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.

Scan it and see if it is the solenoid. No sense buying an electronic item (usually non returnable item at most parts stores) if its not the issue. These transmissions did have solenoid issues though.
Also make sure the wiring connectors are clean and tight.
