Are there real differences in the auto-trans used in the 550i vs the 535 (2009-2010)? If so, what are they. I have an 08 530 and the at sucks, imho.
Thanks for any input.

SAT or regular....
SAT
Not at all pleased with the shift response (delay) with the 530 box. Assume the 535 is similar.

Just do a test drive and find out.

It appears the 535i can be had with the same Sport Auto with paddles as the 550i. I can tell you there is no delay with the 550i SAT upshifts or downshifts with both sport modes set (shifter and console button). Its MUCH more responsive than the older steptronic.

I thought I read here that BMW improved the auto transmission's shift times in the LCI trans but I will defer to those here more technically saavy than I am on that.

My LCI Steptronic is incredibly fast with its shifts in manual mode. The Step and the SAT share the same internals.

The "sport" button on the SAT shifter greatly improves the already fast shifts..

I thought I read somewheare that the V-8 units had a different transmission than the L-6. Maybe I was thinking of the M5. Anyway, the Step works fine in normal traffic and flat road, but when I put my foot on the floor, I don't want 3 seconds of delay!
