I have an idea to install two temperature sensors, on two oil lines what are coming out from the transmission (Sterling 827). One sensor for the oil coming out of the transmission, and the other for the oil return line. I just don't know what thermometer should i use? what temperature range? i found such 32 ~ 248=B0 F dual thermometer:
what do you think? is it enough? or maybe there is some better thermometer, any advice appreciated.
A thermometer needs to read and display information. It looks like that analog thermometer with digital display will do just that. I would find an analog meter with a mechanical pointer to be a lot easier to read. Especially during the day when light can wash out those little numbers completely.
I have to ask why you need to monitor both sides on an automatic transmission. Indeed I wonder what purpose a transmission temperature display will do on a passenger car with an accura transmission. Are you towing a heavy trailer for long distances?
thanks for your reply. I don't tow, mainly city driving, but i read that even during normal driving transmission fluid gets to hot, and its better if the fluid is cooler, should around 170F. I'm planning to install an external tranny cooler too, so it would cool down the fluid after it exits the radiator. And i thought it would be good to know how does it perform, what is the temperature drop between hot oil coming out of the transmission and cooled down oil entering the transmission. I wouldn't install this gauge permanently on the dash, i'd keep it in a glove box, and check the temperature of the fluid if needed. If its still to high i'd add a little fan to the cooler then.
Why not use a transmission temperature gauge, something along the lines of this :
And you only need one gauge, not two. There's no reason (other than curiousity) to measure the temperature drop across the cooler.
Isn't this a 20 year old car roughly? If so I would think that transmission and other overheating problems would have surfaced on this car as well as on the parent car the Accura.
Yes, transmission fluid gets hot, as does engine oil in normal driving. But if you buy good brand fluids and keep them changed I don't know if there is really a problem to solve by adding a transmission cooler and temperature gauge. Most car manufacturers including Honda design engines and transmissions with cooling in mind.
I understand the Sterling has a less than sterling reputation for quality but I don't think that extends to the drivetrain does it?
Sure, but what can you do about it?
If you do this, there is no need to measure the temperature on an ongoing basis, is there?
Have you considered just installing a manual transmission and being done with it? This all seems very silly to me.

the car is '94 but i'm trying to keep in a good condition, new radiator, new thermostat, new coolant. Engine temperature is very stable, i have no concerns at all. But i haven't replaced the transmission fluid yet, previous owner replaced it with some dexron III when the car had 160kkm, now its
213kkm and its time for new fluid. ATF-Z1 is not an > :Thanks for the link! the gauge seems to be cool and its temperature range is very same as that LCD thermometer i posted, so i guess mine will do the job too.
Well i'll post the results when i install it.
ow the link doesnt work , here it is:
No, I still think you are out of your mind. If you are worried, either you can use a high temperature fluid or you can use a cheaper fluid and change it more often.
There's no reason to flush the whole thing. Just do a change. It'll leave some fluid behind. That's okay. Do it again in another 30,000 miles.
Sure, a transmission fluid cooler OR using the higher grade fluid will allow you to extend your service interval. But it's sure an expensive way of doing it. Use the cheap stuff and change it often.
