I fought with this same issue for a while. I looked all over this forum for fixes and tips, and other sites as well. I kept seeing "check the warranty" and most of all "change to motul fluid", or "cold shifting is hard" but the one thing I found to work and I wish I could find the thread again to post here, it's all about learning how to drive the car. There is nothing wrong with the tranny. Fluid won't change anything much. And I know it will be hard for us "car guys" to swallow our pride and say we know how to drive, but seriously it's how you drive the car. I have had mine for a few months now and when I first got it I thought the same thing as everyone else on this thread and many others. But then I put sometime into learning the car and I found how to love it and drive it smoothly.
Here are some tips if you wish to try them.
1. let the car warm up when you get in. Wait till you here the revs drop and the oil and fluids kick in. Takes about a minute.
2. Drive a 1/4 mile or so down your street in first gear to get the fluid moving around and tranny warmed and ready to move.
3. Take first up to 4000-4500rpm before shifting into second every time. It's a high revving engine designed to be drifting or on the track at high revs.
4. Always shift every gear between 3500-4500rpms for a smoother shift.
5. Never down shift this car into first unless completely stopped, and never into second unless under 10-15mph while street driving. On track down shift when needed at higher revs to keep power up.
I know it sounds silly but this car is built like a racecar, and racecars do not drive like all your other street cars. Hopefully you get your car figured out and love it as much as I love mine, and no one buys a Camaro instead...
