sorry this is a BUSY season so slow going getting details.

I am guessing, so correct the below guess.

this is a 3.6L eng and a NAG1 trans..

No recent repairs to instrument cluster ?

Fliud has not been changed recently and fluid level is good.

Once i know what the eng and trans is I will check TSB etc and post.
