Trans shifting is based on TRANS temp not engine temp. There is a temp
sensor IN the tranny that controls shift patterns. I beleive there are 4
ranges. up to 32*F, 32 to 65 (or so) and over 65 to overheat point, and
overheat and above.

If the trans is below the low limit, or above the high limit, overdrive is
disabled.
