Hi. My english is not so good so i will go straight to the question. Witch oil goes to gear box (transmision shifter 1-2-3-4-5-6 ) If you know what i mean. Greetings and thank you for answer.

Hi
Not sure where you get the 6? speeds from as the 2005 Ducato 244 2.8JTD only had 5 speed gearboxes fitted.
It is good idea to use the original oil as replacement - Tutela SAE 75W-85 APIGL4.
Cheers
