Have issue on my 2013 V6 automatic that's driving me nuts. Car has ~38000 miles, noticed it in last year or so.
Hard 1-2 shift in stop and go traffic. Feels like you've been rear-ended... happens as car shifts from 1-2 at ~1500 RPM at 10 MPH in slowly restarting interstate traffic, or rolling around a parking lot (slowly.)
Less noticable in normal stop and go where the 1-2 shift is happening at higher RPMs / higher torque and there's a better launch, but you can still feel it... it's a very positive shift.
Anyone else have this issue? What are the fixes? This is the kind of non-specific stuff I hate to drag car to mechanic over.

with transmissions being serviced either under GM's factory warranty or certain cheap aftermarket warranties), all of which would have wildly different total costs involved.
