Is the 2006 Mk 1 BF Falcon still at risk of coolant entering the transmission and visa versa, or has the problem been fixed by Ford? I recently had the transmission in my car serviced and the mechanic recommended I have the cooling system modified at a cost of about $400 to prevent this problem happening. Your advice would be most welcome.
Changes were made in the BFII model and they seem to have fixed the problem. We don't get reports of it happening on these later models, but the changes don't affect your car. If you intend to keep the car for a long period it would be worth making the modification, but the car is now eight years old so you might think it's not needed.
