Hi guys I have owned my TL for about 7 months now and I love it. It is probably my favorite car I have owned but what I am worried about now is my transmission. Do the 04's also have trans problems like the older TL's did? My transmission will shift rough only when the car is cold but sometimes it will shift rough even when it is warmed up. Should I be worried or are these transmissions not a problem on these cars?

 

not as bad as they used to be, but could be bad without proper care
change switches, filter and fluid regularly

please search before posting, it's one of the most discussed topics around here

 

Do at least a couple drain and fills with the new DW-1 ATF, makes a noticeable improvement in shift quality.

The transmission issues were apparently fixed during the 2004 year model run. So if you have a later '04 build date you are probably okay.
