Trans temp sender location?

[O's Fan Rich]

Where is the best place to install the sender for a tranny temp guage?
I was considering using a brass block and passing the line from the trans into the cooler through it and insatlling the sender in the block.
Or is there a pan with a bung already installed to accept one?
Let me know what you did, please.

Rich, your idea is an excellent one. Installing the sender in the line from the transmission to the cooler will give you the hottest readings.

BTW, AutoMeter sells a "transmission temperature manifold" (http://www.autometer.com/cat_accessoriesdetail.aspx?vid =169) specifically for this purpose...I have one on The Blackbird...it comes with all the necessary hardware...the p/n is 2287, available from Jeg's, Summit, and many local speed shops.

Rich,

That's what i did with that very same "manifold" part, cutting and bending the hose going to the cooler. I beleive it's the "hotter" place. With that, i went for a flush of tranny oil , new oil and a deep PA Automatics deep pan for an extra 2 quarts capacity.

I have one installed .But i dont know how its installed:dunno::D

That's how I'm going to install mine....

So, using that AM part, it looks like it comes with two compression fiitings and you splice into the outgoing hard line to install it, correct?
Why not up at the radiator where the tube becomes hose, and splice into the hose?
And, if I may, which line is the outty? Top or bottom?

You could put the manifold there but you'll need new fittings mostlikely barbed then you'll need hose clamps....

Start your car and hold both lines. The hotter one is from the tranny to the cooler.

No gain without the pain...eh?

[fastblackmerc]

you got it!!

Why not up at the radiator where the tube becomes hose, and splice into the hose?You can do it that way, too. Lidio's tech installed mine, and I believe he cut out the hard-line/rubber hose interface and hooked the manifold inlet to the hard line with a compression fitting, then used a barb fitting to hook the rubber line to the manifold outlet.
And, if I may, which line is the outty? Top or bottom?The service manual says the top connection at the transmission is the output to the cooler, which becomes the bottom hose where the lines go around the radiator on their way to the cooler. Remember, the sender has to be vertical and go into the manifold from the bottom.

One thing y'all should keep in mind, is that the closer to the torque converter that you sample temp, your gauge will be the busiest.

Temps will spike more often and to higher temps, and the gauge will be very active. This sample location will not deliver a "normal operating temp", because temps will not be stable. They will spike often, and over 200 degrees.

I prefer a pan mounted sensor, or. taking a sample temp from the return line from the cooler. Knowing what the overall and uniform fluid temps are tells me more than a temp reading full of spikes from a WOT run down the on-ramp.

Neither locations are wrong, it's your choice. But, I find overall temps to be more informative than temps coming out of the converter. If my tranny is averaging 170 degrees, all is well. If it's averaging 200 degrees, all is not well, and you can't see average when it's filled with spikes...IMHO.

Just my .02C, carry on gents.

I really went crazy on my transmission temp gauge install:

I cut the flare fittings off of BOTH hard lines where they transition to rubber hoses.

Next I installed TWO Autometer manifold blocks each with its' own temperature sending unit.

I then used the compression fittings on the hard lines and barbed fittings on the rubber lines to connect both manifolds.

I then wired each sender through a switch BEFORE the transmission temp gauge.

Now I can 'toggle' the switch to see the outgoing-HOT temperature AND then the returning-Cool temperature.

I also installed a B&M fan assisted transmission cooler after the OEM cooler.

The transmission temperature NEVER goes over 180 degrees...even after a 1/4 mile run.

Usually see a 20-40 degree difference between the outgoing and incoming lines.

Sweet!
Didn't wanna go with two guages?

I believe he uses one gauge and the switch to select between the 2 sending units.

Understood.
I was curious if he'd thought about using 2.

[Joe Walsh]

Nope, I already have 7 gauges * mounted in my Marauder....so there was no room for two transmission temperature gauges.

*Trans temp. & Ammeter in OEM gauge holes,
Oil temp. & Oil pressure in twin A-pillar pod,
Boost/Vacuum & Fuel pressure in Mustang twin dash pod,
Water temp. in F150 steering column pod. (fits MM steering column perfectly and the OEM temp gauge still functions because I used a new sender for the Autometer gauge.)
I still have a single A-pillar pod to add for intercooler temperature gauge when I add a S/C.

.

What year F150 is that Joe?

[Joe Walsh]

I can't find the Autometer box in my garage...I'll see if I can find my SUMMIT Racing invoice for the model number...
I THINK that it was for the last gen F150 NOT the new style F150.

Thanks Joe.
