Hello I have a question. I 've got a E24(6 series) transmission but I don't know if it's a 4-speed or 5-speed gearbox. But I've got the numbers that are on the gearbox. 262.0.200.00A or 262.0.200.0017 the last number wasn't easy to read. And I've got what I think is the order(VIN) number from this gearbox 04263279 Does any body know by this numbers what kind of box this is 4 or 5 speed.
