I don't think so. Not in my experience. All it does is fool the ECM into not running AFM because the readiness monitors are not in readiness state. Probably why you have to drive around for emissions testing with it off for a while. I sold it and got the Diablo I3. Regardless, your transmission is as strong as it is. Nothing can make it stronger besides tearing it down and beefing it up. The I3 can make it firmer and adjust the throttle tip in so you don't have to buy the Soler TB for the same effect, I imagine.

Only a change of fluid can stop the transmission shudder, assuming it isn't too far gone. However, if can mask it so you don't feel it as much till too much water gets into the fluid. I suppose a new transmission would fix all the problems.

I have had the range in my 2019 for 4 years . I was just wondering something though. I know you can put the car in "M" mode and it will not go in to 4cyl. So if you are in drive mode and get on the freeway I assume you could just put it in manual mode while going 70mph and it would stay in 8cyl ?

I bought my Corvette for several reasons. One of which is the power when I want. If the lifters were good, I don't care what it does when I don't need the power.

IIRC in one of the range device associated threads, one poster put it out there that because the device prohibits the designated lifters to do whatever they're designed to do it might be a good idea to unplug the device every so often, 3K miles or so (?) to allow the system to work as designed for proper lubrication and allow what was designed to move, move. I do that a few times a year for maybe 150 miles then at the next startup cycle I plug it back in.
Just an idea.

Strange thought, 99.9% of the M7 Corvettes never 'oil or exercise' the lifters and don't show any more unusual wear of the said lifters..................
Shouldn't they all be failing?
Huumm......

Ok, going on pure geezer logic, I'm guessing that if it moves, it gets oil. It might not get gas or spark but oil seems like a good thing to slosh around on any moving parts in the engine.
Active Fuel Management (AFM), which shuts down the LT1’s firing cylinders from eight to four by disabling the valves to the cylinders. When AFM initiates, the engine turns the 6.2L V8 into a 3.1L V4, shutting down cylinders 1, 4, 6 and 7, and firing only cylinders 8, 2, 5 and 3 in that order.
Otherwise, the complete firing order is 1, 8, 7, 2, 6, 5, 4, 3.
That's it, all I know. Going back for another cup of coffee.

The Range devise does nothing to smooth out shifting or make the transmission stronger. It eliminates AFM engagement, which in turn, helps to eliminate shudder. If you are feeling a shudder I highly recommend having the triple flush done. Then after doing the triple flush, buy a Range devise (buy direct from Range Technology, never a used one from Ebay) and enjoy the drive.

Exactly what I plan on doing... came back from a 10 drive to Bowling Green, started to feel the shudder and rumble strip motions ... '17 GS.(20K miles) purchased 8 months ago and this was the first long term road trip.. have a Range Finder (purchased from them not Amazon) now but going to get the triple flush and see how it goes.... I just want to prevent shifting to V4...
