The temp on the left side reads cold, the temp of what I think is oil, reads warm.

The temp on the left with the little pictuer of the gear is the transmission temp. The temp gauge on the bottom right is the engine, it should warm up to about 240 degrees and stay there.

Scott367 or smartmoney, do you by any chance have a picture of this black box you're talking about?

It does read warm after 20 mins, but the air is cold. We can't drain it right now with all the stinkin' snow out. DH was thinking of bringing it to work and putting it up on a rack.

The new thing is that it blows, then stops blowing, then blows, then stops. Sounds like a loose wire???
