Replace Transmission Cooler Return Filter if it Has "AB" Suffix on Dodge Ram 1500

If the transmission delays initial gear engagement after being parked overnight or longer, it may be due to a suspect transmission cooler return filter. If the transmission was recently serviced and the part number for the cooler return filter contains an "AB" suffix at the end, a new filter should be installed.
