2008-2020 Toyota Sequoia ATF Change How-To

This is a how-to for the 2008-2020 (Gen 2) Toyota Sequoia’s automatic transmission fluid (ATF) change. Really standard drain and fill here.

A few notes – Toyota WS has been proven not to be a great ATF. You can search on BITOG, but most people switch to Valvoline’s ATF with zero issue. I chose to use Red Line, as I think their ATF fluids are among the best. The total system probable takes 3-4 gallons of fluid. I’m choosing to flush 4qts at a time, which I will do at regular intervals. I’ve done the full flush where I steal from the return line and completely clean out the system, but I don’t think it’s that valuable for the work. The pictures I took weren’t great, but again this job is really straightforward.

Items/Tools Required:

3T + jack & stands or ramps
14, 24, and 22mm socket
4qts of ATF (I chose Red Line D6)
Fluid pump
Drain pan

Step 1: Get the car up & wheels off. Use appropriate jacks & stands, and the lug nuts are 22mm.
Step 2: Locate the fill plug. It’s a 24mm that sits above the pan itself on the driver’s side. The pan looks similar to the engine oil pan. Make sure to always loosen fill plugs first.
Step 3: Locate the drain plug in the rear – it’s a 14mm. Drain the ATF. Approximately 4 qts will come out. I didn’t bother to measure the amount – just drained and added 4qts. Close after draining.
Step 4: Add back the amount of ATF that was lost. I used a pump to add through the fill hole. Once complete, install the fill plug again
