Limit sample of fines in auto fluid |
Criteria
: Metallic sound is heard at the torque converter during stall test or in neutral.
: 1-way clutch is free in both directions or locked.
: Auto fluid contains fines in amounts greater than the limit sample (see the limit sample)
NOTE:
·The limit sample of fines in auto fluid is approx. 0.025 L {0.026 US qt, 0.022 lmp qt} of auto fluid drawn from the removed torque converter to a petri dish.
·For the limit sample of fines in auto fluid, refer to “Notes packaged with rebuilt A/T”.
·For the limit sample of fines in auto fluid, refer to “Notes packaged with rebuilt A/T”.
(3) Replacement of auto fluid in torque converter
(a) If auto fluid has an unusual odor and is discolored, thoroughly stir the auto fluid in the torque converter and draw the auto fluid with the installing surface facing upward.
(4) Check of oil cooler and oil pipeline cleaning
(a) When checking the torque converter and filling auto fluid, clean the oil cooler and the pipeline.
NOTE:
Clean by blowing 196 kPa {2.0 kgf/cm2, 28.4 psi} of compressed air from the inlet hose.
(b) If the auto fluid or the coolant is cloudy, check the oil cooler.
(5) Prevention of torque converter deformation and oil pump gear damage
(a) If interference marks are found at the end of the torque converter installation bolt and the bottom of the torque converter installation hole, replace the bolt and the torque converter.
