Tranny Temp Sensor

From : travis wootton

Q: id 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. im 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 id be intersted in trying. anyone know if theres a similar test port on the 545rfe if so where is it located id also like to hear other thoughts on the tranny gauge installation. thanks gang. .

located id also like to hear other thoughts on the tranny gauge installation. thanks gang. the cooler line is the best place for it - its the hottest point it gets full flow all the time and it doesnt 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. .
