02 ATX stuck in limp mode.

I know there are other topics on this, but most were fixed with replacing the speed sensors, adding fluid or swapping out the solenoid pack.

Added fluid, it was about a half a quart low.

Replaced both VSS, nothing.

Replaced the solenoid pack and nothing... but it did start throwing another code when I did that. It now says my TCM is bad and the rom fails during self test. WTF?

I hope this is just a simple wiring issue or something...

HELP!?

Check your grounds under the hood. Your TCM might just be dead too.. hard to say.

I ran into a similar issue and replaced the vss which didn't do the trick then someone told me to replace the conector and wiring that goes to the vss on the bumper side of the trans and that did the trick. It was like 20 something for the part from dodge. If you want I may even be able to find a part number for you.

Well... I replaced those first. So yeah.

I replaced the tcm and it's all good now.

I just replaced my tranny and I am having this same issue. 02 sxt as well.

gotta look into this TCM thing. that's the module with the 8mm wrench isn't it?

No the thing on top of the tranny you are refering to is the shift sheloid pack, the tcm connects to it, but isnt anywhere near the tranny.

Anwsered this 3 times now for ya lol

Lol weird, I don't see where the TCM connects to it. I'm hearing the passenger winshield resovoir area. I'm going to get a new one today for $25...hope it works
