Common issue.
Solution for me was a new transmission under CPO warranty.
What's happening is the transmission is trying to start out in 2nd gear (fuel mileage), but you ask for brisker acceleration so it downshifts to first. Hard. Mine got so bad it felt like I was being rear ended by a truck. Neck snapping bad.
If you aren't lucky enough to have a warranty on the vehicle, I suggest a simple fluid change (assuming you have less than 70-80k miles). I get my fluids from
The California Transmission Supply Company, but I'm not sure if they ship to Canada. Get the Lifetime 6 fluid and, while you are in there, an extra fill plug in case yours is buggered up like mine was (on the rebuilt transmission, no less).
Of course, you could always come to a full and complete stop, then the problem doesn't occur!
