Transmission fluid change tutorial and part numbers - Toyota 4Runner Forum

I'm planning to change the transmission fluid of my 16 SR5 4WD myself soon. I want to replace the filter if possible, which means I need to take off the transmission fluid pan. Don't need a complete flush. Anyone knows if there's a detailed write-up with step-by-step instruction and all part numbers needed? There are some videos but no detailed part numbers included.

A related question is which diagnostic tool/OBD reader is recommended to read the trans temperature. I saw it somewhere but can't find it now. I also have a 17 Tacoma and hope the scan tool can be used for both trucks. I do have a temperature gun. Will it work if I just point at the pan to get correct trans temp needed?

Go here: DIY maintenance quick reference - Toyota 4Runner Forum - Largest 4Runner Forum

Scroll down to "Replace Automatic Transmission Fluid" Part numbers are listed and there are 5 links to further discussions that will likely answer all your questions.

I don't replace the "filter". It's a large surface area screen for catching chunks. The super fine stuff in suspension passes through it.

Here's a good one by a member and former master tech: Comprehensive Guide to 5th Gen 4Runner Trans Service

Thank you for the info. I've watched the video and read the quick ref too. Got most of the P/Ns but need the last one for washer of the 10mm pan bolts. I searched but couldn't find the exact item online.
