Hi Gilly,
for the tranny, i still feel very solid, the car itself has 38000 miles. anyway will bring the car to do the ppc next mon, b4 will change the atf first.

for the parktronic, some said there is a tiny battery in every sensor, if those battery fail to work, the parktronic wont woke..... some said maybe fuse problem, anyway it is not a costly repair
