TL;DR GM's officially licensed DEXRON-VI from America's top-selling ATF brand. Covers 2006+ GM automatics and Ford MERCON LV applications with a documented anti-shudder additive package. BITOG confirms shudder elimination in GM 6-speed applications, and owners rate it highly.
Valvoline's DEXRON-VI / MERCON LV ATF is a full synthetic fluid built from hydrotreated heavy paraffinic base stocks, carrying the label "Officially licensed and GM approved DEXRON-VI fluid." The back label calls out enhanced anti-shudder protection, and BITOG transmission threads confirm shudder elimination in GM 6L50, 6L80, and 6T40 automatics after a drain and fill. Ford MERCON LV compatibility is explicitly claimed and consistent with the product's long history in both GM and Ford applications. The gallon is the practical choice for a full drain-and-fill on most 6-speed GM automatics, which take 7-9 quarts with a pan drop.
Right choice for 2006+ GM automatics (Chevrolet, GMC, Buick, Cadillac) requiring DEXRON-VI and Ford vehicles requiring MERCON LV. Confirm your spec in the owner's manual before purchasing. Skip if your vehicle requires ZF Lifeguard, Toyota WS, Honda DW-1, or a modern DCT fluid.
SDS §2 classifies this product as not hazardous. California Proposition 65 warning applies due to trace residuals from petroleum processing (propylene oxide, 2-ethylhexyl acrylate at <0.1%). Dispose of spent ATF at a used-oil collection facility.
Yes. The back label explicitly states 'Officially licensed and GM approved DEXRON-VI fluid.' This is a genuine OEM license · not a 'meets spec' or 'recommended for' claim. It means GM certified this specific formulation and Valvoline pays for the license to use the DEXRON-VI name.
Valvoline states 'Recommended for Mercon LV applications.' Ford discontinued its Mercon LV licensing program around 2013, so no fluid can currently hold an active Ford Mercon LV license. Valvoline's explicit compatibility claim is credible for a product in long-term dual-spec use. Always confirm your owner's manual spec first.
DEXRON-VI is the specification for most GM 6-speed and newer automatic transmissions from model year 2006 onward, including the 6L50, 6L80, 6T40, 6T45, 6T70, 8L45, and 8L90 used in Chevrolet, GMC, Buick, and Cadillac vehicles. Consult your owner's manual · the dipstick tube or fill port may also have the spec printed on it.
A typical pan-drop service on a 6L80 or 6L50 takes 7·9 quarts of new fluid. A complete flush (torque converter included) takes 10·12 quarts. The 1-gallon size covers a single pan drop; buy two gallons for a full flush.
Many BITOG forum members report shudder elimination in GM 6-speed applications after a drain-and-fill with Valvoline DEXRON-VI. The back label explicitly claims an anti-shudder additive package. Results vary by vehicle · shudder caused by hardware wear may not resolve with fluid alone.
