufactured transmission units to restore full powertrain reliability across municipal service trucks. Each remanufactured unit undergoes strict mechanical clearance verification to ensure long component life under extreme commercial duty cycles.

• 420 lb-ft torque rating supports continuous commercial towing without shaft twist
• 5 forward mechanical speeds yield full control across off-road and highway terrains
• 0.76 to 1 overdrive gear ratio saves fuel during interstate transport cycles
• 5.72 to 1 deep crawler first gear moves stalled equipment without clutch burn
• Wear-resistant bronze shift forks ensure crisp gear engagement under heavy use
• Pre-adjusted countershaft shims eliminate gear train end-play under severe reverse shock
• Rigid aluminum casing structure limits noise and vibration transmission to the cab
• Side-mounted PTO access plates drive auxiliary winches and hydraulic utility cranes

Torsional Ratings Gear Multipliers

Engineered for Severe Commercial Fleet service, this gearbox channels 420 lb-ft continuous input torque. Mechanical gear reduction ratios measure 5.72 to 1 first, 2.94 to 1 second, 1.61 to 1 third, 1.00 to 1 fourth direct drive, and 0.76 to 1 overdrive. Reverse gear provides 5.24 to 1. Structural aluminum cooling ribs dissipate 445 BTU per minute under sustained vocational towing.

Transfer Case Coupling Architecture

The rear casing bolts straight to four-wheel-drive transfer cases via a circular six-bolt mounting flange. The 31-spline output shaft maintains precise mechanical alignment with transfer case input gears, holding total runout under 0.002 inches. Spring-loaded internal detent balls maintain firm shift engagement over rough terrain without unwanted gear disengagement.

Field Service Maintenance Rules

Examine clutch slave cylinder travel and verify gearshift lever boot integrity during routine preventative maintenance cycles. This transmission is not engineered for competitive tractor pulling or vehicle payloads that exceed chassis manufacturer gross weight ratings.

• Check gear oil level at the threaded casing plug every 250 hours
• Drain and replace manual gear oil every 30,000 miles
• Inspect driveshaft universal joints for play each shift
