Question about 1999 BMW 328 Series
I have a 1999 BMW 328 I and the Code reader reads: P0740
(Torque Converter Clutch Circuit/Open) . Has anyone ever encounter this code on their BMW and if so what was the extent of repair that was done or had to be done ?
The problem is with the gear oil. To keep ahead of the rest BMW started what they call life time oil for their gear boxes, though that sounds great it doesn't really work in reality, they have now gone back to recommending a gear oil change every 60k miles.
In short you need to change your gear oil and soon, the oil in your gear box is no longer effective and will damage the gear box. You'll need about 5 litres for your car and costs around £15 a litre, expensive stuff!! I had the same problem with my 328i auto, the dealer was clueless and kept quoting the lifetime oil, I changed the oil and the problem has gone and it's so much smoother.
Hope this helps, please don't forget to rate me.
