1. AUTOMATIC TRANSMISSION FLUID CHECK
2. AUTOMATIC TRANSMISSION FLUID REPLACEMENT
3. FLUSHING COOLERS AND TUBES
When a transaxle failure has contaminated the fluid, the oil cooler(s) must be flushed. The cooler bypass valve in the transaxle must be replaced also.
The torque converter must also be replaced with an exchange unit. This will ensure that metal particles or sludged oil are not later transferred back into the reconditioned (or replaced) transaxle.
There are two different procedures for flushing coolers and lines. The recommended procedure is to use the special tool MB995062 Flushing tool. The other procedure is to use a hand suction gun and mineral spirits.
WARNING: WEAR PROTECTIVE EYEWEAR THAT MEETS THE REQUIREMENTS OF OSHA AND ANSI Z87.1 - 1968. WEAR STANDARD INDUSTRIAL RUBBER GLOVES.
KEEP LIGHTED CIGARETTES, SPARKS, FLAMES, AND OTHER IGNITION SOURCES AWAY FROM THE AREA TO PREVENT THE IGNITION OF COMBUSTIBLE LIQUIDS AND GASES. KEEP A CLASS (B) FIRE EXTINGUISHER IN THE AREA WHERE THE FLUSHER WILL BE USED.
KEEP THE AREA WELL VENTILATED.
DO NOT LET FLUSHING SOLVENT COME IN CONTACT WITH YOUR EYES OR SKIN: IF EYE CONTAMINATION OCCURS, FLUSH EYES WITH WATER FOR 15 TO 20 SECONDS. REMOVE CONTAMINATED CLOTHING AND WASH AFFECTED SKIN WITH SOAP AND WATER. SEEK MEDICAL ATTENTION.
Cooler Flush Using Special Tool MB995062
1. Remove cover plate filler plug on the special tool MB995062.
Fill reservoir 1/2 to 3/4 full of fresh flushing solution. Flushing solvents are petroleum based solutions generally used to clean automatic transmission components. DO NOT use solvents containing acids, water, gasoline, or any other corrosive liquids.
2. Reinstall filler plug on the special tool MB995062.
3. Verify pump power switch is turned OFF.
Connect red alligator clip to positive (+) battery post. Connect black (-) alligator clip to a good ground.
4. Disconnect the cooler lines at the transmission.
NOTE: When flushing transmission cooler and lines, ALWAYS reverse flush.
5. Connect the BLUE pressure line to the OUTLET (From) cooler line.
6. Connect the CLEAR return line to the INLET (To) cooler line.
7. Turn pump ON for two to three minutes to flush cooler(s) and lines. Monitor pressure readings and clear return lines. Pressure readings should stabilize below 138 kPa (20 psi) for vehicles equipped with a single cooler and 208 kPa (30 psi) for vehicles equipped with dual coolers. If flow is intermittent or exceeds these pressures, replace cooler.
8. Turn pump OFF.
9. Disconnect CLEAR suction line from reservoir at cover plate. Disconnect CLEAR return line at cover plate, and place it in a drain pan.
10. Turn pump ON for 30 seconds to purge flushing solution from cooler and lines. Turn pump OFF.
11. Place CLEAR suction line into a one quart container of DIAMOND ATF SP-II, DIAMOND ATF SP-II M or equivalent automatic transmission fluid.
12. Turn pump ON until all transmission fluid is removed from the one quart container and lines. This purges any residual cleaning solvent from the transmission cooler and lines. Turn pump OFF.
13. Disconnect alligator clips from battery. Reconnect flusher lines to cover plate, and remove flushing adapters from cooler lines.
4. OIL COOLER FLOW CHECK
After the new or repaired transmission has been installed, fill to the proper level with DIAMOND ATF SP-II, DIAMOND ATF SP-II M or equivalent automatic transmission fluid. The flow should be checked using the following procedure:
1. Disconnect the cooler line at the transmission and place a collecting container under the disconnected line.
CAUTION: With the fluid set at the proper level, fluid collection should not exceed one quart of internal damage to the transmission may occur.
2. Run the engine at curb idle speed, with the shift selector in neutral.
3. If fluid flow is intermittent or it takes more than 20 seconds to collect one quart of ATF, replace the cooler.
4. If flow is found to be within acceptable limits, reconnect the cooler line. Then fill transmission to the proper level, using the approved type of automatic transmission fluid.
5. OIL FILTER REPLACEMENT
1. Use the special tool (MB991610) to remove the automatic transaxle oil filter.
2. Clean the transaxle case side mounting surface.
3. Apply a small amount of automatic transmission fluid to the O-ring of the new oil filter.
4. Use the special tool (MB991610) to install the automatic transaxle oil filter.
NOTE: Tightening torque: 12 Nm (9 ft. lbs.)
5. Check the quantity of the automatic transmission fluid.
6. THROTTLE POSITION SENSOR ADJUSTMENT
7. PARK/NEUTRAL POSITION SWITCH CONTINUITY CHECK
8. PARK/NEUTRAL POSITION SWITCH AND CONTROL CABLE ADJUSTMENT
1. Set the selector lever to the "N" position.
2. Loosen the control cable to manual control lever coupling nut to free the cable and lever.
3. Set the manual control lever to the neutral position.
4. Loosen the park/neutral position switch body mounting bolts and turn the park/neutral position switch body so the hole in the end of the manual control lever and the hole (cross section A-A in the figure on the left) in the flange of the park/neutral position switch body flange are aligned.
5. Tighten the park/neutral position switch body mounting bolts to the specified torque. Be careful at this time that the position of the switch body is not changed.
6. Gently pull the transaxle control cable in the direction of the arrow, and then tighten the adjusting nut.
7. Check that the selector lever is in the "N" position.
8. Check that each range on the transaxle side operates and functions correctly for each position of the selector lover.
