I found this retrofit in the US E60 forums. Couldn't resist the poison and took the plunge and ordered in the parts.
Before:
After:
The Sports Auto Transmission (SAT) is standard in the 525 last year (I don't know if the current 525 still gets this) and was not available in my 523.
Besides changing the gear stick, the ECU or gear selection switch (the whole base of the gear shift) was changed as well. There is also an additional "SPORT" button. If you turn on the SPORT button, the steering is stiffen up, and the gear takes longer or higher rev to change up.
What I like about this mod:
- asthetics and ergonomics of the new gear knob
- heavier steering with more feel when the SPORT button is on
- gear drags longer before changing up (more than DS mode) without the need to floor the pedal
- almost instantaneous gear change when you're in manual. There is a lag effect in the standard auto transmission when you're in manual.
Overall, I love the mod very much, and no regrets on the money and efforts spent.
Also, change my standard steering to the SMG sports steering at the same time:
Standard steering:
SMG Sports Steering:
And finally a picture of the demodded parts:
Also, many thanks to Ah Wee and the BVO boys for fixing up all these for me! Great job!
Do let me know if anyone is interested in this and need any more info or help.
Cheers!
(PS. Apologies for the bad quality pics taken with my phone!)
