I don't think you're having a problem due to the 180 t-stat itself. I
ran a 180 in my 318 in FAR colder temps without any trouble at all.
However, if that "new" stat is stuck open, this could happen.
I don't think the engine temp is key in getting the transmission into
OD. I think it's more reliant upon the transmission fluid temp. I
could be wrong tho.
