Losing power when shifting up??


my ’08 JKU with auto tranny has been acting funny. It’s feels as though im towing something even thought i’m not. When im accelerating to get into 3rd gear (like when going up a steep hill or getting on the freeway) that the rpms will climb steadily to about 2500 where it’ll get stuck there for a few seconds before shooting up to 4000 and then going back down. All the while this is happening my jeeps speed is still increasing. also now i have to actually tap the gas pedal to roll my jeep out of my garage when before i just had to put it in drive and it would roll out on its own. i do have a lift and 35’s with stock gears, however these have been installed for a while and i’ve already used a flashcal to recalibrate the speedo. HOWEVER about a week ago i ran out gas while on the road could this have something to do with it?

– I’ve got 2 videos of this happening on my youtube channel here are the links:
