INSPECT TRANSMISSION OIL CLEANER MAGNET

Examine the particles in the automatic transaxle oil pan.

Collect any steel chips with the removed magnets. Look carefully at the chips and particles in the automatic transaxle oil pan and on the transmission oil cleaner magnets to see the type of wear which might be found in the automatic transaxle.

Result

Steel (magnetic)	Brass (non-magnetic)
Bearing, gear and plate wear	Bushing wear

INSPECT INPUT SHAFT END PLAY
1. Using a dial indicator, measure the input shaft end play.

  Standard end play
  
  0.020 to 1.242 mm (0.000788 to 0.0488 in.)
INSPECT INTERMEDIATE SHAFT END PLAY
1. Clean the contact surfaces of the transaxle case and rear transaxle cover.

4. Calculate the end play value using the following formula:
  End play = Dimension B - Dimension A - Thrust needle roller bearing thickness
  
  Standard end play
  
  0.022 to 1.099 mm (0.000867 to 0.0432 in.)
INSPECT PLANETARY SUN GEAR SUB-ASSEMBLY
1. Using a caliper gauge, measure the inside diameter of the bushings of the planetary sun gear.

  Standard inside diameter
  
  25.525 to 25.546 mm (1.00492 to 1.00574 in.)
  
  Maximum inside diameter
  
  25.546 mm (1.00574 in.)
  
  If the inside diameter is more than the maximum, replace the planetary sun gear.
INSPECT REAR PLANETARY SUN GEAR ASSEMBLY
1. Using a caliper gauge, measure the inside diameter of the bushing of the rear planetary sun gear.

  Standard inside diameter
  
  25.580 to 25.601 mm (1.00709 to 1.00791 in.)
  
  Maximum inside diameter
  
  25.601 mm (1.00791 in.)
  
  If the inside diameter is more than the maximum, replace the rear planetary sun gear assembly
INSPECT UNDERDRIVE PLANETARY GEAR ASSEMBLY
1. Using a feeler gauge, measure the clearance between the underdrive planetary gear assembly gear at 4 points.

  Standard clearance
  
  0.18 to 0.54 mm (0.00709 to 0.0212 in.)
  
  If the clearance is more than the standard clearance, replace the underdrive planetary gear assembly.

INSPECT ONE-WAY CLUTCH ASSEMBLY

Temporarily install the one-way clutch assembly to the planetary ring gear.

Make sure that the one-way clutch assembly turns freely counterclockwise and locks when turned clockwise.
If the one-way clutch assembly does not operate normally, replace it.

INSPECT NO. 1 BRAKE DISC
1. Check if the contact surfaces of the No. 1 brake discs, No. 1 brake plates and No. 1 brake flange are worn or burnt.
