Manual Transaxle

Print

Only front wheel drive and 4-wheel drive vehicles are equipped with a manual transaxle; rear wheel drive vehicles are equipped with a transmission.

FLUID RECOMMENDATIONS



Add SAE 90 EP gear oil if the temperature is above 0°F (-18°C); add SAE 80 EP gear oil or ATF (M2C33 or Dexron®II) if the temperature is below 0°F (-18°C).

LEVEL CHECK



See Figures 1, 2 and 3

Checking and replenishing the manual transaxle fluid is accomplished by removing the speedometer driven gear from the top of the transaxle case. Checking the transaxle oil is not required as routine maintenance (it is changed at 30,000 mile or 48,309 km intervals). However, if you suspect leakage, you might want to check fluid level as a precaution.

  1. Park the vehicle on level ground and block the wheels.
  2.  
  3. Remove the speedometer cable from the gear assembly by unscrewing the knurled fitting.
  4.

  1. Unbolt and remove the speedometer driven gear. Pull the gear case upward to remove it from the housing, or use a flat-tipped screwdriver to pry it loose.
  2.  
  3. The oil level should cover the gear and gear shoulder. On 1988-89 626s and MX-6s with turbocharged engines, use the level marks located on the upper portion of the speedometer driven gear (please refer to the illustration).
  4.  
  5. Add gear oil, if necessary, through the speedometer gear mounting hole.
  6.  
  7. Reinstall the speedometer driven gear. Reconnect the speedometer cable.
  8.  
  9. Unblock the wheels.
  10.  

DRAIN AND REFILL



Under "normal" operating conditions, manual transaxle fluid is to be changed at 30,000 mile (48,309 km) intervals. Proceed in the following manner:

  1. Park the vehicle on level ground and block the wheels.
  2.  
  3. Unscrew and remove the speedometer cable/driven gear assembly from the top of the transaxle.
  4.  
  5. Place a large, flat container of sufficient capacity under the transaxle drain plug. Remove the plug from underneath the car.
  6.  
  7. After the oil has completely drained, install the drain plug and tighten it.
  8.  
  9. Add fluid meeting API specifications GL-4 or GL-5. See the Capacities chart for the amount. Check the level by reinserting the speedometer driven gear. The level is correct when the gear is entirely covered with lube oil, but the level does not exceed the level of the ridge slightly above the top of the gear. On 1988-89 turbocharged 626s and MX-6s, use the level marks on the upper portion of the speedometer drive gear to determine the proper oil level (please refer to the illustration).
  10.  
  11. Add further fluid if necessary and reinstall the cable/gear unit into the case.
  12.  
  13. Remove the drain pan and unblock the wheels.
