Berlina auto trans oil stick

[mickl]

Hello again,
I just pulled the bonnet up to find the top off my transmission oil dip stick missing.......who knows how it broke off!
Now, I can maybe add a new piece to the top of the old dipstick but knowing how much of it sits in the tube to accurately show fluid levels will be the trick.
Can anyone out there with a 2litre auto measure up all dimensions of their dipstick....such as "bottom to cap" and let me know please.
Thanks
Mickl
