Upgrade to overdrive
I have a 98 wrangler sport with an automatic tranny. I would like to change the tranny to one that runs better on the highway since I use it daily and need better gas milage. Can anyone recommend what route to take?

AW4 seems to be the preferred option. I'm sure you can find a few write-ups

Thanks, I had a 97 Cherokee I gave my daughter six years ago and it’s still running fine and she got really good milage. I guess after reading the article I’ll have to hunt down a newer one.
