i have a 2001 Volvo s80 t6 with about 222,000 miles on it, it has run fine up until now, however yesterday it started shifting hard literary jerking me in my seat every time it shifted. after about 3 miles it shifted fine. today i went in my car and drove to work and the car was stuck in third (3rd) gear. switching to geartronic didn't change the gears. also i have a Transition service urgent message on my dash. any help would be appreciated
