im 16 and i have a 99 acura tl that my dad gave me i think there is something wrong with the transmission but my dad thinks otherwise.when im just cruising it feels sometimes like it in too high of a gear and takes a long time to get up to speed. if i floor it, it sound wierd when it shift like it revs up super high. heres a vid i put on youtube of it. do i need a new tranny or just fluid?
