When it was battery saver mode it will only stay in one gear.

Yes it's a 2011 dodge journey awd.

Approx 3 weeks ago battery saver light came on while driving home. All warning lights came on shortly after (20minutes)into drive. Car started losing gear. Made it home. Had alternator checked by two different places. Says its fine. Had battery replaced. Was ok for one day then it happened again after sitting overnight. Currently waiting for tow as it wont start after picking kids up from school. (2min trip). What is wrong???? Any ideas would be helpful.
