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.
Replace Transmission Cooler Return Filter if it Has "AB" Suffix on Jeep Grand Cherokee

On cold start when the transmission goes closed loop (this is a few minutes into driving) the transmission will stall the engine when coming to a stop. At that time there is also delayed engagement, the stall is due to delayed disengagement. After changing the transmission filters (after I read this link) the stalls no longer occur and engagement is normal. Thanks! This advice was right on...
