I had a customer come into my job today with a 98 Town and country with a 3.8 that "would not shift back to 4th after kicking down to climb a grade, even when the gas pedal was brought to idle." I dont know where to start except to recommend a fluid and filter replacement (ATF+4 I know ;P ) would there be anyway to access any transmission fault codes? My store does not have a DRB3 scan tool unfortunately.
As always appreciate any input
