Some customers may comment on an intermittent SES light during light throttle operation.
Upon investigation, technicians may find DTC P0843 stored.
This condition may be caused by the TCC intermittently releasing and re-applying ONLY on a slight upgrade and under light load conditions. This condition will not occur on level road, downgrade or a more aggressive upgrade.
Technicians are to inspect the torque converter O-ring and replace it, if necessary.
If the O-ring is not torn, refer to SI for other possible causes.
