41TE minivan transmission question

one more question. My fluid change didnt change my trans behavior. It sort of hunts between 3/4 for a second under moderate load but after its in OD its fine. Wife is all in a huff about it and wants to dump it for a newer one, but I dont want to get rid of it with an issue that maybe I can fix. could it be the solenoid pack, dirty screens? Nice and easy to unbolt and R&R right up on top.
