Transmission parts are one of the least forgiving categories for guessing — here’s how to buy the right thing the first time. You can also use our Fluid & Filter Lookup tool to check your vehicle directly.
Transmission fluid type (ATF, CVT, DEXRON, MERCON, ATF+4, and others) is specific to your vehicle’s transmission, not interchangeable by preference. Always check your owner’s manual or the fluid’s listed compatibility before buying, even when a fluid is a strong overall seller like Castrol or Valvoline MaxLife.
Tube-and-fin coolers (like EVIL ENERGY’s lineup) work well for daily driving and light towing, while stacked-plate coolers (like Mishimoto’s) handle more heat for towing and performance use. Size the cooler to your GVW and towing needs, and confirm it fits your available mounting space in front of the radiator or A/C condenser.
Filter and rebuild kits are transmission-model specific, not vehicle-model specific — the same kit can fit several different vehicles that share a transmission (like the 6L80E across multiple GM trucks and SUVs). Confirm your specific transmission code, usually found on a tag on the transmission case or in your vehicle’s build sheet, before ordering.
Match the jack’s weight capacity to your transmission’s actual weight plus a safety margin, and check the lift height range against your vehicle’s ground clearance. A low-profile jack (like Garvee’s) is worth it for lower vehicles where a standard jack won’t fit underneath.
This guide and the Fluid & Filter Lookup tool are not a substitute for your vehicle’s service manual or a qualified transmission technician. Always confirm fluid type, part numbers, and torque specs against manufacturer documentation before performing transmission service.
