Dodge Ram 1500 Car Problems

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

Problem Description and Solution

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.

When put into gear it takes 5 to 10 seconds to ingauge and start pulling, but once warms up, goes right in gear and pulls fine but at times seems like stays in 3rd gear
same as description in post, and once in gear it seemed like it was in a higher initial gear not low like it should
Slow engaging in the AM after overnight. Took to dealer numerous times no issues found could not repeat. One day the truck would not change gears while in Drive. Took it to dealer and they said filter was installed backwards and clogged. Replaced and installed correctly
