I want one for my 81 300D as I am about to pull a small camping trailer. Any links to part and info about installation would be great. I searched here and googled and did not find anyithing. Tomorrow i will call dealer and see. Did not find one on fast lane.

thanks

Try this remote transmission filter setup made by B&M. It has provision for a temp sender. http://www.eurekaboy.com/f250/transend.htm

How about drilling a hole in the pan or finding a test port to stick it in?

Looks nice. THanks. Adding a transmission cooler may be just as easy and cheaper than that perhaps. I called service department at dealer. They dont know of an transmission temp senders and suggested just add a cooler as the one on the bottom of radiator is not that great. I saw one at Advance for 25.00 or so. So I am kind of leaning that way now. I was hoping there would be a simple place to just screw in a temp sensor on tranny. Seems simple enough of a thing to do. But I really dont know.

thanks

How about talking to your dealership MECHANICS. They might know. Also, they could tell you where they are sending the tranny for a rebuild and those people might know.

Did call dealer service. see prev post. They may have crossed. Great idea about asking where they get their tranny's serviced. thanks.

I'm back to liking the gauge idea. I think its a must if you are going to experiment with working out the tranny. I found this B&M one that comes with unit that Ts into line. Sounds easy enough. http://www.jegs.com/webapp/wcs/stores/servlet/CategoryDisplay?catalogId=10002&storeId=10001&categoryId=17705&parentCategoryId=10535&langId=-1

Now, what is that operating range on an W123 81 300D tranny? Unfortuneately the Service manual CDS from dealer dont have transmission data

thanks

In the Jegs one, 220 is the yellow zone. I'd say it is about the same for a 4R100 tranny which is what the 3/4 or 1 ton trucks use too.

However, I don't trust it if you get the reading at the cooler. IMO, it is irrelavant after having cooled off some. I want to know what the pan temp is.

You are my favorite person for the day. I was ready to settle on that Jegs one which is inferior for several reasons. Now I searched again (So tired of internet ) Take a look at this http://neptune.spacebears.com/cars/stories/trgauge.html

I'm going to call around tomorrow and see what tranny shops are using. It seems like a pretty generic sytem would work. Our pans look similar to the mustangs in that link dont they? I've never taken mine off yet.

I'll post back.
