Rough 3->4 shift when cold?

[BlaydeX15]

Just wanted to mention this here and see if anyone else is seeing a similar issue. The last week has been cold (High of 35f), and on my way out of the work parking lot, I'll hit ~30mph, and then the 3-4 shift happens and it kicks pretty hard (Like: First time stick driver missing a shift). About 3 miles down the road, I do the same 30mph 3-4 shift, and it runs just fine, so it's just the first ~30 seconds of driving where the shift is rough like that.

I know that everything in the drivetrain is rougher than normal when the car is super cold, but this just seems to be a bit excessive. Any thoughts?

I had the same issue you're reporting. I recently had recall work done (Issue Number SA341 - Fast Static Gear Shift Logic Improvement) and the problem seems to be solved.
