Transmission Fluid

Dexron, Mercon, CVT, and manufacturer-specific automatic and CVT transmission fluids.

14 products in stock(1 out-of-stock hidden)Sort by Ranked →

Transmission fluid lubricates the gears, cools the clutches, and acts as hydraulic pressure inside an automatic — slipping shifts, delayed engagement, or a burnt smell on the dipstick means it's overdue. Service interval varies wildly (30k on some, "lifetime" on others, which usually means 80–100k before it really degrades), and getting the spec exactly right matters more here than almost anywhere else on the car. Dexron, Mercon, ATF+4, CVT fluid, DCT fluid — they're not interchangeable. Check the owner's manual before you buy.
