Hey guys. First off transmissions aren't really my thing, so i thought I would post this up to ask you all. I am getting some odd shifts, kinda like the transmission is dropping into gear, almost like hard shifting, but I am unsure. Also i was wondering if I should change my fluid and filter and what method I should use or if it is even applicable (117,000 miles). Like I said I don't know a lot about transmissions so any help would be great.
