no...I have to release and allowed it to shift through 2nd and 3rd
Not positive on that trans but I don't think it shifts on a vacuum I believe it is electronic shift so it may be a sensor has gone bad call a autoparts store like AutoZone and ask them if they're scanner may be able to read a code for the trans shift code a lot of the major auto parts store will scan your car for free

I was watching a video on YouTube about shift solenoids. Look this up for your year and model. They are somewhat exposed once the transmission pan is off. I was advised a flush is not the best, but obviously, you will have to replace fluids and pan gasket once removed. This may be the most cost effective repair before a rebuild. I have never done this before, but reviewed the video. please view and decide with discretion. I hope this takes provides a solution for you and your vehicle. Rick
