Good afternoon and welcome to JustAnswer!!

My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help.

Is the check engine light on and if yes then do you know what codes are setting?

Does it have a code for the output sensor which you replaced?

How does the fluid look and smell?

And are you going to be doing the repairs or are you just looking at what could be wrong?

Talk soon,

No check engine light, fluid is clean not burnt, Might do repairs depends on complication of repair

Good morning..

When you say the transmission is shifting erratically which gears are you having issues with? 1-2, 2-1, 2-3, etc? The most common issue we see is the governor pressure sensor and solenoid failing causing the transmission not to go into 1st when coming to a stop or going from 1st to 2nd then back to 1st and then to 2nd which we call 1-2 shift hunt and to repair this issue you will need to replace the governor pressure transducer and governor pressure solenoid. I attached a picture to help
