SYMPTOM
The customer may experience a more-than-normal delay when shifting into gear the first time after the vehicle sits for
a long time. This may be intermittent.
POSSIBLE CAUSES
Fluid draining from the torque converter when the vehicle sits for a long time (usually overnight) causes the delay
engaging into gear.
CORRECTIVE ACTION
Install the updated transmission lower valve body kit and update the PGM-FI software.
NOTE: You do not need to drop the subframe to replace the lower valve body.
