10R80 - no drive when cold

Had an issue pulling 2.5tvan from cold start up a small grade. Low range 1st. Lost 90% of drive. Also got vibration.

Once up no drama. Steeper slopes that day were fine.

I suspect the fluid drained a bit overnight with the slope.

Is there a PID/s I can monitor for fluid pressure that would tell me I’m good to go? If so does anyone know what a
The acceptable pressure would be?

Or does anyone have a hack to get the pressure up when cold? Manually cycling the gears?

Hi.
If I leave my car in the shed for several days I have to let it idle for 30secs or there about to allow the torque converter to fill with fluid.
Overnight it never drains.
From memory some PX3 models had a recall with a faulty transmission pump, maybe ask a dealer, it may also need a TCM update

That would be this recall - https://www.carexpert.com.au/car-news/2 ... t-recalled
List VINs recalled isn't coming up any more.
