2010 with a shift flare on 1-2 and 2-3 only when warm Changed servos already. Need direction

[whdahel]

hello everyone, i have been doing alot of reading the past 2 weeks. And I was hoping you guys might be able to help me out.. our 2010 explorer ( 4.0) has recently started to have shift flares when it is warm. I did a bit of reading and figgured it was from worn servo bores. I ordered a kit online from AJ1E Superior Solutions, LLC that has the original style servos with orings on them and installed them along with changing the fluid and filter. Well about 4 days later it starts the flares again, only when warm and not as bad. I don't believe I need a rebuild, but I'm not sure where to start.. possible Valve body?? Do you guys have any insite?? Thanks to all who help!

I tried this . But the servo bores were too worn. Had a complete rebuild done. Part of it was to sleeve the servo bores. They installed several other upgrades/ kits. Better than new. $2800.
