    Question Two questions about tap shift mods...

    I have to 2.0T AWD ATS in Standard Trim with all the options available except the sunroof. In this trim you do not get paddle shifters unfortunately, which I thought to myself, "meh..probably a novelty. I'm ok with the center stick control" However, being that my previous car was a BMW 328xi, the "tap shift" on that car was pull back for upshift, push forward for downshift. The ATS (and most other cars actually) it's the reverse, which has led my to see the "shift denied" screen on the DIC more than a few times.

    I was thinking of two mods, and wondering if anyone knows whether they are possible.

    1) Add aftermarket paddle shifters. I have to believe the harness is still in the steering wheel assembly somewhere, right?

    2) Reverse the wires on the tap shift control so I get the racing-standard/BMW implementation of tap shift.

    Any gurus out there with thoughts? Any vendors with plans?

    Re: Two questions about tap shift mods...

    I have both the paddle and center gear tap shift on my car. I just came from a manual gear shift car and I use the tap shift most of the time. The paddle shifters can be a PITA especially when turning. Only nice for the race track but not practical in real life. I think pushing forward for upshift and back for downshift is more intuitive. I would not worry about adding paddle shifters and just get used to the tap shifter the way it is.

    Sounds like a mental reversal could fix this - just try to get used to it?

    Doubtful - the two car models (Standard/Luxury and Performance/Premium) differ a lot and I would be surprised if they were not optimized for parts and mfg.

    Sounds doable

    The big negative of the tap-shift is tha,t once you select a lower gear, the car will not up-shift past that gear. The problem comes when you slow down - each gear that drops becomes your new 'max' gear, and eventually you'll end up in M1. Meaning that you now effectively drive in manual gear selection mode. For manual up-shifts, I would prefer the BMW reversed approach, but only for aggressive driving. In reality, I find that I switch back to A mode, for up-shifts, and use throttle control instead - in S mode.

    Well, intuitive as far as mindset maybe, but not racing common sense. When accelerating it pushes you back, that's why it should be back for up shifting. Same for down shifting. You should be coming up to a corner and braking, therefore downshifting is forward.

    Exactly. If you've ever driven a sequential gearbox (sounds like you may have also) this is exactly how it works and it makes sense. The reverse (and more common) tap shift pattern just feels odd.

    Agreed. It's how it should be in my mind...

    ...and why I love my manuals...
