Anyone do a drain and fill using 3.5 quarts of RP and mixing it with your OEM fluid? I'm thinking of doing that. Thanks in advance.

I dont get the point, I understand from multiple posts that RedLine is the best switch with acura ATF; sorry for assuming yours is auto, but if it isn't I would highly suggest RedLine. Anyway, wait for C25 to reply to this thread and I am sure he will give you a solid answer.

The only other suggestion I got is to go with GM TF, it's a little more specific than that but if you look it up you could identify the correct one, which is actually superior for our transmissions.

Please reply with your position/opinion. =)

The Optimal Percentage of Racing ATF - AcuraZine Community

Happy reading.

I would NOT mix the OEM DW1 or Z1 with anything.

I've just stuck with the OEM Honda Fluid. I've sold some Torco HiVis ATF to some customers before and they've reported good success, however I'm still a little hesitant to use the ATF in the truck. I've done a switchover to DW1 and thus far, feels much better than Z1.

This would no way, even with the info on the link, damage the seals on the trans? Reason this question comes up because I think you guys are going for optimal performance under hard driving conditions, not what is the best overall for your trans.

No, it won't cause damage to seals.

Almost EVERYONE (who follows up on Acurazine) swaps out the Z1 fluid to the Type-F mix in the link provided.

You don't have to "drive your car hard" for it to be beneficial.
Ironically, Z1 is the worst fluid.
People swap it out to prolong the life of the transmission.
Quicker, snappier shifts = less wear on the transmission.

It's EVERYWHERE on Acurazine. Do research.

It's really tiring to repeat why go to Type-F.

Redline Racing Fluid http://www.redlineoil.com/product.aspx?pid=52&pcid=9
This is the fluid you linked to in your post above. When people on this board refer to "Redline fluid" or "Racing fluid" or "Type-F" they are usually referring to this fluid. This is a high quality synthetic fluid and more importantly, it does not include any friction modifiers (FM). Some of the experts on this board discovered that FM causes wear on the transmission clutches and this wear can be seen as metalic material on the magnetic drain plug. Acura's OEM fluid, Honda ATF-Z1, includes a ton of FM. All of this FM intentionally causes the clutches to slip for passenger comfort, but this results in transmission wear. Members have shared their experience and usually note that there isn't much of a difference in comfort so there really isn't any downside to this.

Redline Lightweight Racing Fluid http://www.redlineoil.com/product.aspx?pid=137&pcid=9
This is identical to the above fluid, but with a lower viscosity so it is a thinner formula. The Racing Fluid has a higher viscosity than the OEM Honda ATF-Z1 fluid while the Lightweight Racing Fluid has a lower viscosity than ATF-Z1, so some members (myself included), especially those in colder climates, have chosen to blend the Racing Fluid and the Lightweight Racing Fluid to end up with a viscosity that is more similar to the OEM fluid.

Redline D4 http://www.redlineoil.com/product.aspx?pid=51&pcid=9
Redline's D4 fluid is designed to be a replacement for Honda's ATF-Z1 fluid and includes friction modifiers (FM) just like the Z1 does. Many on this board feel that this D4 fluid is significantly better than the OEM fluid, but the general feeling is that the Racing Fluid or Lightweight Racing Fluid (or a blend) are better for the transmission and result in less clutch wear since they do not have any FM.

I am not an expert on this matter, but am summarizing the information that I have learned by reading posts on this board for the past couple years. I hope this helps.

I think that most of the transmission experts are tired of posting the same comments on trans fluid. All the answers can be found in a couple of very long threads if you search.

In fact, if you make a thread about it on Acurazine, you'll likely get flamed for not searching and end up getting it locked.

dope man good looking, that is what I got from the stealership service advisor supervisor, and not that I trust them but I do not understand why they tell me if you use anything outside of factory fluid the seals will get eaten and the trans will leak; only ATF. Is there anything that will actually do such a thing? or just hot air?

They know me already, cause I do buy all my fluids from them and they know I do not service my vehicle with them regardless since I purchased the vehicle; I just use a discount I get from them which pretty makes everything dirt cheap

You'll be fine, buddy.

Most Type-F fluid is fully compatible with our transmission and the seals.

The only real difference between Redline Type-F ATF and the OEM stuff is the FM (friction modifier).

Redline racing or any other type F like Amsoil Super Shift for everyone from a grandma to a pure track car. It's marketed as a racing fluid now but at one time it was an OEM fluid. Just marketing, that's all.

Less FM equals quicker shifts, more holding power, and much less wear. Because the shifts are quicker and the bump shift is eliminated shifts actually feel better yet it's shifting quicker and harder. It's the best of all worlds. No need for D4 or any other non type f fluid and no worries about mixing with Z1 or how quickly you do all 3 of the drains and fills. You car will shift better than stock and you will nearly eliminate trans wear. This fluid along with the switches will nearly eliminate trans failures.

Plus, Hondas have great seals.

If you DO want to stay OEM, go with the DW1 ATF.

Honda has replaced the Z1 with DW1, and it's actually a lot better than Z1, but it's still no Type-F.

Cheers!

Thanks for taking the time to clear it up, I definitely understand the situation a lot better now and know what choices to go with. I have 3 honda's, and my of course my Precious =)
