Good morning and welcome to JustAnswer!!

My name is ***** ***** I have worked for a Jeep dealership for 18 years and I will do my best to help...

You have a 42RE transmission that uses a Governor pressure transducer to read the pressure so the PCM knows when to shift. The most common thing we see is the sensor fail which will cause this.. The sensor and solenoid run around 100.00 each and installation is easy just drop the pan but the bad news is that diagnosing this issue will require a scantool to monitor the governor pressures... Is the check engine light on and if so what codes are setting?

Talk soon,

Brad
