Hi, welcome to the forum.
Is the car new to you or is this a new problem with the car?

The car is new to me. I call the dealer (kia) where i bought it and they send it to GM. They change the 02 sensor the car shaking is a lot less then it was but still has vibration sometime. My friend told me it might be the oil transmission. In 2019 GM change the oil transmission with a new kind of oil which help but not resolve the problem but help it a lot. But i'm not sure if this is the problem.
Hi and welcome. I took a look and found this using Perplexity as recommended by @Jack Raccoon! It refers to the TX fluid change as well.
A 2016 Corvette shaking that appears to come from the transmission is commonly linked to a known issue called “Torque Converter Shudder” in the A8 automatic transmission found in C7 Corvettes. This shudder manifests as a vibration or shake during acceleration, often between 25 and 80 mph.
General insights and steps to address this issue include:
• GM has recognized this problem and issued Technical Service Bulletin (TSB) 18NA355 covering a change in transmission fluid specifications to address the shudder.
• The most recommended fix is a “Triple Flush” of the Red Label Mobil-1 automatic transmission fluid. If done early enough, this flush can permanently resolve the shudder.
• If the fluid flush does not fix it or the issue has progressed, further repairs such as torque converter replacement may be necessary.
• Some owners have also reported the need to replace a specific internal transmission part called the driveline support, which may become bent and contribute to the shudder.
• It’s important to rule out other causes of shaking such as wheel balance or alignment, which can mimic transmission vibrations.
• If the shaking occurs at idle rather than while accelerating, it might be from engine misfires, vacuum leaks, or worn motor mounts, rather than the transmission.
In summary, for a 2016 Corvette exhibiting transmission-related shaking or shudder, the first step is to check if the triple flush of transmission fluid has been performed and have it done if not. If the issue persists, diagnosing and possibly replacing the torque converter or related drivetrain parts is advised. Also, ensure wheel balance and alignment are correct to exclude those as causes.
If the shaking is at idle, investigate engine and motor mount issues rather than the transmission itself.
No problem. I hope this helps and you get it sorted quickly. Summer is too short ! Take a look around your area for a fairly high volume Corvette dealer as they most likely have encountered this problem before and would no doubt be better suited to diagnose the issue than the KIA dealership.
My 2019 Grand Sport with A8 had the shaking issue. Tranny, torque converter were flushed and that fixed the shaking for about 2000 kms. The dealer then changed the torque converter and that solves the shaking problem. If it is not under warranty, it is an expensive fix.
Most of the C7 A8's had this problem with various GM fix options tried with most not solving the problem. I never considered an automatic and that's one more reason I'm glad for that.
I had the same A8 tranny in my 2015 Silverado without issues. Some have theorized that it is caused by the torque tube from the bell housing to the transmission input.
It always felt like a rear tire out of balance.
The concern for future repair bills is what motivated me to buy the Camaro. The C8 was beyond my budget.

By the way.... There is no such thing as a Corvette LT3 engine. Whoever told you it was an LT3 didn't know what they were talking about.
For those who are curious….
Here is a comprehensive list of Chevrolet Corvette engines since 1953, highlighting major engine types and their years of use:
• 1953-1955: Blue Flame Six, 235 cu in (3.9 L) inline-six, 150 hp (first Corvette engine)
• 1955-1981: Small-Block V8 (First Generation), 265 to 350+ cu in, power range approx. 195-375 hp
• 1965-1972: Big-Block V8, including legendary variants such as:
• L71 427/435 hp
• 427 L88 430 hp (high-performance, rare)
• 427 ZL1 (aluminum block race engine)
• Can-Am 430 hp
• 1970-1972: LT-1 Small-Block V8, 370 hp, high performance with solid lifter
• 1982-1984: Cross-Fire Injection V8, 200 hp (early fuel injection)
• 1985-1991: L98 Tuned Port Injection V8, 230-250 hp (improved fuel injection system)
• 1997-2019: LS-series Small-Block V8 family, including:
• Various iterations culminating in the 2019 ZR1’s LT5 supercharged 6.2L with 755 hp
• 2008: LS3 6.2L V8, 430 hp (C6 generation update)
• ZR1 (2009): LS9 supercharged 6.2L, 638 hp
• 2020 onwards (C8 generation):
• LT2 6.2L Small-Block V8, 490 hp, with dry sump lubrication system
• New LT6 5.5L DOHC 32-valve V8 for Z06, 670 hp, flat-plane crank design, most powerful naturally aspirated Corvette engine ever
• Electric Assist: Recent electrification with e-AWD working alongside LT2 engine (C8 Z06)
Earlier Corvettes (1953-1954) lacked a V8 initially and were powered by the Blue Flame Six until the introduction of the small-block V8 in 1955, which defined Corvette performance for decades. Over 70 different V8 engine versions have been used since, evolving through first and second-generation small blocks, big blocks, LS and LT series, and the latest advanced flat-plane crank engines.
This list captures the key engine milestones through all Corvette generations, from the original inline six to the mid-engine LT6 flat-plane V8 currently used in the Z06.
And of course the LT6 twin turbo version in the ZR-1 .

Beg to differ but the LS series did not extend past 2013.
My 2017 Stingray Coupe and 2019 GS had a LT1 455 HP. Z51 version was dry sump.
My 2024 Camaro SS has the same LT1 455 HP

That’s what you get when you copy and paste from the internut……took another look at the source and they usually give footnotes or links but this time only a few links which don’t seem to be pertinent. Took another look and found an article on Road and Track but unfortunately paywalled. Looked like a good one too . Oh well.

Appears one must be a Road and Track member to see it... either that or I really need glasses...
Yes, here are a bunch of specs that look pretty good.

Learn all about the Gen 5 6.2L LT1 engine, including LT1 horsepower, LT1 engine specs, history and much more!

Correct. Although I'm surprised your GS and SS wouldn't have had the performance exhaust which brought the HP up to 460.
I made an edit to point that out. A drag these paywalls.
Quite a stretch for GM to call an exhaust that adds a whopping 5 HP “performance “ like they also do with the C8 . They should just say “ a slightly louder exhaust “ , lol.
Lol... An NPP exhaust is more than noise... the system also optimizes the air-fuel ratio in the combustion stage for that increased HP and added fuel economy... The added sound is just an ear candy bonus....
