AWF21 2007-2008 Mazda CX-7 2.3L AWD/4WD – Remanufactured 6-Speed Automatic Trans

Description

Through relentless winter transit conditions, holding 258 lb-ft of turbo torque across 280 PSI line pressure protects internal clutch packs from slip. The Mazda AWF21 Remanufactured Transmission supports 2007 to 2008 Mazda CX-7 2.3-liter all-wheel-drive turbo crossovers. Enhanced hydraulic circuitry and hardened planetary gears stop shift hunting during heavy grade climbs across multi-hour municipal delivery schedules.

Die-cast A380 aluminum casing structures protect high-tensile ductile iron planetary carriers and nitrided steel sun shafts. Hard-anodized Sonnax sleeves restore worn valve body channels to stop fluid bypass. Featuring threaded cooler connections and an integrated power transfer mounting face, this 210-pound six-speed transmission holds 8.8 quarts of synthetic fluid and bolts flush to transverse all-wheel-drive subframes without modification.

Key Features of Mazda AWF21

Fleet operators looking to buy Mazda AWF21 remanufactured transmission inventory gain dyno-tested powertrain hardware engineered for severe service. Upgraded hydraulic circuits eliminate common shift slips and prevent friction plate glazing under turbo boost.

• High-energy carbon friction discs maintain positive torque transfer without thermal fade during sudden acceleration
• Sonnax hard-anodized line regulator sleeves stop internal fluid leakage across high-wear valve tracts
• Computerized shift solenoids actuate in 40 milliseconds to execute clean gear changes
• Dynamic balancer systems verify torque converter balance down to 0.04 gram-inches to eliminate driveline vibration
• Carburized planetary gears distribute tooth contact pressure during sudden all-wheel torque transfers
• Precision-ground steel reaction plates maintain uniform clamp force across all forward gears
• Remanufactured AWF21 turbo valve bodies pass rigorous multi-port vacuum testing to verify seal performance
• Fluoroelastomer output seals stop fluid leaks between the transmission case and external transfer unit

Hydraulic Line Pressure Envelope

Internal line pressures cycle between 68 PSI idle baseline and 280 PSI under full turbo acceleration. Continuous input torque ratings handle 258 lb-ft at 4,500 RPM for severe commercial fleet duty. Forward gear reduction ratios provide 4.15:1 first, 2.37:1 second, 1.56:1 third, 1.16:1 fourth, 0.86:1 fifth, and 0.69:1 sixth overdrive. Multi-plate fluid heat exchangers shed up to 22 kW of thermal energy, stabilizing operating sump oil temperature between 165°F and 188°F.

Transfer Unit Spline Dimensions

Internal differential carrier splines mate with 39-tooth transfer unit input shafts for dependable all-wheel-drive power distribution. The heavy park pawl mechanism withstands 1,580 lb-ft of static driveline load on steep loading inclines. Total output hub runout stays below 0.0014 inches dial indicator deflection, eliminating front-end chassis vibration.

Electronic Solenoid Calibration Protocol

Technicians must initiate diagnostic TCM adaptive shift programming after installation to calibrate clutch engagement timers. This transmission unit is not engineered for competitive track racing, extreme off-road mud driving, or vehicle loading beyond factory gross vehicle weight limits.

• Inspect fluid level and clean metallic debris from the pan magnet every 30,000 miles
• Drain fluid sump and replenish with approved synthetic oil every 12 months
• Flush external transmission cooler lines and clean radiator fins every 24 months

Commercial Fleet Warranty Terms

Supplied with a 3-Year / 100,000-Mile commercial fleet warranty, this transmission safeguards vehicle uptime. The sealed transport container contains the remanufactured transmission unit, balanced torque converter, transfer unit seal ring, vehicle-specific setup guide, and verified dynamometer test printout.
