Condition:
Some customers may comment on an automatic transmission fluid leak. Upon further investigation, the technician may find fluid leaking from the oil
pump or bell housing area. This leak may be very slight with only dampness of one or two drops of ATF observed at the bottom of the bellhousing.
Possible Cause:
Investigation of 2006 transmissions has shown small scratches or cuts in the torque converter hub-to-pump seal. These scratches or cuts may be caused
by small burrs on the torque converter hub, pump drive slots.
