Guys, please read the thread. I feel like I'm repeating myself quite a bit here.
The transmission coolant loop will be thermostatically controlled. It won't open until the engine coolant is at some set point to avoid prolonged fast idle / fuel enrichment mode. Therefore, it will have zero effect on warm up times. Also, the engine block is going to be insulated to decrease warm up times and provide heat to the new coolant circuit faster. If that isn't enough, I will also be looking into using exhaust heat to further speed up the warm up process.
I will be using a modified transmission in the car. I'm not willing to test out lower viscosity fluids due to the risk of damaging or reducing the life of the modified transmission. Therefore, I see heating the oil as the only reliable method.
