Valvoline Extended Protection Full Synthetic Automatic Transmission Fluid ATF 1 GA, Case of 3

I have a 2011 Silverado C1500 with a 6-Speed transmission that currently has 65,000 miles and had never had a transmission fluid flush/change. The transmission seemed sluggish to downshift and when it did there was a hard shift. In addition it didnt always want to down shift right away when coming to a stop. I changed the transmission filter then flushed 4 gallons of this transmission fluid through the transmission before the fluid started coming out bright red. The old fluid was not burnt, however it was dark and needed replaced. I drive the truck lightly and it does have the tow package with the transmission cooler. Before on long trips it was not uncommon to see the transmission temp at about 200 degrees. After chaning the fluid I have not had the transmission temp go over 175 even when driving it hard. In addition, it now shifts like it did when it was brand new. We are taking the truck to Colorado next week and i knew with the elevation of the mountains I really needed to get this done before our trip. I will provide and update when I return and let you know if anything changes.

first i tried the little tiny 1 liter bottle for my power steering fluid, helped alot after drain filling out the old fluid. so i bought 3 of the big jugs, and MAN, it did wonders on my 2010 subaru forester 2.5x with the 4 speed 4EAT. my transmission is still going to need a rebuild at some point but man did it help, especially in cold weather (-10f with windchill)

i have done transmission service complete exchange with 16 quarts it is been one month since i have finished service so far it is been driving perfect even better than before no issues for toyota honda suggested using this transmission oil

Above average transmission oil extra additives top of the line super price awesome.

Used this for a full exchange on a 19 Silverado 6l80. Great price for the 3 Gal combo.

Great price
