Sounds like it wasn't re-set properly after it was installed. Take it back and have it double checked.

What wasnt properly re set?

Checked all the fuses...they are all good....man this sucks!


The transmission has to have the system reset plus it has to have all the linkage adjusted properly to make sure the computer is getting the proper signals from transmission selector switch, if it is not set correctly you can loose gears, usually overdrive and sometimes reverse but not always.

So how do you reset the system?...and thanks by the way for the help


If you have a good live data scanner and the knowledge you can set the sensors and switches up yourself, but if you don't have one then let the pros do it or you will mess it up big time.

I had it scanned yesterday and everything is working as it should except the thermostat sensor....it was reading -9. Is this a sensor that is easy ti replace?


Yes it is, it's right in the intake manifold really close to the thermostat housing.

So I dont have to drop the tranny pan?...the mechanic I went to said that you have to drop the tranny pan to get to it


That's where the thermostatic temp sensor is for the engine, now if you mean the one for the tranny temperature sensor, (a transmission doesn't have a thermostat) then yes you will have to drop it to gain access to it, sorry I don't have a picture of where that one is exactly. Just make sure your getting tthe two confused. But you could always do a search on the Internet for exact location.

according to the scan it is the tranny temp sensor which is making it not shift into OD...But they dont know when they look it up what part it is and I cant find a picture online


Here's one.

Just talked to a Mopar Expert that said it is a combination temp/govenor solenoid and easy fix


I do know why when it tranny was overhauled they didn't replace those items, just seem wrong to me.

Yea, me too...around 185$ to fix
