Is the new dw1 atf safe to put in a 03 acura tl-s????

Just did a 3x3 over 3 weeks with ATF-DW1 on my 99 TL. Much much smoother than before. Just try and do 1x3 over a week first and then continue with the rest.

once my dealer switches over to dw-1 i will do a 1x3, they still have a stock pile of z1 they need to get rid of. dw-1 is compatible, and contains some synthetics and is a little bit thinner than z1. if all is well, it should be a step up from z1 and give some improvements.

you guys should try redline type f instead.

I agree FirePR, I did a 1x3 today with type f and noticed a considerable difference. I have a slippery 1-2 shift that improved noticeably.

But yes the dw-1 is backwards compatible with the z1. It supposed to be a better fluid.

But with all of the recent posts about redline/amsoil fluids working better in our trannies, its going in in the next change.

Theres tons of threads on this. I would read up on it and make your own conclusion on what you wanna do from there.

just be aware that once you switch to those fluids, you probably not going to be able to go back to honda fluid. my rebuild tranny is still under warranty so i will be sticking to honda fluid for now. also keep us posted on long term usage of these alternative fluids, thats what matters, since any fluid may have a short term fix.

Yes, it's backwards compatible with Z1

Just did a 3x3 a few weeks ago. Cold shifts are considerably smoother. Otherwise, it feels about the same.

FirePR2002

not true - nothing stopping you from changing back. the friction modifiers in Z1 would "re-coat" all the internals pretty quickly once you did. it takes a couple days to fully notice the affects of type f - because it has to "wash" off the z1 modifiers.

gold2003tl (90)

not sure if your directly referring to me, but have used nothing but z1 in my transmission. In theory this "re-coating" of friction modifier would work, but long term effects of using type-f fluid, or diluting z1 with type-f fluid isnt really known for 2g tl, more feed back is needed. I know people over in the 3g tl forms have been playing around with this stuff a lot more, but their trannys are not quite the same as ours. They also have different electronics, like a microsecond throttle blip during shifting. If regular universal atf is used long term, which contain friction modifiers, like amsoil, mobil 1, ect..., the chances of going back to z1 without slipping is slim. many people have played around with that stuff to fix shuddering, and such, but their trannys are long gone by that point, only a temporary fix.

my current plan in to stay on honda fluid until my warranty is up, then slowly introduce some type-f fluid. maybe do a 1x3 with one quart of type-f fuild, redline.

gold2003tl. so you're saying on the next change, you'll run 2 quarts z1 and 1 of the type f fluid?

And with an '02 with 108k miles, last change was at 77k in 2007....would it be viable to run Amsoil/Redline at this point?

What do yall mean by 1x3 and 3x3? Thanks for all the info..

It's just a way to describe how much is being drained/refilled.

AxB

A=How many times to drain/refill.
B=How many quarts to drain/refill.

So, 1x3 is a drain of 3 quarts followed by a fill of 3 quarts.
A 3x3 is doing that 3 quarts drain/fill three times in a row. (With 5 minute drive in between.)

gold2003tl (90)

my next change will probably still be under warranty, so 3 quarts of z1 or dw-1.

Id be a bit concerned about doing a tranny oil change at this point, since it been over 30k miles since the last change. I might do a 1x3 at this point, not sure if id stick with amsoil or redline. What condition is the tranny in, does it slip or shudder?

mestizoracer310

Just got off the phone w/ Tustin Acura and they said the trans was replaced in June of 2006 with 70,192 miles. So I'm hoping it was replaced with the new material in the clutchpacks.....

Anyway, since it was replaced w/ basically a new/remanufactured to new trans, do I go by the initial 60k service or just go by the 30k?

my.daily'tl'

Running whatever fluid you want is your preference. We're just tired of our shit trannies and trying to improve upon an already established basis from many members experiences, trials and errors.
Some people say dont run this ,dont run that which i think is total bs. There's alot of information going on on better than oem fluids that which still doesnt solve the mechanical problem with the trannies it helps improve the operating characteristics of them.
At 31k since your last change, i think its safe to say the fluid might possibly need changing. (i think i remember people on here saying after a rebuild its good to do 30k intervals.) I'm not a trans specialist but I'm reading up alot on this topic from Azine members experiences and just trying to see whats best out there.

Well Since AMSOIL puke out of my Tranny and the Z1 is Aging in terms of Oil Tech, Ill try out the new DW1 in my Next change of course it will need to be a 3x3. Ill post the Results Next Month.

gold2003tl (90)

some people do a 1x3 every 7500, or 15,000. im sticking to 7500 for cheap insurance.

jsirious

I found it very interesting that the new DW-1 was cheaper than the older Z-1 at the dealerships here in Jersey. So cheaper and better for my tranny? Give me a case! ha ha

The trans holds almost 8 quarts of trans fluid. When you drain it 3 to 3.2 usually comes out. I would if your going to change it, just use all 3 of the same type. The new dw1 is supposed to be thinner and better so you can use that and mix it with what you have in it, or go amsoil. The purpose of a 3x3 is to drain as much of the old out to get as much of the new in. I personally on a aging trans would do a 1x3 and drive it a few weeks to slowly introduce the new chemicals/additives then do another, followed by another a few weeks later.

Speaking of fluids, i need to go get some GM Syncromesh FM for my trans today and change it

who is going to test seafoam trans tune before a 3x3????- which says it removes selenoid crud etc
and might be our savior!!
will call their tech guy Jim D this week and ask some questions

my 01 with 40 on rebuilt warranty unit- shudder/wave feeling as it shifts into 2nd, and now a slight thunk into 3rd
