Just got back from a little weekend outing with the fam. We took TL instead of our van as I wanted the TL to take a long trip. We probably logged about 700 miles. The car was smoooov and comfortable but the transmission was not consistent in its shift pattern sometimes it was smooth but sometimes it shifted hard and jerky. Are there any service bulletins on the transmissions??

 

I think the trans mission was trying to learn the way you drive. I get that sometimes when I go from constant hard accelerations to high way cruising.
