Didn't find anything on first inspection - I got all the sensors from electrical advantage (they sell on ebay and online) and are high rated.
The other unit I have for it looks real nice and may have been rebuilt at the dealer as it has the updated dealer pan gasket but I can't tell if the converter was replaced. It's a chrysler converter with the 9565 tag on it. I may get a Recon to be safe. I will also ask electrical advantage what their warranty/return policy is on sensors!
