A Toyota master diagnostic explains Toyota Trucks sealed transmission fluid replacement WITHOUT a scan tool using the Fluid temperature check mode built in most Toyota trucks with overflow type transmissions.

In this video we revisit the Toyota sealed transmission fluid replacement procedure without a scan tool.

Many folks dislike the dipstick less Toyota transmissions. And while a dipstick is much easier, once you watch this video and practice the procedure you'll realize how easy it is to do this. You'll need very basic tools, some time to practice the procedure and a bigger wallet to carry the cash you save from paying a shop to do this!

I always recommend that you use Toyota original fluid. Almost all Toyota and Lexus sealed transmissions use Toyota WS ATF fluid. Some of them will say Life Time fluid. That from experience is not very accurate and some of these transmissions start having issues as they age and have more miles. Play it safe and change this fluid every 60,000 miles or 6 years.

The tools you'll need for this job :
- 14mm socket
-5mm hex socket
-small piece of wire
-graduated bucket or pan to capture the fluid and measure it.
-fluid transfer pump

Most Toyota and Lexus trucks are high off the ground enough where most folks will be able to do this without lifting the truck. However if you need to lift it make sure it's on a level surface and all 4 corners of the truck are lifted to make sure the level is accurate.

On Sequoia, Tundra and LX570 models don't forget to bypass the external transmission cooler thermostat if equipped!

If you are watching this video and you don't own a Toyota truck but own another Toyota or Lexus model with a sealed transmission, Review this older video I made on sealed transmissions.

Do this job right and check the fluid level, I don't recommend you use the temp gun method as I explained in the video because it's highly inaccurate in Toyota trucks.
