How can I tell what Auto Tranny I have?

I'm in the process of buying an 2008 E93 with the auto tranny. It has the paddle shifters. How can I tell if it's the sport transmission. And do I need it?

My intention is to fix all the maintenance issues first and then do FBO's. It does have an oil cooler and the sport suspension package.

All of the automatic 335s have the same zf 6-speed transmission. Only 335s built after 03/07 can be flashed with the Alpina flash.

Does the Alpina flash just change the shift points. What's value in the Alpina flash for FBO Auto? Thanks.

The alpina flash raises line pressure, so it can hold more power without slipping. The paddles are more responsive, and the cluster shows gear number in D/S/M. Shift points are more aggressive in S too.
The downside is really low shift points in D.

Everybody raves about the 7601494 flash, but don't use that one. It's for an N52, so it won't hold N54 power.
