    Great. So you are using the BLE+ (not just the BLE) and it works now? If so, I'm going to go that route also and hope I get it up and running. Sounds like the plus version may allow some additional monitoring on the Toyota so that's an easy $8 to spend just in case, but certainly don't want to get something that doesn't work at all!
    Thanks :thumbsup:

    My temps are at around 200-210F with zero load and stock tires. Verified with the torque app. Mine is a 2019, so it does not have a cooler at all that I can pin open, it only has the engine coolant warmer. Pretty ridiculous that Toyota would get rid of the cooler on all 2019-2020 5.7 Tundras. Temps just seem too hot. I want to install the earlier thermostat that the 2017 and earlier Tundras have, but I’m not even sure if the old parts will bolt up. Waiting for someone with a 2019-2020 to attempt the install and be the test mule. I would like to install one and run a huge stacked plate cooler in front of the radiator. These newer trucks don’t even have the A/C condenser heat exchanger so you would have to really do your research to add an external cooler and make it work. Not to mention my truck only has 10k miles so I don’t really want to di** with it, but I may not have a choice

    So why not just add an external cooler?

    Who cares about the 2017 or whatever engine coolant or a/c cooling for the trans? If toyota took it away, it must have been for a reason. Seemed like extra complexity to me which only leads to more failure points, not saying they occurred yet something caused Toyo to change their design. Keep it simple with an external cooler, if in a cold climate make sure to get one that closes itself off in cold temps.

    Luck and enjoy that Toyota. : ^ )))

    Good morning all,
    I have a 2016 Sr5 TRD that i will towing a Travel Trailer 5500lbs with. I bought scan guage II for it based on suggestions I had read in these forums. However, I cant get the Xguage to read the trans fluid temps. I have used codes from here but still dont get temps just rpms. Am i doing something wrong?

    I would return it and get this, https://www.amazon.com/dp/B076XVQMVS ($39.99), and download the OBD Fusion App ($9,99) and In-App purchase the Toyota 2016 Enhanced Diagnostics for $9.99 or the 1996-2020 Enhanced Diagnostics for $49.99. It will save you the headache. I can get Trans temp, Engine Oil, Gear, and so much more.

    What is the difference between the T16 enhanced vs. the 1996-2020 enhanced Diagnostics? The years covered rather than just the specific year? And what is the difference between that product and this one other tham a couple bucks? https://www.amazon.com/dp/B073XKQQQW/ref=cm_sw_r_other_apa_i_2RyVEbE6R5KQG

    Got this to work and I must say it is WAY easier to use than the scanguageII. Thank you @Mike19.

    A lot of you are worried about trans temp(understandably) but these trucks don't have very many(if any) trans problems stock

    Funny how after manufacturers starting providing digital readings for transmission fluid temperatures people started to freak out. The ATF has a flash point of more than 350 degrees. Temperatures in the 200-225 degree range are perfectly normal. The purpose of Tow/Haul mode on some truck transmissions is to change shift points and keep the torque converter locked longer to minimize heat buildup and prolong the life of the transmission.

    If you are really concerned then change out the OEM ATF for one that is TES 295 rated like Castrol TranSynd. TES 295 ATF has a duty life that is double that of TES 389 rated ATF in terms of miles driven and months between changes. But with light duty trucks like the Tundra I would not worry about it at all.

    Did you try the codes from the first post on page 1, post 1, the ones I posted, they worked on my 2015 Tacoma, 2016 Tundra and my current 2018 Tundra, and I'm still using them.

    Everyone is so worried about trans temps. I run my truck hard off road and deep sand gets the temps up to 240 or so. Changed my fluid for the first time at 75k and it was a little dark, but no burnt smell.

    Only reason I watch them is just in case something goes wrong. Same reason to watch oil and coolant. But Im not going to pin my thermostat or install a huge cooler :rolleyes:

    Just wanted to share my experience with pinning the thermostat. Recently put in a brand new transmission filter along with Amsoil atf.

    Did an 8 hour trip, multiple elevation gains, weather conditions were ~80F and sunny, loaded bed (400+ pounds - fuel, water, tools, Jack, full-size spare, etc), with a lift and 35 E tires and pan temps stayed within 160-190 (using a scangauge). Did not monitor torque converter temps. I got 300 miles per fill-up (87 regular, 10% ethanol, 26 gallon tank), which is pretty good for me. Also used s4 and tow/haul for the steeper inclines (worked out amazingly).

    Prior to pinning, transmission temps would usually go no lower than 190-200 and depending on elevation, driving up hills, etc it would hit 220 easily. Same variables as earlier.

    Only thing I noticed was the ac didn’t blow as cold as usual but I’ll take mild ambient temperature in the cab over lower transmission temps and decent gas mileage any day.

    Is there anything wrong with running the thermostat pinned opened full time in hotter weather?
