Can you add stop leak to it? Heard no after i did it. Now whinning noise but cant tell if transmission or wheel hub bearing. No warning light so they said couldnt diagnose it.
Can ATF+4 be substituted for ATF+3? 2000 Jeep Grand Cherokee 4.7l 2wd automatic. 220k miles.
Yes, ATF +4 can be used to replace ATF +3;
"NOTE: ATF+4® is backward compatible with ATF+3 , ATF+2, and ATF+. Additionally,
ATF+4® can be used to top off vehicles that used ATF+3, ATF+2, or ATF+."
This is the service bulletin:

I have even used Walmart’s Syntech ATF+4 in my Chrysler’s with no ill effects.
