Important. For the full load test, apply the handbrake and depress the footbrake. Because of the risk of overheating at full load, do not test for longer than 5 seconds. Pause to allow cooling down. Transmission fluid level must be correct

  1. 1. Remove lower engine compartment cover
  2. 2. Unscrew bolt "D" (1)
  1. 3. Attach KM-6329 (2) to connection "D"
  2. 4. Attach fluid pressure gauge • Attach KM-498-B (1) to KM-6329
  1. 5. Check fluid temperature • Connect TECH 2 – Remove front ashtray • Select menu item "Transmission fluid temperature"

Important. Fluid temperature must be between 50° and 80°C.

Important. For the full load test, tighten the handbrake and depress the footbrake. Because of the risk of overheating at full load, do not test for longer then 5 seconds, then pause to allow cooling down.

  1. 6. Check fluid pressure in selector lever position "D" • Start the engine • Shift selector lever to position "D" • Check fluid pressure when idling and under full load - air conditioning and lighting should be switched off – Idle value should be: 3.7 - 4.1 bar – Full load value should be 13.5 - 14.6 bar • if fluid pressure is outside the desired range, replace transmission • after the check, switch off the engine
  2. 7. Remove fluid pressure gauge • Detach KM-498-B from KM-6329
  3. 8. Detach KM-6329 from connection "D"
