Mercedes-Benz E 320 1998-2002 Automatic Transmission Manual: Mercedes-Benz E 320 (722.605) Transmission-Guide Automatic Transmission Applications: Mercedes-Benz E 320 (1998-2002) // Transmission Model: 722.664 / 722.607 / 722.623 / 722.662 / 722.605 / 722.622 / 722.620 / 722.621 / 722.605 // Description: Electronically controlled automatic 5-speed with lock-up torque converter. Includes 3 compound planetary gear sets, multiple-disc clutches, multiple-disc brakes, and free-wheeling clutches.

  • Factory Clutch Data: Friction discs require specific clearances for proper operation, with allowable clearances ranging from .028-.067 inches (0.7-1.7 mm) for 3-4 friction plates.
  • Essential Component Specs: The transmission utilizes 3 multiple-disc clutches, 3 multiple-disc brakes, and 2 free-wheeling clutches for planetary gear set control.
  • Key Control Functions: A hydraulic system, pressurized by a crescent gear type pump, provides working pressure for friction elements and automatic controls.
  • Verified Lubrication Specs: The lubricating pressure circuit is designed to cool mechanical transmission parts and limit pressure within the torque converter.
  • Designated Pressure Values: Modulating pressure is adjusted by a modulating pressure regulating solenoid valve and affects working pressure and pressure overlap control valve operation.
  • Approved Shift Specifications: Shift pressure regulates pressure during shifting phases, influencing modulating pressure and the pressure overlap control valve for precise gear engagement.

FAQ

Check the **identification** plate for transmission model codes. keyboard_arrow_down

Identification code is stamped on the transmission housing's identification plate; use this code when ordering parts for your Mercedes-Benz E320.

What are the **necessary** gear ratio specifications? keyboard_arrow_down

Gear ratios vary by selection: 1st gear is 3.59:1, 2nd is 2.19:1, 3rd is 1.41:1, 4th is 1:1, 5th is 0.83:1, Reverse (Standard) is -3.16:1, and Reverse (Winter) is -1.93:1.

Reference the **recommended** fluid specifications for the transmission. keyboard_arrow_down

The hydraulic system uses a crescent gear type pump to provide working pressure for friction elements and automatic controls; always refer to the vehicle's underhood A/C specification label or A/C compressor label for correct fluid type and quantity.
