Re: 6 speed transmission fluid change, When?
All due respect BBallr, but nothing is "lifetime". Just like with engine oil, trany fluid has a service life and will break down with use. Since i do my own oil changes when required and document everything to the "t" to keep my 5/100 warranty in "no questions asked mode", I also want to keep the rest of the power train there too. I did find in the owners manual on page 6-6 "Additional Required Services"
* Change automatic transmission fluid (severe service only). Change filter (except 6-speed). See footnote (h).
* (h) Change automatic transmission fluid and filter
(except 6-speed) if the vehicle is mainly driven under
one or more of these conditions:
− In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
− In hilly or mountainous terrain.
− When doing frequent trailer towing.
− Uses such as found in taxi, police, or delivery
Don't you think this is a little open ended?
Doesn't performed and documented service to the power train reflect an "under warranty covered repair" if it becomes necessary?
