The ZF transmission in the first year 330/325i is first gen, the ZF transmission on the 335i is 2nd gen, slightly upgraded, this is why the TCU flash won't work, it has nothing to do with the motor if you put a 335i transmission in a 330i it would work perfectly, or switched the 335i mechatronics unit inside the transmission into a 330i.

Not that you would want to put a 335i tranny in a 330i, the gearing has been tuned for the 335i's power curve.


TCU = Transmission Control Module, inside the transmission floating in fluid, yes sounds crazy but true.
