2005 Honda pilot, transmission slips after half hour driving.

What is your question?

The transmission slippage problem after half hour of driving is consistent. the car use to overheat so I change the thermostat, it leak coolant through the radiator so I change the radiator. Now no leak and no overheat, just after half hour of driving the engine will still run, but the transmission has no gears. After a few hours with the motor turned off, the vehicle runs great again (for half hour).

How long has your 2005 Honda Pilot had this problem?

About a year now.
