You might find they have a different bell housing. Gearbox part numbers relate to the box only, nothing bolted to it to allow it to fit a particular model of car. For that you need the manufacturers part numbers to match up.sunnydays wrote: ↑Mon Dec 04, 2017 11:48 pm I guess the real question is could you just take the dct out of say a 335i which also has the n54 and drop it in the z4. Its the same model dct and engine etc.... and these boxes are only around £1000 when they appear on ebay. This is certainly more reassuring if it can be done!
If you are worried about the cost of repairs you need to either relax and accept it is inevitable that the car will cost you money and enjoy the car, buy a warranty, or buy a ford!!!!
