How hard is it to hook up a tranny temp gauge on a 99 CTD? And where at do you hook it up? And is it necessary if your not planning on doing any towing, just putting some stuff in the back every now and then.. I will be driving about 50 miles a day to & from work and up & down hills?

Shovelhead

If you're not adding mods, and not towing heavy, it might not be worth it.

I used the '95 (i think) trans line with the test port in it as a replacement line when I did my install. Part number 05011244AA

I did the same thing as shovelhead. Makes for a very nice, clean install. Well, clean after you clean up the tranny fluid off of everything. I agree though, if your not gonna be towing anything and don't plan on adding anything more than maybe an Edge ez or something similar, then I wouldn't worry about it.

Same install as Shovelhead as well.

I don't tow anything, and rarely have the bed full either.

I do however offroad a lot, which is murder on a transmission, I've seen temps in the red zone quite often.

With the guage, I know when I need to take a break and put it in neutral to cool things off.
(Dodge trannies don't circulate the fluid in park)

Is there anywhere else to put it on the tranny on the 99's...If not where can you purchase a line with a test post?? Because later on I'm going to be adding more power with and edge and i figure that it wouldn't hurt to go with it now...

You get the line with the test port from Dodge, part number in Shovelheads post.

I hooked mine up with a sensor epoxed to the outside of the pan . It came with the sensor. I can get details if you are interested.

Shovelhead

Pan temps are the lowest in the system.
The replacement line checks temps at the hottest point, in the line carrying fluid from the trans heading for the heat exchanger.

I was slow to accept the need for reading Tranny fluid temp at the oil cooler line...but once I made the change, the differences in temp readings was amazing. Probe in the pan is better than nothing but gives a delayed reading and an average reading...not the best, especially if adding HP to a stock trans!
Lots of good info available, with pictures, if you do a search.

If you don't want to buy the line go to Infidels picture gallery- he has a great alternative.

Not me, I use the '95 lines also.
Know what you're talking about though, there is a picture in one of the moderators here gallery of a setup using a compression tee in the line instead of a new line. Much cheaper but I personally don't like the idea of introducing any more potential leak points, these trannies are just too expensive.

That truck/picture belongs to Dennis "RattlinRam" Tway.

Sorry Infidel,

Look I was giving you more credit than you deserve!!

BigBlue

That's the 95 line.

For all you with autos. What temps are you seeing in stop and go traffic? To many stop and goes for me in town I can quickly reach 250 in the hot line. With my foot on the brake at a stop light I can watch the gauge climb quick until I start moveing again, then it climbs slower.

Thanks Mooseman
