I'm guessing 2 things from the video: 1) It relates mostly to manual transaxles (very few automatics in Japan); and 2) Sell more Genuine OEM Honda Transmission Fluid. V! Good link, tho...

The purpose is to get the ratio of synth to regular as high as possible, since only about a 1/2 is drained with the plug method.

The proper way is to disconnect the lines from the radiator, identify the output and input lines, place the intake line in the bottle of fluid and the drain line into a disposal container. Then, have an assistant start the vehicle while you monitor the flushing process. When the output looks satisfactory, shut off the car and clamp the lines and re-install.

I didn't really have anyone around that weekend to help out and the plug came off pretty simply.

That's the reason for the quick-change interval. I'll also be able to inspect the magnetic plug to gauge any metallic wear issues.

Yes, it looks like he's talking about manual transmissions. He explained that the tranny fluid stays there, like a bath. True for std tranny, not true for auto. Auto tranny fluid gets cycled through the cool side of the radiator. Doesn't get filtered but it does get cooled.

I usually rely on videos for DIY solutions and I found this one about transmission fluid replacement. Can I rely on this video and does it show the complete procedure?

Thanks in advance. I really need an expert’s guidance..
Hi Chuck-

#1: Disclaimer -- I'm not an Expert on the Subject

#2: The video looks to have been removed from You Tube by the user.

It depends on the vehicle you have. The transaxles that I generally work with have a drain plug, which is the simplest way to drain ~1/3 of the fluid using a one-man operation with fewer labor hours (Honda/Acura models) -- on the flip-side, the entire "old" fluid supply is not purged.

I essentially performed 2 drains and refills with Synth on the Integra last year. UPDATE: It exhibits flawless operation (solid shifts, no shudder, good temperature figures, and excellent actuation on the TC). Still today, at 150K+ original miles, it operates perfectly with the inclusion of a manual torque converter switch. Plus -- a gallon of ATF is down to $50/gallon, so it's an even better deal for preventative maintenance!

I am about to drain our '06 TSX's fluid, which has over 65K miles, and replace with synth, during the next 2 oil-change intervals, since we plan to keep the car a LONG time. The auto-trans seems to be an area of special attention for these models. So, the process to purge the system of nearly all existing fluid is pretty complicated, and helps to have 2 people to assist.

Next week, I will be working with a teacher/mechanic and his students at the nearby high school, to replace a timing belt on an '05 Civic. It's a great place to learn and help other learn the trade of Auto Shop. I have a list of questions to bring-up during off-times, including this very topic

Perhaps more on that later...

Happy EcoDriving,
RH77
