Honda techs just add 4 quarts, run through the gears then drain off excess at the check bolt.

i have some sugggestions for next time .. replacing washers is a must, and torquin the bolts are a must..

Instead of removing the check bolt to check the fluid level, can I just measure the exact amount of oil taken out and putting back that same amount of the new transmission fluid? Because my Honda Accord 2017 hybrid doesn't have the exact check bolt location as yours, and it seems to be very difficult to find out where it is.

Hate CVTs though 😂. The Nissan Primera M6 hyper was a good one when it was new to be honest.

Also on a side note a mechanic told me theres a transmission filter inside the transmission pan that needs to be replaced also did you know about this? does this also have to be changed i havnt seen anyone change this out also and alot of newer vehicles have it i think.

Would it be possible to fill the transmission through the level check plug with clear tubing and a quart pump?

Didn’t see u change transmission filter

How often?

Do you check it with fluid cold or hot engine off or running

If its the first drain ? I just let the fluid drain, weigh what comes out and replace with new fluid that weighs the same. Or you could measure what comes out just add that amount.
