@Jacques Albrecht has peported in this thread that the Foxwell NT710 performed the hydraulic system flush on his 2020 C8 however couldn't perform the post filter replacement leak check.
They must have updated it recently, then. Because there were multiple reports it just returned an error message.
After purchase, I charged the NT710 internal battery, set-up it's wi-fi feature to my home's wireless Internet, updated the unit's software to a current version and once all of that was completed.... I plugged it into my Corvette's OBD port and performed the processes request on the scanner unit screen to finally accomplish the 'hydraulic system flush'. No other external program / software was downloaded or used.
So you did not have to download the GM software that is optional? $80
Never-mind I figured out what I did wrong. I ordered one with Mercedes software instead of GM.
I didn't realize they came with one or another preloaded.

You're correct this NT710 has a number of optional auto manufacturers listed and you only need to select GM or BMW or whatever car software you need to work with at the moment.

Can you post up a picture showing what software version you have on the NT710?
I was one who had the unit fail previously (2021 MY). I'd be happy to purchase the unit again, update it, and test it because the function simply wasn't in the menu item last time.

My OS version is V1.3.8
My App version is V1.24.002
I just updated everything yesterday

Can you post the exact test name on the NT710 you used to do the transmission hydraulic system flush procedure. I see a TON of different options but not one that Im sure is the proper test.
Never mind, I think I found the test I needed from an earlier post. Even though it has the error hopefully ours wont.
Well, I'm back and posting about the NT710 (again).
I drove my 2021 C8 to work today and in the parking lot tried to conduct the two transmission tests.
tl;dr - The system flush procedure returned an error, but did appear to actually be running & the leak test provides only an error.
Long version below:
First... I own a device which has worked just fine for my C8 and I've tested the NT710 before with neither of these functions working.
Upon trying to start the hydraulic fluid flush, the device returned this error. Yes... all criteria were met (temp, in Neutral, and brake fully applied)
After selecting the "OK" button on the screen, the test *DID* seem to actually start.
I did not let the test complete as I've just recently replaced the fluid and it's not needed to be done. I simply selected "Cancel" and about 30s latter the test ended. I have little reason to believe the test would not complete though.
I then tried to conduct the leak test, but was presented with a similar error screen.
If you look at the picture it appears I did something wrong... BUT I DID NOT. The previous test (hydraulic system flush procedure) is still selected, but the error box comes up when I selected the option below (#3 hydraulic system leak detection). Every time I selected option #3 this error box would appear, and option 3 never turned blue. It's as if the option itself is not able to be selected.
Hitting OK does not proceed to start the test, it simply returned me back to the menu.
Here's the software information from the device:
My take is the NT710 still does not operate as Foxwell states it does. There are other similarly priced options out there that do perform all of the functions (clones of the BOSCH hardware), but it's a user decision as to what is important to them.
2020-2022 C8's and all 2023-later C8-Z06/C8-ZR1 vehicles require a J2534(CAN-FD/DoIP) interface such as Bosch MDI-2, Opus Mongoose, or other J2534 pass-through interfaces running in conjunction with GM GDS-2 software on a Windows laptop with compatible hardware drivers. This is the ONLY method for programming, bi-directional, and calibration functions on these encrypted GM Global-B Corvette's.
There are no hardware only plugin scan tool's that can work with these vehicles for advanced functions because the encryption, security management, programming, and control functions are contained in the GM GDS-2 software, not the hardware interface.
2023-later C8 Stingray/ERay introduced an updated E99 ECM compared to previous models. This new ECM contains most (but not all) advanced service function software stored in encrypted onboard nvram. With this ECM, a hardware only scan tool will work for many functions because J2534/CAN-FD/DoIP protocol is not required as on the 2022-earlier C8 ECM's. A compatible scan tool (such as Launch Creader) still requires GM specific canbus command formatting, but the tool simply issues an api function call to the ECM's internal programming that then securely executes the command. No patented/proprietary GM software code is exchanged, and the GM Tech-2 was the last scan tool that contained any patented/proprietary GM software.
Module replacement, programming, software updates, odometer programming, etc......these all still require GDS-2/SPS2 software and a compatible J2534 interface regardless of model year.

Don't disagree with you at all, and it's why I have gone the J2534 interface route.
The discussion here has (recently) been about what the NT710 unit from Fox well can and can't do... that's all I was reporting on.

See post #95. @Jacques Albrecht managed to perform the hydraulic system flush on his 2020 using the NT710.

Cool. This functionality is not something that varies by car. Technically, third party scan tools should not be able to do advanced functions on any pre-2023 Corvette.
After purchase, I charged the NT710 internal battery, set-up it's wi-fi feature to my home's wireless Internet, updated the unit's software to a current version and once all of that was completed....

Please list step by step exactly what you did to accomplish this.
Launch is the oem software behind many third party scan tools. The Foxwell screens look identical to the Launch Creader tools, and Launch scan tools do not work for advanced functions on 2020-2022 Corvettes. The NT710 errors shown are consistent with the same error Launch tools display on these cars.

Was this done with the car running or off? I'm wondering if it may need to be running?

I know exactly what happens during the DCT flush because I have done it. Until @Jacques Albrecht posts a step-by-step procedure with pics of exactly what happened during his alleged flush procedure with the Foxwell scan tool, it did not happen.
