What happened to mine is it just didn't have the retaining clip at all. So shifting was all over the place. Some days was fine, some days shifted on the hard side, others way to soft. Figured something was up and that's when I found the clip missing (4.0 has just a small white retainer clip, not sure how the 4.7 is). So started playing with it, as it was a known mode on the gen3 camry's. Couldn't get it right so read up on how chry-co said to adjust it. From there it was the normal 'dead zone' my ZJ had. So the light bulb went off, and wondered if I tweaked it what would happen? Ended up with a smooth shift all the way up from a top accelerating to highway speeds. Just seems to behave better. Don't notice sloppy shifts or any slipping, so hopefully all is well with it. I tend to feather the gas though to get it to kick down and drop rpm's when I want as well rather than let it sit at a higher rpm for no good reason. Been doing it since my first XJ. Always find certain speeds when you think it should drop down, it doesn't unless you accelerate and it then does it, or decrease speed. I perfer to stay a constant speed.
The beatings will continue until attitudes improve!
