The valve body has failed inside the transmission. . It's possible the shift solenoids or the transmission control module are faulty as well.

Your going to have to get the Jimmy scaned before youhurt the transmission, It sounds like it's on a Limp mode which can range from a tune up to a bad ground. Good luck.

Testimonial: "Thanks for the info. I ended up sell the jimmy and passed on the info to the buyer they also found it helpful."
The brake rlease switch for the gearshift might need adjusted-replaced or the shifter itself might need adjusted
