722.6 1998-2002 Mercedes-Benz E430 4.3L RWD – Remanufactured 5-Speed Automatic Trans

Description

Propelling rear-wheel-drive executive sedans across demanding highway routes with 295 lb-ft torque handling at 260 PSI pump force, this Mercedes-Benz E430 Remanufactured Transmission restores refined gear shifts for 1998 to 2002 Mercedes-Benz E430 4.3L models. Fleets gain dependable gear engagement under continuous executive passenger transit service.

Die-cast magnesium-aluminum casing construction eliminates housing deflection under heavy throttle demands. Micro-polished separator plates pair with updated Sonnax pressure regulator valve sleeves to halt hydraulic pressure decay within clutch circuits. High-energy friction plates feature radial cooling grooves that evacuate thermal energy into 8.5 quarts of MB 236.14 transmission fluid. Operating at a dry weight of 178 lbs, this unit integrates dual 3/8-inch cooler ports for sustained cooling balance.

Key Features of Mercedes-Benz 722.6

Torque converter clutch shudder during highway cruising prompts fleet supervisors to buy Mercedes-Benz 722.6 remanufactured transmission units. Recalibrated electro-hydraulic valve bodies with new conductor plates restore precise shift timing across extended commercial fleet duty cycles.

• A 3.59:1 first gear ratio multiplication delivers refined vehicle departure acceleration from stationary stops
• Tolerances inside the precision-machined planetary carrier remain under 0.0025 inches to halt gear whine
• Operating friction circuits use carbon-metallic plates that resist glazing during high-heat operation
• Channeling fluid through remanufactured valve bodies stops shift hesitation between second and third gears
• Severe fleet usage requires the Mercedes-Benz 722.6 package to maintain consistent line pressure stability
• Upgraded electronic conductor plates eliminate speed sensor circuit faults under continuous operation
• Computerized dyno hydro-pulse testing verifies solenoid pressure response curves prior to crate packaging

Hydraulic Line Pressure Calibrations

A 3.59:1 first gear step transitions through five forward ratios toward a 0.83:1 overdrive step that drops highway engine revolution counts. Operating clutch fluid circuits maintain 180 to 260 PSI pump pressure to stop internal slip during heavy acceleration events. Internal transmission fluid temperatures stay stabilized between 160°F and 190°F during long interstate hauls. Fluid circuits push 830 BTU per minute of heat energy straight toward the external cooling unit. Continuous input torque ratings withstand 295 lb-ft at 4,500 RPM without internal gear deflections.

Driveline Flange Spline Alignment

Transferring engine rotation straight through a heavy-duty companion flange, the precision output spline resists driveline lash. High-tensile alloy case construction prevents bearing pocket deformation during severe load changes. Internal parking pawl mechanisms hold 1,500 lb-ft of static rollback torque on 18-degree loading docks. Precision dial indicators measure total output flange runout under 0.0025 inches total indicator reading.

Transmission Adaptation Maintenance Protocols

Command instantaneous electronic gear engagement through complete TCM adaptive shift relearn sequences following mechanical installation. This transmission is not engineered for track drag racing, extreme rock crawling, or gross combined vehicle weights exceeding factory chassis tow limits.

• Each shift scan electronic transmission codes using professional diagnostic scanners to confirm zero conductor plate faults
• Every 30 days check fluid level on level ground at 175°F using the dedicated dipstick tool
• Every 30,000 miles drain contaminated MB 236.14 fluid and replace pan filter elements to protect internal valve sleeves

Commercial Fleet Crate Package

Uninterrupted fleet mobility is backed by a 3-Year / 100,000-Mile commercial fleet warranty covering parts plus labor nationwide. Every secure shipping crate contains one fully remanufactured transmission unit, a balanced torque converter, cooler line seal washers, installation instructions, plus verified dynamometer test printouts.
