i was wondering if you guys can give me some tips on maintence for my transmission 04 tl Automatic , if i drive the car hard sometimes it wil make a crack or jerk when im coming to a complete stop or say im coming to a complete stop at a red light and the light turns green and i accelerate like if it was in neutral , -- i figured out that if im slowing down i either have to come to a complete stop or i cant let the car go under 5 mph so i have a problem 1 and 2 gear also if im on a long road trip say i get off on an exit ramp when im slowing down it will down shift hard by itself from 5-4 but thats rare

 

Change fluid, change switches, and search. Transmission maintenance tips are very well covered within the forums.
