Hello. Problem as in the subject. Due to defects in the box I am forced to replace it. The box was working with the Z12XE engine. The Allegro offered a F13 CR box which is identical to mine as per vin.
This is the marking on my chest.
And this is the marking from the box sent from the Allegro. There are no F13 markings under the selector. Does the Opel have other markings and how to read them?
