<<However, I'm pretty sure my transmission starts in 1st gear, not 2nd. >>
I just looked it up.\ It does and it is the same tranny [ 722.369]
as the later E320 . They are actually the same chassis # also.
However , the shift delay is supposed to be 2-3, so you may want to check that....
On the 2nd gear start, one thinks the delay is 1-2, but in reality it is still 2-3.
