M7ZA 1998-1999 Acura CL 3.0L FWD – Remanufactured 4-Speed Automatic Trans

Description

Meet strict commercial transport fleet maintenance benchmarks with 178 lbs of dyno-certified drivetrain engineering that directs 200 lb-ft torque through four computer-controlled forward gear ratios in the Acura M7ZA Remanufactured Transaxle Unit tailored for 1998 to 1999 Acura CL luxury coupes with 3.0-liter V6 engines.

Constructed with an aluminum three-shaft casing layout, this transaxle maintains exact gear centerlines under peak engine loads. Re-engineered valve body tracts utilize drop-in steel bore liners that eliminate hydraulic pressure drop-off during warm idle conditions. The gearbox holds 7.4 quarts of Honda ATF DW-1 fluid, weighs 178 lbs dry, and includes threaded exterior cooler connection ports.

Key Features of Acura M7ZA

Professional repair centers buy Acura M7ZA remanufactured transmission systems to cure chronic second-gear shudder and delayed engagement issues. Technicians verify line pressures across every gear ratio on advanced computer dyno test stands before crating.

• Hard-anodized pressure regulator sleeves prevent pressure drops during high-temperature idling.
• High-friction clutch linings provide quick lockup without slipping under full vehicle loads.
• Computer-matched linear shift solenoids guarantee smooth forward gear progression.
• Dyno load testing proves Acura M7ZA remanufactured transaxle hydraulic integrity.
• Furnace-brazed torque converter impeller fins eliminate vibration at sustained highway speeds.
• Full-flow internal fluid filters catch particulate matter before it reaches shift valves.
• Precision roller bearings maintain countershaft alignment under rapid acceleration.

Hydraulic Line Pressure Gear Ratios

Main line pump circuits generate 125 to 140 PSI to lock internal clutch discs without slippage under 200 lb-ft continuous input torque at 5,000 RPM. Sump fluid heat stays between 165°F and 190°F through vehicle heat exchangers rejecting 390 BTU per minute. Gear ratios deliver 2.533:1 first, 1.483:1 second, 1.028:1 third, and 0.707:1 fourth gear for maximum highway refinement.

Differential Axle Spline Interface

Precision broached differential gears accept 28-spline CV axle stubs with dual-lip spring seals stopping fluid leaks. Bell housing flanges align flush to Honda J30A1 engine blocks using standard dowel sleeves. Converter hub dial indicator runout remains below 0.002 inches to ensure long front pump seal durability.

Hydraulic Circuit Service Procedures

Proper electrical ground connections ensure consistent pulse commands reach linear shift control solenoids. This transmission is not engineered for competitive track drifting or vehicle loads exceeding gross vehicle weight limits. Following recommended fluid service preserves valve body bores and clutch pack health.

• Check transmission fluid level via the dipstick tube every 50 hours of driving.
• Perform drain and refill using approved Honda ATF DW-1 every 30,000 miles.
• Inspect transmission cooler lines and radiator tank fittings every 12 months.
