Car Forum / Dodge / Dodge Trucks / February 2006Tranny Temp Sensor
I'd like to add a tranny temp gauge to my 2004 Dodge Ram 1500 (5.7L Hemi w/545RFE trans) to monitor temps while towing my travel trailer. I'm leaning toward installing the sensor in the hot-side cooler line. A buddy has an F-250 that had a test port in the tranny where he installed his sender. This would be an alternative I'd be intersted in trying. Anyone know if there's a similar test port on the 545RFE? If so, where is it located? I'd also like to hear other thoughts on the tranny gauge installation. Thanks gang. > located? I'd also like to hear other thoughts on the tranny gauge > installation. Thanks gang. The cooler line is the best place for it - it's the hottest point, it gets full flow all the time, and it doesn't risk any mechanical interference. The second-best point would be the pan itself - pretty easy to drop the pan and install an 1/8" pipe bushing in the side of the pan - this can also double as a drain plug. Thanks for the info, Tom. >> located? I'd also like to hear other thoughts on the tranny gauge >> installation. Thanks gang.

Thanks gang. http://groups.google.com/group/alt.rv/browse_thread/thread/c79dcd2d0c0e64b9/93f2 ca60db7a61ef?lnk=st&q=Transmission+temperature+gauge&rnum=8&hl=en#93f2ca60db7a61 ef I used the gauge in the above thread and it gives a rise in temp. That is all you need to know. It took me a couple of hours to install. Once installed, I drove 15 or 20 miles to get a base reading from the gauge. When towing, if it goes up 50 degrees, I back off. I've been up and down mountains all over the US, Canada & 14 states in Mexico since installing it. On 1 trip there was a couple with the same model truck with a factory gauge installed and towing a similar trailer & we were getting readings very close. I like my $15 Pyrex kitchen gauge for transmission temp reading!!

This thread gives you the description and model #.

Test ports in the case are possibly the worst place to place a temp sensor, typically there is little or no fluid flow in the chambers where the test ports tap in; the fluid in those chambers is "dead headed". When we had pickup trucks we had tranny temp sensors. It was a helpful tool with the heavy slide-in and the one-ton PSD that toted our KoTR fiver. We didn't put one in the Freightliner because we had a manual with AutoShift. Anyway we now have this giant Chevy motorhome (workhorse 22) with an Allison 5 speed and I've never seen a posting or heard a conversation about putting a tranny temp sensor into a motorhome. Does one need a tranny temp guage on a MH? Does anyone have one on theirs?

If Workhorse doesn't, IMHO they are negligent. Lon My Chevy P/U came with one. You can look at www.jegs.com and they have a B&M temperature guage and sender.
