2000 explorer 4wd automatic So the explorer had been driving ok. A week or so ago I had made note that it seems to do a little bit if late shifting in the later gears but nothing that I was worrying about. Yesterday I went out for the day went 2 town over and no issues. I stopped at walmart when I got home and as I left I noticed that from 1st to 2nd gear it was slipping really bad. Instead of shifting at around 1000 where it had been it was going up over 1500. Once I'm up past that though the rest shift ok. I checked the tranny fluid and it was up to level but it looked pretty dirty. I'm hoping that a fluid change and filter change will help limp it along a little longer. Ive been advised not to do an actual flush. What do y'all think? Thanks in advance. I appreciate your time and help.
