What is the actual sensor to turn on the diff light on the dash board?  To fix it a new torque converter was replaced.  Not cheap!

Answer -
I suggest you take her down and have someone scan for Diagnostic codes. I looked for an hour and never found anything that mentioned a differential warning light. I am not saying your crazy! LOL Just that I wasn't able to find anything in AllData about it. But if a light is on, there is a code at home. Cottman Transmissions will scan you for free if there is one nearby.

Answer
Scit,

I don't know, like I said, I looked for an hour and nothing in my database talks about a diff light. But if there is a light warning light on yout dash, then there is a code stored, have your car scanned as I mentioned before and give me the code number. Then I can tell you what sensor we need. I am suspecting it's a turbine speed sensor, but please have it checked and let me know. Maybe an Auto Zone can scan it for you and it's free.
