Re: cold temperature gauge

Sure enough, it was the thermostat. Pulled the old one out and the center part was warped or bent such that it couldn't close completely. It was also marked 76°C (170°F), lower than OEM. Guess the last owner thought that a lower temp would be better...uh, not quite.

With the new t-stat, engine runs at one temp after warm up and the TC functions normally.

[UPDATE] I swapped the OEM temp with a new 170°F thermostat. Engine runs a bit cooler now but still plenty high enough to allow TC lockup.
