Mishimoto transmission thermostat- preliminary review

[GUZ]

So I have recently installed the Mishimoto with good results. Usually stays 155 170 degrees which seems ideal. I just took 120 mile trip in mid 40’s weather and averaged 65 mph or so (traffic). Around 80 miles In I noticed the trans temp was @ 104 and got as low as 100 degrees before climbing slightly when I came into a town and had a few stoplights. That seems pretty low - almost like the bypass was installed but it definitely has the thermostat in there. Wondering if that seems odd to you guys that have been running it for a while…..

That does seem oddly low if it has the thermostat installed

Especially so as I took a 60 mile trip with only slightly higher speeds and same temps and stayed 160 ish for most of the trip. I will have to monitor in the way back Sunday. I suppose the thermostat could have failed but that seems unlikely inside of 3 weeks lol

Even with a straight bypass I saw temps higher than that. Typically would settle in around 130-140 on a long enough trip, but took an age to get there.

Temps with the Mishimoto have always been pretty consistent in the range you reported (155-170).
