M7ZA 1997 Acura CL 3.0L FWD – Remanufactured 4-Speed Automatic Trans

Description

Across grueling 12-hour corporate shuttle routes demanding continuous stoplight acceleration cycles, internal multi-disc friction plates hold 135 PSI hydraulic clamp pressure without slip inside this Acura M7ZA Remanufactured Automatic Transmission engineered for 1997 Acura CL luxury coupes powered by 3.0-liter SOHC V6 engines.

A high-tensile die-cast aluminum transaxle case encapsulates an advanced three-shaft design that isolates gear loads and maintains bearing alignment. Re-machined valve bodies incorporate steel sleeves to stop hydraulic fluid cross-leakage between circuit passages. Sump capacity requires 7.4 quarts of Honda ATF DW-1, dry weight measures 178 lbs, and fluid cooler lines connect via standard 3/8-inch inverted flare ports.

Key Features of Acura M7ZA

Fleet operators buy Acura M7ZA remanufactured transmission transaxles to eliminate converter shudder and erratic shift timing in corporate vehicles. Every unit undergoes automated dyno testing to verify solenoid current draw and clutch circuit reaction times.

• Hard-anodized valve bore sleeves eliminate internal hydraulic fluid pressure loss.
• Carbon-metallic lockup clutch plates stop torque converter shudder under moderate throttle.
• Calibrated linear shift solenoids eliminate harsh garage shifts between park and drive.
• Spin load testing proves Acura M7ZA automatic transaxle hydraulic integrity.
• Micro-finished planetary reaction plates distribute heat dissipation during stoplight transit.
• Reinforced countershaft roller bearings resist deflection under continuous V6 engine torque.
• Magnetic transmission case drain plug isolates metallic wear particles from the pump inlet.

Hydraulic Operating Thresholds Torque Limits

This four-speed unit operates with main line pressures ranging from 125 to 138 PSI to ensure slip-free clutch plate clamping under 200 lb-ft continuous input torque at 5,000 RPM. Auxiliary cooling systems maintain fluid temperatures between 165°F and 188°F. Gear ratios deliver 2.533:1 first, 1.483:1 second, 1.028:1 third, and 0.707:1 fourth gear for smooth highway cruising.

Front Axle Spline Fitment

The internal differential accepts 28-spline front CV axles with high-grade fluoroelastomer oil seals preventing output leaks. The bell housing bolts flush to Acura J-series 3.0-liter V6 engine blocks. Torque converter pilot runout holds within 0.002 inches, preventing high-RPM vibrations from reaching the passenger compartment.

Transmission Solenoid Maintenance Controls

Shift timing depends on clean linear solenoid screens to regulate hydraulic servo application circuits. This automatic transaxle is not engineered for track time-attack racing or towing loads exceeding vehicle chassis ratings. Regular maintenance preserves clutch friction surfaces and valve bore seals.

• Inspect fluid level on the indicator dipstick every 50 hours of operation.
• Drain and replace automatic transmission fluid every 30,000 miles.
• Inspect linear shift solenoid screens for debris accumulation every 12 months.

Commercial Warranty Crate Inventory

Protected by a 3-Year / 100,000-Mile commercial fleet warranty, this transaxle ships inside a high-density molded crate. Package contents include the remanufactured transaxle unit, precision balanced torque converter, cooler line washers, vehicle-specific installation guide, and dynamometer verification test sheet.
