Which line is the hot side going to the cooler. Got the gauge yesterday but still have to locate a tee so I can install it. Also. Shouldn't the trans lines be steel all the way to cooler. I have rubber n mine and it looks like someone spliced them n

 

Not 100% sure, but I think it's the most forward line. Maybe a search here will elude to this, or Angry Johnny or another member will chime in.

Disconnect the hose end (either side), and have someone crank the engine over in neutral and shut if off fast.. That will give you either suck or blow of the fluid. The fluid blowing towards the cooler would be your "hot" side.

Mine is in my transmission pan.

It's been debated on several occasions as to what is the "best" place to put your trans temp gauge, whether on the pressure side to the cooler or the pan. The "hot' fluid comes out of the trans, but the fluid being recirculated back into the trans (from the pan pickup) is also important, as that's the temp of the fluid being recirculated back into your transmission.

I personally would want to make sure that the fluid being dumped back into the pan is "cool" enough not to smoke out the trans, regardless of what the outgoing temp is, but that's just me. This lets me know the trans cooler up front is doing it's job..

In the pan, it's easy to install. I get to watch fluctuation on really hot days, or when I'm plowing snow, otherwise it hovers about 160*F to 175*F



Would be cool to see someone put it in both locations and determine the differences in temperature.

 

BTW,

A heavy diesel mechanic buddy of mine said to me that if the temp gauge isn't actually in the "flow of the line", then the reading it gives will be skewed / altered due to ambient air cooling around the fitting it's mounted in. So, if you find a "tee", and you put your sending unit sensor in there, see if the tip protrudes into the flow of the head of the tee or not.

 

That's where I put my temp probe, mostly because the pan had a port for it and I was lazy I guess. Those temps are about what I see as well, unless I'm towing or in stop and go traffic.

 

The front line closest to the torque converter is the hot side, it returns at the tailshaft.
I installed mine in a "T" just behind the torque converter on the way to the heat exchanger.

I have a low stall converter and my pump is turned up, under hard acceleration the temps climb rapidly since it is seeing the hot fluid right out of the converter, my transmission man moved it to the pan because I kept questioning him why it climbed so rapidly, so I have two sensors and a switch to select what I want to be seeing. I would like a gauge with dual temps in on unit like the ones used on twin engine aircraft.

I also have the optional heavy duty under bed cooler.

ATF breaks down rapidly around 275*-300

I have no connection with this site, just for the information.

Hey, Jim, curious, cause you and I live in areas with identical temps. At about an 80 degree day, when at a stop light, or stuck in traffic, what are your temps at? When I leave my place, drive into town for about 30 minutes, the temps show about 135-145. The minute I come to a stop, and it lasts more than 3 minutes, my temps will be at 180, which then kicks on my auxiliary cooler fan/coil( like your set up). It'll keep climbing to 185 or so, then hold. During the summer months it'll keep climbing, then I have to put it in Neutral to start lowering the temps.

 

Would oil temp be anything to worry about with a GetRag?

Edwin,
It is much less of a worry with the Getrag.
I over fill with 5 QTs of Mobil 1, and use aluminum PTO cooler covers on mine. I also don't tow much if anything with my 1st gens. That is what my '95 Dually is for.

 

It's the steel line going from the trans to the block mounted heat exchanger.

You could just use an IC (A518) hot line and use the high temp OD cutout switch port for your gauge sender.

270 in the hot line will be around 220 in the pan.

 

Thanks. I e decided to put it n the pan. Got a feeling I'll be changing trans sometime this year

 

I put mine in the Tee for the OD kick out switch.

BTW Jim, I have Westach gauges and the temp is a dual for monitoring two sources. I like it, one hole for two simultaneous readings.

 

Ooo

 

That is one hole or opening in the gauge pod...
