I have a 2002 Honda Accord 4 Speed Automatic and it is due for a transmission flush I have heard mixed reviews that Honda ATF could actually harm these already fragile transmissions. So my question is should I buy Honda ATF or Synthetic fluid. Thank You
I would advise against a transmission flush - Honda actually advises against it as well. As you said, the transmissions are fragile and a flush involves too much pressure. Typical Honda procedure would be to do three fluid drain and fills, with a good bit of driving in between each change. If the fluid comes out red and clean, without metal shavings, you don't need to do all three - be your own judge. I've recently done my ATF change on my 2007 Accord, making the switch to synthetic ATF fluid (Redline ATF to be exact, it's highly reviewed for Honda transmissions). My fluid looked pretty good at the first drain, so I only did it twice. Shifts definitely felt a lot smoother after. Overall, I think it's more personal preference for fluid - but there's no harm in using synthetic. I personally sway more towards synthetic.
Underground mineral deposits can be located by drilling boreholes and analyzing the core samples.
