2002 Dodge Durango

2002 Dodge Durango R/T 5.9 L

Won’t engage on turn-over (Unless I put foot on gas pedal, & then have to hold it in or dies…..sometimes if I rev really hard a few times will then stay Idle but only in Park. If I try & drive it around block to charge battery up it’ll just quit) This just started to happen
Before I was noticing that my transmission is not engaging at proper RPM…. I can manually get 1st-2nd at 2.5 RPM but 2nd-3rd will do it auto…… I can’t do a fast speed climb either….transmission won’t grab with accelerator down …..? Thanks a lot.
