Lubegard63010 Platinum Automatic Transmission Fluid Protectant, 10 oz.

I have a GMC 2018 Denali with a 6.2 engine and 8-speed transmission. At about 45,000 to 50,000 miles, I started getting this shutter when leaving stop signs in traffic lights. Also, it started bucking between gears. At first, I thought it was the road, but one day I had to give my wife a ride to her appointment, and she says to me, "what the hell is wrong with your truck?" Lol, she has always had problems expressing her thoughts. That's when I realized that it was the truck and not the road. I called a GM dealership and they had a technical bulletin that suggested flushing the transmission fluid and adding a new transmission fluid that should fix the problem. And it did for about 10,000 mi. About 3 months ago, it came back with a vengeance. A stronger shutter and bucking between gears. Especially when slowing down. I had known about lubeguard, but I thought it was probably just a gimmick. I have a very busy job and it's hard for me to get my truck to the dealership. I called them first and for some reason, they didn't have any information about the flush that they did. I knew it was going to be a hassle. So I read a little bit more about this lubguard and decided to order 2x20 oz bottles. 40 oz As recommended. I also ordered a cheap pump. If your like me and put things off because, well because. Let me tell you what I did.Pulled my truck into the garage, I got a 10 mm wrench, ratchet with 10 mm socket and a pair of needle nose pliers. In order to add this fluid you have to get to the fill plug which is behind the heat shield. You only need to take off the front top bolt and front side bolt. After that, you can pull the shield down exposing the fill cap. Next, I couldn't figure out how to make sure that I only took about 40 oz of transmission fluid out of my truck. I decided to just get a Tupperware bowl and pour one of the lube guard bottles into it. I took that empty bottle with me under the truck. I loosened the drain bolt, positioned my drain pan, and quickly caught the oil with the bottle after removing the bolt. I filled The bottle to the same point as where the LG oil was. I put the drain screw back in, dumped out the fluid into the drain pan, and then undid the screw and caught another 20 oz. After that, I put the screw back in cleaned up any oil, and slid the pan out of my way. I used a rag to clean all around the fill cap before removing it. I didn't want any debris falling inside. After that, I sliped my arm around the exhaust pipe with a pair of needle nose pliers. After a few attempts, I was finally able to remove the fill cap. Went to the front of the truck and pop the hood. I grabbed my new pump and slid the drain side hose down through the engine compartment, close to where the fill cap was. Went back under the truck and placed it inside the fill cap hole. Went back to the front of the truck and put the suction hose inside the Tupperware that I use to hold the first bottle of oil. Turned it on and sucked all the oil out of that. When it was done, I shut the pump off checked underneath the truck to make sure there was nothing spilling. I grabbed the next bottle and pump that one in. After I finished, I cleaned up any oil that may have spilled around the engine compartment. Which really wasn't any. Went back underneath and took the drain hose out of The fill cap hole. Cleaned the fill cap and pushed it back in. Bolted the heat shield back into place and wipe down any wet areas.Clean up the tools, wrapped up the hoses and put everything away. I started the truck and hoped for the best. Now this is only a day but I am not kidding, 95% BETTER. I was shocked, It was better right away. I cannot predict how it will be down the road, but I did read a lot of forms about people that did this and some claim to be over 40,000 mi since adding lubeguard, and still have not had a problem. All I can say is, as of right now, awesome!

New sealed bottle of fluid treatment formulated to help with the GM 8L90E and 8L45E transmission issues like shudder and harsh shifting. I’ve not tried it yet but a transmission shop recommended it for my Camaro SS.

took 2017 Cadillac Escalade to "reputable" mechanic and was told I needed a new transmission at a cost of $7000. Did some research on the internet and found Lubegard. $30 and 15 minutes of my time adding it to my transmission fluid and problem solved. Not sure if it will cure every issue, but sure cured mine.

Seeing as GM is the new leading name in garbage transmission designs, I can comfortably say this is a game changer. I have personally used this product in dozens of 8 speed transmissions and specifically I used it on my brothers personal vehicle. It resolved all shuddering almost instantly. I have been a long time Lubegard user, and I can proudly say this is a product I stand by!

Good product so far, pour into truck and drove couple hundred miles. Definitely worth the money.

I don't have any shifting issues. I was just looking for more performance and protection on a car with 170,00+ miles. After about 100 miles it smooths out the shifting. Whether you have a low or high mileage car it is good insurance. I use their oil additive and power steering additive as well. If you aren't having issues yet I would use this before using the red.It has a great additive package and will give you peace of mind on a high mileage car.

Excelente

Helped out my old Tacoma immensely. On the recommendation of a transmission guy who’s an expert on Toyotas, dumped a bottle of this in with about 6 quarts of fresh ATF exchanged with a new filter prior to the lube guard addition and the mild but very audible noise that the trans was making is much quieter almost non existent. The friction modifiers gave whatever the unidentified unhappy component what it needed.
