Transmission Flush in SoCal recommendations ?

I have a 2016 5.7 Tundra 4x4 with towing and trans cooler.
I have been meaning to do a filter/screen , pan gasket and full flush myself but havnt gotten around to it, and my driveway is not level so going through the fluid level check valve process may be a little difficult.

Can anyone recommend a knowledgable person or shop in southern california who can do this properly , someone who has done this before on these trucks

 

A full transmission flush isn't thought of too highly around these parts. Many find it causes more problems than it fixes. The three qt +- drain and fill seems to be the way to go. You do get more fluid out when you pull the pan but pan bolt breakage is common when removing the pan.

Sorry I didn't answer your question as asked.
