5. Remove turbine revolution sensor (power train revolution sen-
sor) (1) from transaxle case (2).
: Bolt (1)
6. Remove O-ring (3) from turbine revolution sensor (power train
revolution sensor) (1).
7. Remove revolution sensor (1) from transaxle case (2).
: Bolt (2)
8. Set manual shaft (1) in “P” position.
9. Remove PNP switch (2) from transaxle case.
: Bolt (3)
10. Remove oil pan bolts.
11. Remove oil pan and oil pan gasket.
12. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, frictional material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.
If frictional material is detected, clean the A/T fluid cooler
after repair of A/T. Refer to TM-172, "
A/T Fluid Cooler
Cleaning".
13. Remove magnets from oil pan.

18. Apply compressed air into the oil hole as shown, and remove
servo release accumulator piston from transaxle case.
CAUTION:
Strong flow of air will push the accumulator piston out
along with a splash of ATF. Cover the area with lint-free
cloth and blow air little by little to avoid this.
19. Apply compressed air into the oil hole as shown, and remove N-
D accumulator piston and return spring from transaxle case.
CAUTION:
Strong flow of air will push the accumulator piston out
along with a splash of ATF. Cover the area with lint free-
cloth and blow air little by little to avoid this.
20. Remove O-rings (1) from servo release accumulator piston (2)
and N-D accumulator piston (3).
CAUTION:
Wrap the removed servo release accumulator piston (2) and
