2018 ECU reflash

I've followed various treads regarding getting the dealership to install the latest version but I'm still a bit confused. Mine is a 2018 I purchased in January (Built in San Antonio) Nothing has been messed with regarding the ECU. Around town it shifts pretty well no matter what mode I drive in, which is usually S5 and sometimes with ECT activated. A few times driving on the freeway I did get a little annoyed by the gear hunting while in D mode. I don't do a hell of a lot of highway driving so my sample size is small.

So, I have an appointment on Thursday to get the tire rotation and other scheduled maintenance done and would like to have them install the latest-greatest. What specifically (TSB etc) do I request?

 

The will apply what ever one applies to your Vin number. Mine was built 2/18 and I got tsb58.

 

Request TSB 0062-18
or TSB 0058-18... there the same update its for your transmission I believe .. it’s a great update!! MY taco drives alll around smoother and a lot less hunting.

 

My automatic was built in San Antonio in July. I had TSB 0058-18 downloaded and I'm thoroughly pleased with what it did to my truck!

 

I had TSB 0058-18 done at Tustin Toyota yesterday. There is a difference in the shifting. It doesn't seem to go into 5th and 6th as quickly around 40 like it did previously. Going on a road trip on the weekend hoping an improvement will be more apparent.
