Maybe someone who is knowledgeable can answer this, why did MB switched from A0039937296 (2397MM) belt before chassis R102607 to A0039937396 (2390MM) after R102607, as i can see they both for same automatic transmission so i'm wondering what is the reason, i am currently driving on post R105607 even though my car is before that chassis because that what the rmeuropean site said i need. I digged a little deeper and found this discrepancies. Anybody have suggestions? lol Im suspecting its around time they went from 7G to 7G+ transmissions..?
