Tranny fluid Change

[Edgeman]

what he said ^^^^ amsoils amazing stuff. night and day difference from conventional oils. i went a full 10,000 miles last oil change and the oil was just barely starting to darken. just remember you MUST use gl4 NOT gl5 in your transmission

You can also do it the factory way if you have a small hand pump. Basically pump fluid into the fill port (on the side of the transmission) until it starts pouring back out, then screw the plug back into place. That keeps you from having to pull your shifter and risking the chance of dripping oil onto your truck's interior.
