6HP26 2006-2008 BMW 760i, 760Li 6.0L RWD – Remanufactured 6-Speed Automatic Trans

Description

Featuring a 4.17:1 first gear reduction ratio and 295 PSI hydraulic line pressure thresholds, flagship V12 luxury sedans maintain continuous forward acceleration through demanding highway passenger routes under the BMW 760 6HP26 Automatic Transmission configured for 2006 to 2008 BMW 760i and 760Li 6.0-liter V12 sedans. This unit sustains smooth gear shifts and protects internal hard parts from high-torque strain.

The casing is cast from high-density aluminum alloy to maintain structural rigidity against V12 engine torque loads. Hard-anodized Sonnax sleeves restore worn mechatronic valve body bores to stop internal fluid leakage across shift circuits. Driveline hardware includes 3/8-inch inverted flare cooler ports, an 11.25-inch torque converter bolt circle, and an unladen dry weight of 190 lbs. The transmission fluid pan holds 10.5 quarts of high-specification synthetic automatic transmission fluid.

Key Features of BMW 760 6HP26

Fleet directors buy BMW 760 6HP26 automatic transmission packages to preserve drivetrain efficiency across demanding municipal and corporate executive vehicle routes. Every remanufactured unit undergoes computer-controlled dyno testing to verify mechatronic valve response under simulated road resistance.

• 270 PSI main line pressure calibration maintains firm clutch pack clamp force across all gears under V12 power.
• 6 forward computer-managed gear ratios provide rapid low-end acceleration and quiet high-speed highway cruising.
• 7 carbon-metallic friction plates per clutch pack eliminate clutch slippage under continuous high-torque driving.
• 0.0014-inch gear tooth runout tolerances on planetary gearsets maintain quiet operation inside the passenger compartment.
• 190 lbs bare casing weight matches factory floorpan mounts without requiring custom bracket modifications.
• High-frequency pulse-width modulated solenoids respond within 38 milliseconds to execute instant electronic gear transitions.
• Dynamically balanced torque converter dampens V12 engine rotational harmonics before reaching the driveline.

V12 Hydraulic Torque Thresholds

Operating line pressures range from 235 to 295 PSI to clamp friction clutch packs firmly without slippage during full V12 acceleration. The internal gearset provides a 4.17:1 first gear ratio for brisk vehicle launches, stepping down through intermediate ratios to a 0.69:1 highway overdrive. Continuous input torque ratings peak at 480 lb-ft at 3,900 RPM under severe commercial fleet duty cycles. Auxiliary cooler circuits disperse 500 BTU per minute of heat energy, holding fluid sump temperatures between 160°F and 190°F.

V12 Companion Flange Specs

The rear transmission output shaft features a heavy-duty 3-bolt companion flange configured to mate with reinforced rubber flex discs. Companion flange face dial runout measures less than 0.0012 inches total indicator reading to stop vibration from reaching chassis mounts. The mechanical parking pawl locks against 1,500 lb-ft of static reverse torque on steep ramps.

Mechatronic Calibration Maintenance Protocol

Technicians must execute transmission control module electronic adaptation drive cycles after installation to adjust mechatronic solenoid pressure cycles to remanufactured clutch tolerances. Regular fluid sampling detects friction material wear before mechanical damage occurs. This remanufactured transmission is not engineered for quarter-mile drag racing, custom forced induction tuning, or gross vehicle weights exceeding manufacturer towing thresholds.

• Check transmission fluid level through the side inspection port each shift during initial vehicle break-in.
• Drain transmission fluid and replace the pan filter element every 30,000 miles of commercial operation.
• Inspect external transmission oil cooler lines and rubber mounting hardware every 12 months for physical wear.

Flagship V12 Warranty Manifest

This remanufactured transmission includes a 3-Year / 100,000-Mile commercial fleet warranty covering internal gears, shafts, and mechatronic components against defect. The crated package contains one remanufactured transmission unit, a precision balanced torque converter, replacement cooler line seal washers, an installation manual, and a signed dynamometer test sheet.
