Where is the best place to put a temp. sender on a 48re trans
I put mine on the passenger side rear of the trans. right above the oil pan(there was a plug in the hole before) and im only reading 165 degrees tops from the gauge? is that right when hauling a 14,000lb trailer with 37" tires?
I don't want drill and tap the pan if i don't have to.

did you use the adapters to space it out, or did you just thread the probe into the hole? I put mine in the hot line that leads to the cooler, you can get a replacement hose from dieselmanor.com

X2 on the replacement hot line from diesel manor. i love mine and havent had any problems with it.

x3, easiest and best way to install since its reading the hot side. Gives a warning of high temps before it actually gets to the damaging point. The cold line from the cooler will give you a lower temp for obvious reasons, and the pan temp is post cooler also.

Yep, the replacement line from Diesel Manor is pretty slick. Just throw the original stock one in your toolbox and then you also have a spare in case it ever did leak.

Dave Goerend gave me a nice little tip for installing the line. He said if you let the truck sit for 24hrs or more then almost all of the fluid will be drained back into the tranny so you won't have to worry about it pouring out all over the place. Worked great for me!

Thanks for the help
I think i might just try the hot return line from dieselmanor.com

Save your money and just buy the 1/2 compression fitting T that they use. You will also need a 1/2 to 1/8 bushing too. If you can put the line on, you can put the fitting in yourself! The only other thing you'll need is a tubing cutter - available for under 5 bucks at HDC or something.

That's another option too. If you've never used compression fittings before though there's a chance you could end up with leaks.

I like the idea of having an unmolested stock line in the toolbox as a spare. I guess you could buy one from the dealer and make your own. That way you would have a spare and if parts are wrong/missing your truck isn't down in the driveway with a cut line.

For me, it was worthwhile just to buy it from DM for a few bucks more.

To answer your question, I only see temps of 160* under normal conditions, and it takes a long time to get there. Towing has always been under 200*.

Accu Temp adapter from Geno's ($32) gives very good readings w/ simple install, no violation of cooling line integrity and cheaper. Mine works quite well, just finished towing 11K rv to Florida and back, 5600 miles and gauge read just where I expected it to, 160 on level freeways and up to 190* on steeper grades. I backed off when temps exceeded 190*.

$11.29 from my local harware store. Done in 25 minutes and no leaks! To each their own. Just my .02 .
