S5-47 Manual Trans for 1996-1997 F-series 7.5L 2WD, 5 Speed, PTO Not In Use

Description

Second gear synchronizer bite loss and excessive shift rail endplay compromise freight transport deadlines until precision-ground carbon-faced blocker rings restore positive manual shift engagement inside the ZF S5-47 Remanufactured Manual Transmission engineered for 1996 to 1997 Ford F-Series two-wheel drive work trucks powered by the 7.5-liter big block V8 without PTO accessories.

One-piece cast aluminum housing architecture incorporates the 385-series big block bell housing pattern to fit 7.5-liter gas power plants. Carbon-faced synchronizer rings on second and third gears eliminate shift grind under heavy cargo bed loading. A heavy cast cover seals the side PTO window to prevent oil loss. Bare dry weight registers 175 lbs. Sump capacity holds 3.4 quarts of synthetic Mercon ATF fluid circulating past magnetic inspection bungs.

Key Features of ZF S5-47

Commercial fleet managers choose to buy ZF S5-47 remanufactured transmission units to eliminate gear hop and bearing squeal in dedicated highway freight trucks. Every rebuilt core receives brand new synchronizer rings, bearings, and seals to provide trouble-free manual shifting.

• Sealed 6-bolt PTO block-off plate stops gear oil leaks on non-PTO fleet trucks.
• Carbon-composite synchronizers prevent gear grinding during heavy trailer hauling.
• Precision ground helical gears handle 470 lb-ft continuous input gas engine torque.
• Hardened shift rails and detent springs stop transmission jumping out of gear.
• High-grade tapered roller bearings maintain mainshaft endplay within factory tolerances.
• Integrated aluminum bell housing bolts flush to Ford big block engine blocks.
• Remanufactured ZF S5-47 gearsets undergo spin checks to guarantee silent gear mesh.
• Viton input and output shaft seals withstand continuous 250°F operating spikes.

Big Block Reduction Torque Ratings

The 5-speed manual gear set provides close ratios featuring 4.14:1 in first, 2.37:1 in second, 1.42:1 in third, 1.00:1 in fourth, and 0.77:1 in fifth gear overdrive. Continuous duty designation supports up to 470 lb-ft continuous input torque at 2,200 RPM. Large helical gear tooth profiles divide driveline load forces across wider tooth contact surfaces. External casing cooling fins dissipate operating heat to maintain lubricant sump temperatures below 180°F under maximum gross combined vehicle weights across demanding commercial haul routes.

Shaft Spline Alignment Clearance Specifications

A 10-spline 1.25-inch diameter input shaft seats into standard big block clutch discs with zero spline bind. The rear output shaft links straight to chassis driveshafts with dial indicator runout held below 0.002 inches. Heavy-duty rear extension housing bearings support driveshaft weight without deflection or premature seal failure.

Manual Gearbox Operational Service Standards

Check clutch hydraulic master and slave cylinder travel to ensure complete disengagement before initial road testing. Fill the transmission case using synthetic Mercon ATF fluid through the side inspection port. This unit is not engineered for closed-course drag strip racing, extreme rock crawling, or gross combined vehicle weights exceeding factory chassis tow limits.

• Inspect front quill tube and rear extension housing for fluid leaks each shift.
• Drain transmission fluid, clean magnetic plugs, and refill every 30,000 miles.
• Check manual transmission mount bushings and crossmember bolts every 12 months.
