Steptronic vs MT for the ZHP

^clear the transmission adaptations in addition to the maintenance.

Maybe this is for another thread, but how hard and how much is it to put paddle shifters on a step?

It is rather simple.

Used SMG wheel - $200-250
New clockspring - $110
Wiring piece and connectors so it is OEM and reversible - ~$34

The DIY is pretty straightforward and the total cost is roughly $344-394. You can of course source the parts used if you find someone parting out.

The paddle shift mod is surprisingly easy, especially if you can buy an already made harness... then it's plug and play. You have to get an M3 SMG clock spring, and M3 SMG steering wheel with the paddles (I changed my paddles out), and the wiring harness (that you can make). See the DIY posted. Happy to provide more detailed input if necessary.

How do you clear the Trans adaptations? My tranny occasionally holds the gear on hard acceleration and won't shift until I let off the gas.

Via software, but I don't know the specifics.

On our X5 the adaptation can be reset...

Key in position 2
Fully depress the gas pedal
Hold for 25 seconds
Start car

Can't hurt to try it on an E46

Cool, worth a try. So after you hold the pedal for 25 seconds do you let off before starting?

I do but not sure if it matters. On the X5 the difference is pretty substantial after getting stuck in traffic and being forced to drive it slow.

BMW automatics have come a long way in the last few years. The 7/8spd units in the newest cars are pretty amazing. No way a ZHP auto will function like the newer units.

I prefer manual trans for control and speed of gear changes. The new BMW autos change gears amazingly fast. But they still don't give you total control. I'm not sure if that can or can not be fixed through software.
