I already got the Red Line D4 and I'm planing on doing the 3x3 because I don't know when the last time the fluid was changed.

When I do the first (1x3), I know I have to drive for a couple of miles.
The question is, do I have to take the car off the jacks and drive, or can I just have it switch through all the gears in the air?

Thanks.

put it back on the ground and drive through all 5 gears in SS mode including reverse. then just jack it back up and repeat 2x.

I already know that. Question is why, if it is really necessary.

You can do it on a lift, but I would find it much easier just to drive the car:
1. Set the parking brake, and raise the vehicle on a lift.
2. Drain the trans, and refill it with Acura Precision Crafted ATF Z1/DW-1. Refer to the applicable S/M or to ISIS
for details.
3. Start the engine, shift into Drive, and release the parking brake.
4. Push down on the accelerator pedal to raise the vehicle speed to 2,500 rpm.
• If the trans shifts past 2nd gear, go to step 5.
• If the trans won’t shift past 2nd gear, keep the engine speed at 2,500 rpm and shift from Drive to
Neutral and back to Drive. Then go to step 5.
5. Make sure that the trans shifts through all the forward gears and goes into torque converter lockup.
6. Let off the accelerator pedal, and press the brake pedal to drop the vehicle speed to zero. Shift into
Reverse and then into Neutral.
7. Shift into Drive, and repeat steps 4 thru 6 four more times.
8. Set the parking brake, and repeat steps 2 thru 6 two more times.
9. Drain the trans, and reinstall the drain plug with a new sealing washer.
10. Refill the A/T with ATF-Z1/DW1.

Helps the trans fluid transfer through all solenoids, clutches, etc. and mixes in with the new fluid. In the end you will have clean fluid. Using a "flushing machine" is NOT recommended on these cars, or any cars particularly.

Another video that I created. 1x3 drain / refill.

With all due respect, Turbonut is the only one that gave a coherent answer.
The question was whether it matters if I shift through the gears in the air or on the ground.

So why the videos and the links? ...
I already went through the links and more threads that discuss transmission fluid 3x3, but I don't think a similar question came up.

@alexb92 nobody ever mentioned using a "flushing machine". Where did you get that from? Did you read the question...?

Many times I wonder if people even read more than just the title before responding on some of the threads I read.

oh was it? was the question "why is it necessary?" weird bc you never asked "why" in your opening post. sorry were not mind readers.

take it easy cowboy. instead of changing your ATF, go get laid instead. sounds like you need it.

fwiw, a simple google search would have given you plenty of answers why it's necessary to drive around between each drain/fill.

If you don't need the 'extra' help, good on ya.

Others might find it useful though.

@SharksBreath there's no need for free insults. In the first post, the question clearly implies that I know it is recommended to drive it and I was asking if I can't just do it in the air. However, maybe I wasn't completely explicit as you say. Again, after doing searches, I wasn't able to find a similar question.

@Bearcat94 I didn't intend to start a controversy, it just looks many of the users don't read the (entire) questions before posting and you can see this in many threads, not just this one. Maybe they are just interested in their number of posts and the progress bar.

Anyway, yesterday ended up doing 2x3 and I'll do the last one in a month or so. I drove a few miles in between the changes.

Thanks.

I don't wanna start a new thread.. There's plenty of results on the forum on how to do this, but I can't seem to get a straight answer on what fluid everyone suggests to use?

I see a ton of I use this, I use that.. But not a really consistent you should use this or stay away from this fluid?

I've seen things from GM to Acura/Honda to Redline?

People's preferences differ. Some will have positive experiences with say, Acura fluid like myself, while others like the GM fluid, while others like the generic brand. It's determined by your wallet and experiences.

I've never had a problem with Honda/Acura fluids, so I tend to stick with them.

That's because there is no straight answer. It's all about opinion & preference. Maybe a little objective observation and supposition here-and-there.

FWIW, I'm pretty sure (99.9%) the GM references you saw were for a 6MT, not an auto trans, so throw that one right out.

Haha thanks, I literally spent hours last night going through the garage and pickup up threads to look at to just try and learn more about the car.

I need to do the 3x3 just wasn't sure what fluids were "recommended" :/

The normal recommendations are:

- Current Honda Fluid (DW-1??), or

- An Amsoil, RedLine Racing or Royal Purple quality Honda compatible fluid, or,

.... If you understand the rationale and potential risks, ....

- RedLine Racing Type-F (usually) mixed with RedLine Racing Honda compatible fluid per your determination based on Inaccurate's and IHC's trans fluid/switches threads.
