Elmer is right!

The triple flush worked for me and I still have the advantage of increased fuel economy. I called ahead for an appointment and took the TSB with me to a dealer. They had me in & out in 2 1/2 hours. I didn’t buy my Vette for fuel economy but at nearly $5 / gallon every little bit helps.

Semper Fi and good luck!

How much better? I did the triple flush but no difference in mpg.

I was referring to use of the ‘Range” device that overrides the change to 4 cylinder mode.

I doubt the range can improve mileage. A push at best if you mostly drive in V8 mode but without it, potentially gas savings by dropping into V4 mode so not sure how it saves gas. If anything, gas consumption goes up since it is always in V8 mode.

Range does not improve mileage. It keeps the engine burning fuel in 8 cylinders and the V4 mode allows it to run on 4 cylinders with fuel in them.

THe mileage comment was the tranny fluid change (I thought??) I'm not sure how that would affect mileage but I've got the A6 and don't need to flush.

I also had the flush on my 2016, even though there were no issues apparent. I had it done because it was free and to prevent future issues.

I had the flush done to my 2015 (13K miles) in January. It made it shift much smoother, and it lost the shudder.

The flush worked for me and the normal shifting was noticeably improved. Highly recommend it.

I have a manual, so I never feel any shutter. But I'm lucky that in Tour, Sport or Track it is not activated. I put it in Eco once when I first bought it, just to see if it works. But will not put in in Eco again. The car gets great gas mileage without Eco. Also having 4 active cylinders driving 4 dead ones seems to me a way to induce stress on the drivetrain. My neighbor that had an A8 had terrible shutter. Triple flush fixed it.

Manuals don't have the need for the triple flush. If you do get shudder, it's the clutch facing and the pressure plate rubbin and fussin. Sigh, I miss my manual transmission until I have another surgery and can't drive the darn car unless it is an Auto. Old age, the golden years, shiiiiiiiit.

Sorry to hear about the aches and pains. Yes I know manuals do not need the flush. The only time it will shudder is if I screw up a shift!

Apparently you didn’t read the entire comment. I said “Elmer was right.”

The Range device doesn’t correct the problem. It masks it by not allowing the engine to switch to V4 mode. Remaining in V8 mode consumes more gas!

Do the triple flush. I could tell the difference in shifting as soon as I drove it home. Fortunately mine was still under warranty.

RANGE WILL NOT PREVENT OR CURE ALL 8L90 TRANSMISSIONS/TORQUE CONVERTERS THAT SHUDDER.

I have posted this on this forum many times before. The Range may mask or improve some transmissions that shudder but it is NOT a cure for all instances of shudder. My AFM deleted LT1 started the shudder after many miles of running in perpetual V8 mode. The triple flush with the new fluid fixed it.

And please stop bashing this transmission. It is an excellent 1000hp trans. It’s the ridiculous AFM design and torque converter control strategy that’s the problem. Few have had transmission failures. Many have had problems with torque converter shudder.

I have a 2016 Z51…when the shudder started I took it in for a transmission flush and there was no change…this was before the new fluid update. I used the range device until the new fluid came out, then took the car back in for the triple flush. The result was amazing, no more shudder and I stopped using the range device. Currently the car has over 25,000 miles and shifts like butter. I believe the fluid was the culprit.

As I said earlier, the flush not only fixes the "shutter" but also results in much smoother shifting. I doubt that the range device has any effect on the actual shifting of the transmission.

Correct. It is a $200 device that only inhibits V4 mode. Nothing more. Nothing less.

Knowing what I know today that it does it by affecting the readiness monitor and I have already kicked it out of the car twice, I am looking for a programming solution to keep it out of the car. Anyone know a programmer that can do it?
