Switched from Honda Z-1 to DW-1 trans fluid. Noticeable shift quality change.

I just did a 3x3 drain and fill using Honda's new DW-1 auto transmission fluid on my 07 V6 auto. Boy huge difference for my car. The shift is much firmer without that gliding over smooth shift feeling. The gears engage milliseconds faster compare to before. Going from R to D or D to R is quicker with perhaps a half second shaved off. I used to have to hold the brake until I know the gear was in before I started moving. I think this will solve a lot of auto transmission issues.

When I did my DW1 change, wow. I typed the same review as you. 2-3 months later now, the AT feels kind of the same as before, as I remembered it.

I no longer think it's the miracle ATF. It's good. It's Honda ATF. So it's what I will (continue) to use.

Honda ATF is BAD... OP, if you noticed that much of a difference with DW-1, you should switch to Redline Racing/Lightweight Racing Type F synthetic. I have it in my 06 AV6 and it has completely changed the attitude of the car. I have a couple threads here that I've made about it. DW-1 still has friction modifiers which make the clutches/internal parts wear... Type-F fluid has no friction modifiers so (in basic terms) it makes for instant shifts without lag, and in turn, wears the internals much less. So your DW-1 may help if it has less friction modifiers, but the Redline Racing/Lightweight Racing will help much more... Big difference

I think that the Dw1 is a better fluid but I certainly think Redline D4 is better than Dw1.

When you get to 200k miles, let me know by then whether you are still living large on that no FM Redline fluid.

Let me make a point here. Redline recommends D4 in our cars not the others. I would personally only run D4.

On what grounds do you think DW1 is better than the Type F, but D4 is better than Dw1? Makes no sense because Type F is better for your car than D4.

Your point is moot because while they recommend D4 for our cars, they CANNOT recommend a Type F for our cars for liability reasons simply because its named "racing fluid". Doesn't mean anything in the way of reliability, all you have to do is read up on what friction modifiers do to a transmission.

You all should really read this thread

I was ON this thread. But unless you can prove the long term reliability to me, I can't use that fluid. I ran Z1 on my old 98 V6 transmission for 200k miles. Granted that I had second gear slippage problems by the time I sold the car (probably due to age), but I got there without a transmission rebuild and avoided all major transmission work.

And on what grounds can you say that type F is safe?! Don't stick your foot in your own mouth by saying on what grounds can you say DW1 is better than F?

On what grounds can I say Type F is safe? You say you were in that thread... Did you actually READ that thread? Its simple in theory and any reasonable person can comprehend it. I'm not going to go through the significance of FM vs. Non-FM again.

I in no way shape or form put my foot in my mouth. It's 100% common sense... But I guess common sense isn't so common.

I could care less what you use really. I tried, but if you want to believe in Honda that much, go ahead.

This is the same thing I'm waiting on hearing about.
