T56 Manual Trans for GM 1994-1997 Camaro & Firebird, 6 Speed, Internal Slave

Description

Propel loaded 5.7-liter fleet cutaway chassis up steep highway mountain grades under full mechanical gear lock force without forward gear step hesitation through the GM T56 Remanufactured Transmission built for 1994 to 1997 Camaro and Firebird internal slave applications.

Cast aluminum structural housings incorporate internal hydraulic release bearing support sleeves. Carburized 8620 steel gear clusters combine with double-cone synchronizer assemblies and heavy-duty shift rails to resist bending forces. A 3.8-quart fluid reservoir maintains constant splash lubrication to internal bearings. The front shaft utilizes a 26-spline design matching factory performance clutch assemblies.

Key Features of GM T56

Commercial performance fleets buy GM T56 remanufactured transmission units to ensure total vehicle reliability on demanding driver training tracks. Rebuilt internal synchronizers prevent gear shift lockout during high-rpm shifting.

• Integrated concentric slave guide sleeves ensure smooth hydraulic throwout bearing travel
• Double-cone carbon synchronizer rings resist thermal breakdown under aggressive downshifts
• Bronze shift fork pads provide positive rail engagement without cracking under hand force
• Nitrided gear teeth resist micro-pitting under sustained high-load vehicle acceleration
• GM T56 drivetrain units undergo spin testing to verify smooth shift rail movement
• Machined countershaft support plates prevent shaft spreading under high torque spikes
• Internal magnet traps metallic sediment to protect needle roller bearing surfaces

Mechanical Torque Capacity Gear Calculations

Engineered for high-stress vehicle fleets, this six-speed manual transmission channels 450 lb-ft continuous input torque at 4,000 RPM. Sump temperature operates between 165°F and 190°F across severe duty cycles. Gear reduction steps feature 2.66:1 first, 1.78:1 second, 1.30:1 third, 1.00:1 fourth, 0.74:1 fifth, and 0.50:1 sixth overdrive, dissipating 55 BTU per minute across the case exterior.

Rear Driveline Yoke Spline Alignment

Power outputs through a 27-spline shaft designed to mate with GM 1.375-inch slip yokes. Total dial indicator runout along the output shaft holds under 0.002 inches across 360-degree rotation. The rear aluminum housing incorporates an oil drain trough to keep the rear bushing lubricated.

Manual Clutch Throwout Maintenance Schedule

Flush hydraulic clutch fluid periodically to prevent concentric slave cylinder seal contamination. This manual transmission is not engineered for heavy trailer hauling, truck conversions exceeding axle ratings, or extreme mud bogging use.

• Inspect hydraulic clutch line fittings each shift
• Drain and change manual transmission fluid every 30,000 miles
• Inspect transmission rubber mount bushings every 12 months

Fleet Warranty Crate Shipment Inventory

Backed by a comprehensive 3-Year / 100,000-Mile commercial fleet warranty, this unit provides dependable long-term service. Shipment contains a fully remanufactured six-speed transmission, reverse inhibitor solenoid, internal slave shim kit, and a dyno test verification document.
