engine and Auto trans cooling question

[octanejunkie]

Well drove around this weekend towing a trailer and in the dezert for well over 400 miles and never saw a temp above 193 when towing up a grade. Never saw above 188 even in sand washes

Let it idle for like 20 mins and saw 202 on the scan gauge.

Not sure if these numbers are normal but I was semi happy. I don’t like seeing a digital number persay and the factory gauge stayed in the middle.

I need to put a dan shroud on it and I think it would cool
Even better so that’s in plan.

Are these coolant temps you're quoting or transmission temps?

The stock temperature gauge on the Toyota is not very sensitive and you'll probably never see it move unless you're overheating.

I use Torque Pro to monitor my Temps and never really see coolant temperatures above 200 and since installing my transmission cooler I've rarely seen transmission temperatures above 190

They were coolant temps. I have not installed a trans temp sensor yet since my 96 is not able to be read with the scan gauge

Gotcha, coolant temp is totally unrelated to trans temp, in my experience but it's a good thing to keep an eye on; trans temp however is key

I need to get a trans temp sensor and gauge and maybe even an auxiliary cooler in my truck soon I think. Especially since I won’t be re gearing really soon and the driving I do in my 4Runner is traffic stop and go and also a lot of silt and sand.

Trans gauge and sensor, and a fan shroud are the to dos next but so far happy with the temps the smaller radiator provides coolant temp wise.

I installed a glowshift transmission temp gauge on my 97 and it works great. Think it was about 55 bucks. Only took about an hour to install and I tapped into the soft line that sends the hot tranny fluid into the radiator. I figured this would be the "hottest" the tranny fluid would ever be.

When towing my boat in the summer, I've seen it as high as 200 degrees which is still just fine. I also run full synthetic tranny fluid (Valvoline max life).
