The correction kits are really the best single, or first step. There are many factory defects with virtually every transmission Ford has ever made. I don't mean things which warrant a recall, just little odd symptoms which people generally live with. Dealers generally describe all of those symptoms as normal, and most people accept that.
There have always been improvements by manufacturers, year after year, for every transmission. Ford is notorious for creating bad reputations for its automatic transmissions. The problems all originate in first versions of each new tansmission. Once in a while Ford actually crates some dealer fixes, which are applied if a customer complains enough. Check with Ford, and you will discover several Ford upgrade kits for these Explorer V6 automatics.
TransGo continously researches any and all transmission complaints, odd symptoms, etc. They develop kits to correct those deficiencies, without trying to criticize the manufacturers. They simply build them, and make them available through any trans parts outlet.
If TransGo makes an inexpensive kit for you're transmission(about $30-40), then there are symptoms with your transmission which waranted making the kit. That kit will do more for the reliability and driveability, than any electronic gadget, or chip, etc.
No offense intended, but it would always be wiser to attend to internal issues, than to play with just some small characteristic, shift, etc. As expensive as transmissions are to work on, first priority should always be to increase reliability, lifespan, driveability, and not "make the shifts harder."
