[Shotimes] Strange ATX behavior

[John Weidenbenner]

Mike,

Another factor affecting the warm up time is the thermostatic control in the
trans cooler line. It is supposed to bypass the air to oil trans heat
exchanger to speed trans warm up. Suggest to the dealer that it may be stuck
open. Your warm up time is really long for 70 F, so a stuck open control by
itself would not cause the long cold no lock-up condition.

This may have already been discussed, but is the engine thermostat working
properly?
