Check Transmission Fluid Level and Quality

Ensure fluid is at the hot full mark and not burnt or black. on the Mercedes-Benz GLE equipped with 2.0L Turbo / 3.0L Turbo I6 (GLE 450 375HP) / 4.0L V8 GLE 580.

Required Tool: Dipstick, White Paper Towel
02
Monitor TCC Slip RPM on Highway Test Drive

Monitor TCC Commanded vs TCC Slip RPM on scanner at 60 mph. With lockup engaged, slip RPM should be under 20 RPM. If slip remains 200–600 RPM, clutch is not locking. on the Mercedes-Benz GLE equipped with 2.0L Turbo / 3.0L Turbo I6 (GLE 450 375HP) / 4.0L V8 GLE 580.

Required Tool: OBD-II Scan Tool with Live Transmission Data
03
Perform Transmission Fluid & Filter Flush

Replace transmission fluid and filter. In many cases, fresh fluid with new friction modifiers frees a sticky TCC solenoid valve. on the Mercedes-Benz GLE equipped with 2.0L Turbo / 3.0L Turbo I6 (GLE 450 375HP) / 4.0L V8 GLE 580.

Required Tool: Drain Pan, OEM Fluid, New Filter
04
Replace TCC Solenoid on Valve Body

Drop transmission oil pan, remove valve body cover, test solenoid resistance (typically 10–20 ohms), and replace faulty TCC solenoid. on the Mercedes-Benz GLE equipped with 2.0L Turbo / 3.0L Turbo I6 (GLE 450 375HP) / 4.0L V8 GLE 580.

Required Tool: Torx Sockets, Multimeter, Replacement Solenoid
05
Clear Codes and Verify Lockup

Clear DTCs and test drive on highway to confirm lockup engagement. on the Mercedes-Benz GLE equipped with 2.0L Turbo / 3.0L Turbo I6 (GLE 450 375HP) / 4.0L V8 GLE 580.

Required Tool: OBD-II Scanner
