You have got me thinking now Richard. The gearbox pump is powered from the input shaft and, when the engine cut out yesterday, I kept it in D the whole time, so the gearbox would continue to have the input and output shafts connected because the pump would continue to run and the torque converter would still be spinning.
If I had taken it out of D and put it in N while coasting down the hill, there would be no drive through to the engine. The engine would stop turning and the gearbox input shaft would stop. The torque converter and gearbox pump would also stop. Putting it back into D would have no effect. I would have no drive.
It is a chicken and egg situation. The engine needs to be turning over to take up the drive. That is why tow starting won't work.
Am I making sense? Anyone disagree?
