Nice write-up.

I have an Auto model, and unless the car's up to temperature, the Overdrive is not available.

This is proving to be more of a pain as we start having colder mornings. As I quickly get onto a freeway on my way to work, it's possible to have travelled 40km (25miles) at 100km/hr (60mile/hr) in third gear before I can get the revs to drop back from a noisy, droning, fuel-thirsty 3700RPM as overdrive kicks in. If I get off the freeway for a bit, or pull over for a moment, it can help warm it up quicker.

If the car's already up to temp (and Overdrive engaged) and the temperature drops for whatever reason (cold freeway driving at speed, or I flick on the heater for the first time and flood the cooling system with unheated water from the heater's piping) then the Overdrive will actually switch off should the temp drop too far.

I'm dreading winter.

So, is it:
a) normal
b) a faulty thermostat that doesn't close properly?
c) or perhaps I could do with a few air bubbles caught in the line.
d) well, it's an auto which isn't a true MR2 anyway, so why am I even on this board?

Thanks in advance for any thoughts.
