What are some of the 2010 Volvo XC60 transmission problems?

Owners of the Volvo XC60 complain of transmission problems that include hard shifting between 1st and 2nd gears and slow movement when reversing. Engaging drive when backing out can take several seconds and drivers hear "clunking" and experience hesitation. Downshifting produces stuttering and rough reactions at low speeds almost 99 percent of the time. Failures and awkward gear movement appears at less than 70,000 miles and as early as 20,000 miles. Some incidents indicate low transmission fluid, but all occur before recommended service intervals for the XC60's transmission. Cost of replacing the Volvo's tranny begins at $3,500 and having the fluid flushed and filter changed averages $150 in materials and labor.
