Hey guys, I want to flush out all the old transmission fluid and replace it with new stuff. I know you can take out the plug but it only drains like 4 quarts and the total capacity is around 7.5 quarts. Would it be ok to unhook the lines leading to the cooler, sending line into a drain pan, and return line in a jug of AT fluid? I dont know if there needs to be pressure on the return line for it to suck up the new AT fluid. That or pour AT fluid in while it comes out the bottom.

 

When is the last time its been changed? Typically there is no need to drain more then 3 quarts from the pan per the service manual. (3 quarts is all that comes out) If you wanted to drain a little more you could get it hot and then open it up but i wouldnt recommend it. As long as you change it on the regular interval theres no reason to do a complete flush.

 

Its been a while, I replaced 4 quarts last year. But I would feel better knowing that all the old stuff is gone, I dont see the point of going to a shop to pay for a flush when I can do it myself. Prior to me replacing the 4 quarts I dont know how long it went with out a change, I put about 20k miles on the car since I got it and im at 167,600 miles, a flush sounds good for it.

 

your fine with just draining and refilling, trust me, i do mine once a year with royal purple max atf

 

You think it would be ok to mix the Royal Purple ATF with a different brand? Last time I think I used Valvoline.

 

quite alright alot of people are gona advise against the use of the RP, but i have had no issues and my car is supercharged, and i race it.

 

True, OEM Honda/Acura fluid is what people will say, I wonder how much the dealer wants. If it costs more then ill probably just go for royal purple.

 

same price usually, dealer wanted 12.99 for the Honda ATF and i think the RP at advance was 13.99, i liked the qualitys of the RP better and i like the way the trans feels with it.

 

Are Dexron II, III, and VI different? I believe the ATF I need is OEM/Dexron II.

 

No need to worry about getting all of the old fluid out of the system. Just do a drain & fill.

Use the new Honda ATF DW-1, part number 08200-9008. It's a new synthetic formula just released in the past few months and costs a little less than $8/quart from the dealer (if they try to charge you more, they're marking parts up above Honda list price - go to a different dealer). Shift quality is noticeably smoother than Dexron II/III, and is better than the old non-synthetic Honda ATF-Z1 in cold temperatures.

 

yes, your transmission was made for Honda Z1 fluid, since the RP is a completely independent ATF fluid it is compatible for almost anything except CVT's

lol my trans hates the cold with the RP, it has a much higher viscosity rating then your standard valvoline ATF
