I have a 99 XJ sport 4wd with an auto transmission. Approx 175K miles on it. I have notice a significant difference in how the trans ‘downshifts’ when going up a hill in the summer when the weather is warmer. I have never had the bands adjusted (is that a thing on the xj?). The trans fluid looks good. The kick down appears to be adjusted correctly. Any ideas as to what I should look at?

First off, that cable needs to be adjusted. It can't "appear" correctly adjusted.
Video link below on how to do it. takes 2 minutes to do.

Do a drain and fill on the trans using Dex?Merc fluid. buy a gallon and you'll have plenty.

I have done that adjustment before and it didn’t seem to make a difference. I will be doing a tranny service in the near future. It has been 50K of stop and go SoCal traffic since my last fluid and filter change.

Well, 30,000 is the recommended interval for normal service and 15,000 miles for heavy duty service.

Near future for sure. You're long overdue!!!!

So i did the adjustment like the video showed. Haven’t seen much difference. Is ther a way to’flush’ the trans so i can get as much of the old fluid out as possible? I know the trans holds way more fluid than what comes out when you dump it. Maybe do a drain and fill once or twice in a short period of time prior to doing the full service?

Just do a couple of drain and fills.
