A family member has a 2005 Civic with about 135,000 miles on it. Wow !
Live in New England.
The transmission fluid has never been flushed, or replaced.
Before I suggest that this would be a good idea to have done, thought I'd
ask here first.
I seem to remember Posts for different brand autos where it was said,
strongly, in effect, "if it ain't broken dont fix it", and that not to
replace the transmission fluid - just leave it alone as replacing it
would/might cause more problems than having "dirty" trans. fluid.
As to be expected, there were many Posts that said it should "most
definitely" be replaced every XXX miles.
What do you think ? Replace or leave alone ?
If replaced, how often ?
At this mileage, any other fluids or maint. that should be done that we are
aware of; the manual is misplaced ?
