Hello

The car is a Fiat ducato 2.8jtd (i think) from the start of 2002.

I got inspired from some treads on this forum, and desided to change the speed sensor on the gearbox (speedo doesent work).
I took the sensor to a dealer and got him to by a new one to me. But when i got home and i put the old sensor in again, i dropped the long plastic thing with a cogwheel on the end, in the gearbox :bang::bang:

So my question is, can i get it out of the oil draining plug, or do i have to remove the gearbox to get it?

Another question, i have some 80w-90 oil, can i use that to refill the gearbox afterwards, and how much oil do i have to put in the gearbox? (doesent have the manual to the car

The picture are the sensor, in the left side you can see a bit of the plastic thing.
Greetings Henrik
(sorry for the bad english)

2.7 litres , google for the correct oil , that isn't it ; I think it is 75/80 fully synthetic , in for life ....personally I use semi synthetic and change every 40,000Km
