3 speed auto trans temp gauge connection

ok,ive read many and all threads i could find and most hook the tranny temp sensor into a t fitting..
ive read there are 2-3 servo service ports on the pass side to install my new auto meter sensor into my 3 speed auto but havent read where anyone has actually used the service ports?
i have no problem welding a bung in the new deep pan i got,,but shouldnt the service port be a easyer better place to install it..? im ready to do this but waiting on the right decision for placement..i wanna do the best thing and only one time would be nice opinions welcome

I "used" to have mine t-d in off the cooler return but now it will have to go to a bung in the pan. If you want a flat skid... you won't have any room to do what you want with that sensor which is why mine will be getting relocated.

I have a deep pan also but wanted to see "total high temperature" in the transmission system fluid.
To read that you need to be reading the torque converter temperature.
The only practical way of doing that is by measuring the fluid temperature in the output line from the transmission, I use a "T" fitting for the temperature sending unit in the transmission output line.
Yes, this works well for me...

....and again...what are you going to do with that total high temperature reading? Stop and let your transmission cool off or maybe pull over and immediately add another cooler? But you go girl

We have the four speed but it still applies...

Two sensors, one gauge, and an ON/OFF/ON switch.

"Cool" sensor in the pan via bung.

"Hot" sensor on the line that outputs from the trans to the cooler.

The theory was to see the delta between the two to measure the cooling efficiency and determine if an external cooler was warranted, right-sized, etc.

This is exactly what I have done with my three speed trans.

Why not just add a thermostatic switch to a fan driven cooler and be done with it? That way you have it if you need it instead of all that fiddle farting around? But for some people... like shift levers...lots of switches and guages sure are cool

As for my original point.... running a flat skid sucks up alot of real estate under the tub. Tranny lines, sensor t's and the like don't have alot of living space around the front DS CV. I elected to 86 my t arrangement and will install an in pan bung so that I reduce any chance of the front DS taking out my cooler lines if it decides to implod itself.

my homemade skid is very bullet proof so it will stay for a long while with a 2 inch hang down that blends in nice"to me"with the arms and setup im building..the bung is easy if its the best thing to do,,thanks robert

thanks k.head..i read the same elsewhere but need a lil push from time to time..on my 32rh"97 tj 4.0 3 speed" do you know if its the lower line i need to tap into or the upper..ive herd the lower but you know how that goes lol..kinda like assume,hahaha

thanks for all the replys guys"or trash talk"hehe...im trolling away till i get to the bottom of this

It's the more forward line on the transmission, IIRC?...

thanks..i will double check first

i also read somewhere that i can take this line lose and crank it up and put in neutral and when 4 quarts come out in a catch pale to stop,add 4 more,then top off..something like that,,,after i change the pan and fluid of course..does this sound correct..
also,thanks for the t.case sight tube idea i while back!

if you scroll down to post #7 here http://www.jeepforum.com/forum/f19/t...estion-499743/ and see the pics of these so called service ports^^^^^^^..sure looks like the pressure port would be a great place for it? this is why im researching my butt off but not comeing up with anyone thats actually done this and what the outcome was..so its leading me to the t fitting in the line..ive got 2 more days till my new inch lb t.wrench will be here so hopefully i will find out"why not"the service port..

You want to remove the return line for that - the rear one - or do it on the output side of the cooler - to empty the cooler.
