Automatic transmission temperature sensor the master debate...

-
Are there not available capillary type gauges. These don't use a wire
But a type of tube.
Yes I'm sure I'm going to end up with something on the exit tube close to the transmission. I'll probably bend my own tubes and flare my own fittings..

Not sure I am following you. I doubt that you could make your own
Capillary tube. These come already installed on the gauge and have a fluid in the tube. The heat expands the fluid and pressurizes the gauge to indicate temperature.
 
Likely if you have to ask it's too much LOL either way or I don't want some thing with a wire on the end of it...
You seemed unsatisfied with putting a sensor in the pan. Just trying to give you other options. Just tape a fuckin thermometer to the bottom of the pan.

"Fuickin"... LOL.. you came up with a number of good ideas I've used but not every one of them is a masterpiece...
Because I'm not following along with the thermostat in the dipstick idea doesn't mean it's not a good one and all, it's just not for me... getting hot headed because someone isn't using your idea..:realcrazy:...

I thought about it from the oil dipstick heater I got for a customer once. I wondered if anyone made a temp probe for a transmission and damned if they don't. But it could be used for anything. Oil, transmission, coolant, up your ***......you know, whatever. lol I'm not hot headed one bit. Just throwin ideas out.

Maybe if you put the probe deep enough up your *** you can tell how hot your head is lol...:thumbsup:...
 
I just see a wire coming out of the top of the dipstick and now it's got to be long enough and slack enough for you to pull the dipstick out and then where does all this slack wire go? I'm just thinking it's going to be too hassle and not look as clean as I would like it to...
 
Anyways thanks for everyone who contributed ideas and experience...
Now that I don't want to follow triple R's idea it's gone completely sideways...
Anyways I'll probably just put something on the tube coming out of the transmission to the cooler...
 
I wonder if they have a dual sensor setup? I know like an AF gauge you can get both readings stacked up on one gauge...

I bought my 9.5" converter from PTC and specifically asked them if I needed a cooler. They recommend a cooler on all street cars running their converter.


I didn’t say to not run a cooler. I said don’t run the fluid through the radiator cooler before an external cooler. Skip the radiator. Did PTC tell you to run the fluid through the radiator first?
 
Years ago i parted out an rv that had an aftermarket temp guage and a probe deal that went down in the dipstick tube. Probably made in the late seventys. It was electric, no idea how accurate it was. I thought it was pretty cool and kept it, but ive since then lost it of course.
 
Metric, Imperial, Kelvin.....it would show the delta of the 2. Would need the proper sender and possible weird aircraft voltage. You dont want your trans to run too cold as it will wear faster and the shifts will be inconsistant for a racer. I suppose where you run may be a factor...cold climates, cool the trans and then pipe it through the static temperature of the radiator. Sending very hot trans fluid straight to the rad tank may not help your temperature bottom line let the cooler take the edge off it before it hits the rad. Here's a more common auto app

Awesome!!.. out of stock:(..

I misread your post. Thanks for clarifying. You bring up a great point. Now I'm wondering about the pros and cons of running it through the radiator also.
 
You all can debate the merits of where to install a temperature sensor on the transmission, what is best or what temp reading is important to you, before or after cooling etc but from what information I gathered about how the factory did it (on trucks with that option for example) the sensor was installed in the rear servo pressure test port. That’s what I discovered in my research on where to install, and it couldn’t have been easier. The Stewart Warner electric gauge I’m using works. YMMV
