Who has a temp gauge on a 48RE Trans

[Polaraco]

03 3500, electric cooling fans, new trans 1 year ago. Ambient temps 55 to 60*

I recently put a temp gauge on my trans. After running around most of the day, local and short interstate, the most I've seen 139*. 120* on the highway. If this is a true reading, I am thrilled! Means the cooling system is in great shape and the trans has no slippage at all. I just don't know if it's true or not.

What are you seeing?

Side bar, I'm used to seeing 190 210 on the old 727's. The 48 is a beefed up 727

Do you just have regular tranny Pan ?
Do you have Mag Hytec Double Deep tranny Pan ?
If just regular Pan and your pulling loads and if it is hot out sounds pretty close to normal bud !

Never thought about the pan. Sorry 'bout that. It's a stock pan with a port I added.

The Temps sound almost too cold. I just wanted to find out if my gauge was off. LOL Thanks

This is far from scientific .. my cousin tested the temp of his pan from a ditigal thermometer on the outside of the pan (material used as an insulation over it next to the pan) verses the reading from your instrument .. pre startup.. The temp was within a couple degrees. When he returned home, and it was hot, he did it again and it was reading withhin a couple degrees verses his instrument panel.

As said, NOT SCIENTIFIC, but allowed him to see his was close. If you want actual reading verification, your gonna have to pull and have it professional check, or replace it with another to verify. Or find a long temp probe to get into the liquid. But as you know, lots of extra work, messy and cost.

Thanks Jim. Actually I already considered that. Even dug out the thermometer. But I decided to ask before I get dirty. LOL I can tell if it's kinda/sorta close to accurate by just touch.
This was so much easier. LOL Give a lazy man a job and he'll find the easiest way of doing it. hehehe

If it's running in this range, I am thrilled. Heat kills. It shows no slippage in the converter on the highway and no slippage in town. The engine is transmitting some of that temp.

What gauges are you running?

I just dealt with this exact thing on my 09 68RFE. Mag Hytec pan under 60 degrees the needle never budged. Especially in winter

I moved the sender to the hot line with a clipsense adapter. Still have to see temps 60+ before it really starts to move and takes about 45 minutes to an hour of driving

All the extra fluid I'm running my temps stay very low. During winter they don't get anywhere near the 100° minimum of my gauge

ISSPRO gauges

I'd suggest plugging the pan. And running an adapter on the hot line as close to the trans as possible. Mine is about 4 inches that's as close as it could get
Also keeps chances of contamination away not having it in the fluid

Here's what I'm running

Comes with a standard foam insulation to wrap it. There's a couple other styles on the market. Auto Meter makes one to

I experienced the same on my 08. I can easily make one of those brackets. Good idea. Thanks!

Originally that's what I was going to do. Then it dawned on me in installed a drain in my pan and it would go right in. Thought about it being a standard depth pan

Ya they are very simple. Theirs just has a few slots and taps so it can be mounted on different sized lines
Auto Meters is a bullet shape that you insert the sender. Not sure if that design would be better or not

Mine was free from ISSPRO to try and figure out why I wasn't getting readings

The only problem I have it's a bit pricey. I can dupe that in short order. I have all the tools and aluminum here to do it too. I have a 20 ton brake for that heavy stuff too. Is that the one you used for our large lines? I forget what size they are . Looks larger than 3/8. Thanks for the lead!
