Yes. Mine's 100 miles old. Stock-like engagement/disengagement with minimal pedal pressure increase.
More positive shifts now.
The installer was an ex-pat Dodge tech who was very impressed with the product quality. Before this he had only reinstalled the stock dmf in Dodge's at the dealership.

Gonna baby it for 500 miles.
You'll like it.

we run a fleet of them set up this way. most are set at 425 hp 850 ftlbs. the one in my sig is 450hp 900 ftlbs. while you have the g56 out mix one gallon sae 50 synthetic syncromesh transmission fluid with one gallon 5w-30 synthettic syncromesh transmission fluid and use 7 quarts in the g56. we tow very heavy and have several hundred thousand miles on the southbend conofe. single disk.

i just copied this from another post. while you have the g56 out, replace the red rubber boot on the shifter.here you go: Moose Fast Boot II part # 0213-0427. $17.95. Available online or at your nearest ATV shop. Add a #48 hoseclamp to the bottom and you're done.
This is the one Mercedes should supply with the G-56.

Carl,you're in NM which must experience some pretty cold mornings in the winter as we have lately. With your fluid combo,how's the cold shifting first thing in the morning? My G-56 has always been sticky shifting from reverse to 2nd initially in the morning and the whole thing's stiff for awhile. I'm running Pennsoil Synchromesh.
Thanks

in ruidoso this morning when i got up it was 2* below zero. it shifted ok. a little stiff for about a 1,000 feet. the gorilla juice or the sae 50 alone does not shift for 20 miles. in the cold. at 20* below zero, this formula worked good. not to much harder than the penzoil.

Can't speak about this exact setup but have 240k on an OFE in my NV5600. Nothing but the highest praise for the product and the customer service provided by South Bend. I've never experienced any slipping with my clutch and I've been continuously modifying the truck since the installation.

Somebody else posted that Zoro Tools carries it also. I got on their website and couldn't find it. You might Google that in and call them. They were considerably cheaper than Grainger where I obtained mine.
