Great Transmission oil debate

I am new here , new jeep owner, Read all the post before changing my transmission fluid. I was having trouble shifting into 2nd gear and could not downshift. Decided to go with 10W30 Mobile 1 oil in Ax15 transmission ( Per Chrysler recommendations). Now the transmission shifts beautifully into 1,2,3,4 and I can down shift easily. But now it doesn't want to shift into 5th gear after it gets warmed up like half hour of highway driving. it will go in but I need to shift fast from 4th to 5th. if I drop it into neutral then into 5th it wont go doesn't grind just wont go in. any thoughts?

I did the same thing about 5 months ago and it shifts like butter in all gears. Sounds like you may be having other issues. On mine though I could shift through all the gears fine just 2nd was hard to shift into when cold. Good luck!
Violence may not be the answer but it sure cuts down on the stupid questions
