Automatic Transaxle

FLUID RECOMMENDATIONS



All automatic transaxles, use Dexron III®ATF (automatic transmission fluid).

LEVEL CHECK



See Figures 1, 2 and 3

The fluid level in the automatic transaxle should be checked every 12 months or 15,000 miles, whichever comes first. The transaxle has a dipstick for fluid level checks.

  1. Drive the vehicle until it is at normal operating temperature. The level should not be checked immediately after the vehicle has been driven for a long time at high speed or in city traffic in hot weather. In those cases, the transaxle should be given a 1 / 2 hour to cool down.
  2.  
  3. Stop the vehicle, apply the parking brake, then shift slowly through all gear positions, ending in P . Let the engine idle for about 5 minutes with the transaxle in P . The vehicle should be on a level surface.
  4.  
  5. With the engine still running, remove the dipstick, wipe it clean, then reinsert it, pushing it fully into the tube.
  6.  
  7. Pull the dipstick again and, holding it horizontally, read the fluid level.

  1. Cautiously feel the end of the dipstick to determine the temperature. Note that on Nissans there is a scale on each side, HOT on one, COLD on the other. If the fluid level is not in the correct area, more will have to be added.
  2.  
  3. Fluid is added through the dipstick tube. You will probably need the aid of a spout or a long necked funnel. Be sure whatever you pour through is perfectly clean and dry. Use an automatic transmission fluid marked Dexron III®. Add fluid slowly, and in small amounts, checking the level frequently between additions. Do not overfill, which will cause foaming, slippage or possible transaxle damage. It takes only 1 pint (473mL) to raise the level from L to H when the transaxle is hot.
  4.  

DRAIN & REFILL



See Figures 4, 5 and 6

It is recommended that the automatic transmission fluid be changed every 30,000 miles if the vehicle is used in severe service. You may also want to change it if you have bought your vehicle used and are unsure of the last time it was changed.

  1. Raise the car and support it securely on jackstands.
  2.  
  3. Place a large drain pan under the transaxle.
  4.  
  5. Loosen the drain plug on the transaxle. Unscrew the drain plug from the pan by hand while pushing inward. When the threads are free, quickly pull the drain plug away and drain the fluid from the transaxle.
  6.  
  7. After the fluid is fully drained, install drain plug. On RE4F04 models, the copper gasket should be replaced. Tighten the drain plug to 22-29 ft.lbs. (29-39 Nm.). Do not overtighten the plug, or the threads may be stripped, requiring costly repair.
  8.  
  9. Lower the vehicle from the jackstands.
  10.  
  11. Fill the transaxle with Dexron III®or Genuine Nissan ATF specified for your vehicle until the dipstick registers at the MAX mark.
  12.  
  13. Start the engine and move the gear selector through all gears in the shift pattern. Allow the engine to idle for five minutes.
  14.  
  15. Check the fluid level. Add ATF, as necessary, to obtain the correct level.
  16.  

PAN & FILTER SERVICE



RE4F02 Models

RE4F02 model transaxles use filters which are placed within the valve body inside the transaxle. Changing these filters would require valve body disassembly, which should be performed by a qualified transmission repair shop.

RE4F04 Models

See Figures 7 through 15

Fig. Fig. 15: Use a gasket scraper to clean the old gasket from the pan; always use a new gasket

  1. Raise the car and support it securely on jackstands.
  2.  
  3. Place a large drain pan under the transaxle.
  4.  
  5. Loosen the drain plug on the transaxle fluid pan. Unscrew the drain plug from the pan by hand while pushing inward. When the threads are free, quickly pull the drain plug away and drain the fluid from the transaxle. Discard the drain plug gasket.
  6.  
  7. Using a new gasket, install the drain plug and tighten it to 22-29 ft.lbs. (29-39 Nm.).
  8.  
  9. Loosen all of the pan attaching bolts to within a few turns of complete removal, then carefully break the gasket seal, allowing any excess fluid to drain over the edge of the pan.
  10.  


WARNING
DO NOT force the pan while breaking the gasket seal. DO NOT allow the pan flange to become bent or otherwise damaged.

  1. Remove the pan bolts and carefully lower the pan. Keep in mind there may still be traces of fluid in the pan even though it has been drained.
  2.  
  3. Clean the transaxle oil pan thoroughly using a safe solvent, then allow it to air dry. DO NOT use a cloth to dry the pan, since it might leave behind bits of lint. Discard the old pan gasket.
  4.  
  5. Remove the filter mounting bolts, then remove the filter by pulling it down and off of the valve body. Make sure any gaskets or seals are removed with the old filter.
  6.  
  7. Install the new filter, making sure all gaskets are in place, then secure it with the retaining bolts. Make sure the bolts are installed in their correct locations, as they are different lengths. Torque the bolts to 6.9 -6.5 ft. lbs. (7-9 Nm.).
  8.  
  9. Place a new gasket on the pan, then install the pan to the transaxle. Use new bolts, as they are special self-sealing bolts. Tighten the pan bolts to 6.9 -6.5 ft. lbs. (7-9 Nm.).
  10.  
  11. Remove the jackstands and carefully lower the vehicle.
  12.  
  13. Fill the transaxle, through the dipstick hole, with Dexron III®Automatic Transmission Fluid (ATF) or Genuine Nissan ATF specified for your vehicle.
  14.  
  15. Start the engine and move the gear selector through all gears in the shift pattern. Allow the engine to idle for five minutes.
  16.  
  17. Check the fluid level. Add ATF, as necessary, to obtain the correct level.
