    Hi there,

    NOT to make another Tundra missing the trans cooler thread.... I got my new Tundra with the notion that I will keep it a very long time and go on many adventures... So at the very least I'd like to actively monitor my trans temps since that DOES seem to be the weakest link if there ever was one now.

    I was about to purchase a Scanguage II but saw that others had issues with adding some kind of codes or junk? I'd really like something easy that I can use just anytime I feel the need. My only hitch with using my phone would be that on our travels I use it with apple carplay for maps. I dunno exactly how I would monitor temps in those situations.

    Thanks!

    I choose not to worry about it. I’ve got more than enough things to fret over. If I have the overtemp light coming on I’ll revisit this. Until/unless that happens I’ll just continue to drive the shit out of it.

    Same for me, though my use case is a bit different. I don't tow all the time; and even if I did, most of it would be with my 14' trailer. When I purchased my Tundra, my towing requirements were literally that I be able to tow what I could before (a 20' or so camper, and my 14' trailer) a few times a year easier than my '13 F150 could.

    This'll do that easily. With that usage I SERIOUSLY doubt I'll ever get close to having any issues; but if I ever get any overtemp light come on, or I start towing more, I'll install the aftermarket cooler.

    ScangaugeII is the easiest method of monitoring your transmission fluid temperatures. I own an UltraGauge Blue to avoid the cord. That also ties up my iphone, but I can get by using one or the other. An adapter cord is helpful to keep your iphone charged if you use it to monitor temps.

    Minor hack skills are required to input the proprietary codes into ScangaugeII properly. Not difficult, just go slow and proof read thoroughly. All the other alternate methods will require the same or greater hack skills. At least with ScangaugeII, you do not have to setup the display format, which is much more complicated than the simple data codes.

    Face the facts, Toyota never intended owners to read their transmission fluid temps directly.

    A great volume of information pro/con on all monitoring methods exists in the forum archives. Use search.

    I use it with the OBD Fusion app on my iPhone. Simple plug and play.

    You can buy the Toyota pack in the Fusion app for 9.99 and get a ton of gauges to monitor. I haven’t done that yet, as I can monitor the trans pan and TC temps without it.

    Scanguage works just fine, also used it for the transmission service to check the level at the temp per Toyota's service manual.
