i need to drain engine oil and i will replacement my jatco gearbox soon, before i buy oil i read RAVE manual and i found
Engine - KV6 (including oil cooler and filter):
⇒ Refill 5.2 litres (9.125 imp. pts)
⇒ Fill from dry 6.0 litres (10.625 imp. pts)

Automatic gearbox - JATCO:
⇒ Refill 4.0 litres (7 imp. pts)
⇒ From dry† 8.5 litres (15 imp. pts)

which number must following refill or from dry?
NOTE:
for my engine i will make drain, and my gearbox i will replacement all gearbox with new one

Refill are for warming up and testing purpose. The Dry are technical reading from the factory. All oils expand under temp and this is where leaks from seals can be found. After the testing topping should be to the required markings. Hope this helps.

I am correct?

Your engine is just a simple change or refill so you'll need just over 5 litres.
The gearbox quantity required is dependent on weather the torque converter is empty or full. If the reconditioned gearbox is being supplied with a new torque converter, then it's likely to be empty, so needs the dry fluid quantity fill it. If you are using your old torque converter, you'll only need to fill the gearbox, so you'll need the refill fluid quantity.
