Good evening 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.

Are you saying that the transmission feels like it's stuck in 1st gear? If you manual shift to second will it shift or are you dealing with a engine issue not rev-ing?

Talk soon,

Brad

feels like in won't shift, stays in low gear manual shifting won't improve it.

Thanks for the reply!!

The 1998 Dodges came with the 46RE transmissions and if it won't shift then there is very good chance there is a code in the engine computer which is the PCM. Is there any way to can connect a code reader and tell me what codes are setting? If you can then I can tell you exactly what is going on and how to fix it, but if you can't then the best thing that I can tell you is that it's most likely a bad governor pressure sensor and solenoid because I have replaced many of them for this exact issue. To replace them you will need to drop the pan and remove them from the underside of the valvebody. No special tools needed only a T25 torx and a 7/16 socket..

But the proper way to diagnose this would be to see what codes are setting, so if you can get the codes post them here and if not then I would try the governor pressure sensor and governor pressure solenoid.. I have attached a picture to show you the location of the sensors and I would also replace the filter while the pan is off and make sure to only use ATF+4 fluid..
