CAUTION

  1. Wear work clothing, including a cap, protective goggles and protective shoes during operation.
  2. Remove contamination including dirt and corrosion before removal, installation or disassembly.
  3. Keep the disassembled parts in order and protect them from dust and dirt.
  4. Do not place the oil pan with its inner side facing up until it is installed, to prevent intrusion of foreign matter into the valve body.
  5. Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, installation, disassembly and replacement.
  6. When disassembling the case and other light alloy parts, use a plastic hammer to separate the case. Do not pry apart with screwdrivers or other tools.
  7. Be careful not to burn yourself, because each part on the vehicle is hot after running.
  8. Use SUBARU genuine gear oil, grease etc. or equivalent. Do not mix fluid, grease, etc. with that of another grade or from other manufacturers.
  9. Be sure to tighten fasteners including bolts and nuts to the specified torque.
  10. Place shop jacks or rigid racks at the specified points.
  11. Apply gear oil or ATF onto sliding or revolving surfaces before installation.
  12. Replace deformed or damaged snap rings with new parts.
  13. Before installing O-rings or oil seals, apply sufficient amount of ATF fluid to avoid damage and deformation.
  14. Be careful not to incorrectly install or fail to install O-rings, snap rings and other such parts.
  15. Before securing a part on a vise, place a cushioning material such as wood blocks, aluminum plates, or shop cloth between the part and the vise.
  16. Avoid damaging the mating surface of the case.
  17. Before applying sealant, completely remove the old sealant.
  18. When disassembling the AT, be sure to use nylon gloves and paper towels. Do not use cloth gloves or waste cloth.

GENERAL TOOL CHART

CONDITION CHECK

Note. When replacing ATF, check the inside condition of the transmission body by inspecting the drained ATF.

Fluid conditionTrouble and possible causeCorrective action
Large amount of metallic pieces are found.Excessive wear of the internal of the transmission body.Replace ATF and check if AT operates correctly.
Thick and varnish-form fluid.Burned clutch and etc.Replace ATF and check AT itself and vehicle for faulty.
Clouded fluid or bubbles are found in fluid.Water mixed in fluid.Replace ATF and check the water entering point.

DIAGNOSIS PROCEDURE

GENERAL PRECAUTION

Road tests should be conducted to properly diagnose the condition of automatic transmission.

Note. When performing the test, do not exceed the posted speed limit.

D RANGE SHIFT FUNCTION

Check shifting between 1st <-- --> 2nd <-- --> 3rd <-- --> 4th while driving on normal city streets.

D RANGE SHIFT SHOCK

Check the shock level when shifting up during normal driving.

KICK-DOWN FUNCTION

Check kick-down for each gear. Check the shock level during kick-down at the same time.

LOCK-UP FUNCTION

  1. Check that rpm does not change sharply when the axle pedal is lightly depressed while driving in "D" range on flat roads at 60 km/h (37 MPH).
  2. Check slip lock-up with following procedure. Subaru Select Monitor is required for judgment. Before starting the check, make sure that no DTC is displayed using the Subaru Select Monitor. If there is a DTC, perform the corrective action according to the DTC. Recheck to see that the DTC has been cleared, then start the slip lock-up check.
  1. The check is to be performed on a flat and straight road or on a free roller. NOTE: Slip lock-up will not operate when the vehicle is lifted up off of its wheels, since there is no surface resistance. Even when checking on the free roller, the driving resistance will be slightly inadequate. It will be easier to check if the foot brake is stepped on lightly while performing the judgement.
  2. Connect the Subaru Select Monitor.
  3. Check the ATF temperature using the Subaru Select Monitor. NOTE: Make sure that the ATF temperature is between 50 - 100°C (122 - 212°F). If the temperature is low, warm-up the ATF by running the vehicle.
  4. Start the engine, so that the lock-up duty can be read on the data display of the Subaru Select Monitor.
  5. Drive the vehicle at a constant speed of 35 - 40 km/h (22 - 25 MPH).
  6. Read the lock-up duty while vehicle is running. Specification: 25 - 45%

Note. The reading may be slightly lower on a free roller.

  1. Slip lock-up control is not operating when the lock-up duty is less than 5%, or when the lock-up duty goes down immediately after starting to rise. In these cases, improper ATF or deterioration of the ATF may be the cause. Check the amount of ATF or replace the fluid, then recheck.

CLIMBING CONTROL FUNCTION

  1. Check that the gear remains in 3rd when going uphill.
  2. Check that the gear remains in 3rd when applying the brakes while going downhill.

TRANSFER CLUTCH

Check for tight corner braking phenomenon when the vehicle is moved forward with the steering fully turned.

OIL LEAKS

After the driving test, inspect for oil leaks.

MEASUREMENT

Note. If the clutch or brake shows a signs of slipping or shift feel is not correct, check the line pressure.

  1. Excessive shock during up-shift or if shifting takes place at a higher point than for normal conditions, this may be due to the line pressure being too high.
  2. Slippage or inability to operate the vehicle may, in most cases, be due to insufficient oil pressure for the operation of clutch, brake or control valve.

  1. Line pressure measurement (under no load): Before measuring line pressure, jack-up all the wheels. Maintain the ATF temperature at approx. 70 - 80°C (158 - 176°F) during measurement. (ATF will reach the temperature above after idling the engine for approx. 30 minutes with the select lever in "N" or "P".)
  2. Line pressure measurement (under heavy load): Before measuring line pressure, apply both the foot and parking brakes with all wheels chocked (Same as for "stall" test conditions). Measure the line pressure when the select lever is in "R" and "2" with engine under stall conditions. Measure the line pressure within 5 seconds after shifting the select lever to each position. (If the line pressure needs to be measured again, allow the engine to idle and cool it down for more than 1 minute.) Maintain the ATF temperature at approx. 70 - 80°C (158 - 176°F) during measurement. (ATF will reach the above temperature after idling the engine for approx. 30 minutes with the select lever in "N" or "P".)
  3. Temporarily attach the ST to a suitable place in the driver's compartment, remove the blind plug located in front of the toe board and pass the hose of the ST to the engine compartment. ST 498575400 OIL PRESSURE GAUGE ASSY
  4. Remove the test plug and install the ST instead. ST 498897200 OIL PRESSURE GAUGE ADAPTER
