The 6HP26/6HP28 is also found on the E65 7-series and E70 X5 4.8i's. The 6HP28 is a very nice transmission, with a good overall step ratio of 6.04 (between 4.17:1 1st gear to 0.69:1 6th gear).
335i has always had a variant of the 6HP19: The 6HP21 |
how sure of you of this info? Mine is build date of 10/20/2009 so i guess i got the 6HP28 which is good to know!
