Accutemp Transmission Temperature Adapter for 1/2" Lines
The Accutemp Trans Temp Adapter was developed to allow for accurate reading of your transmission fluid temperature without the hassle of tapping into the cooler line. It takes merely a few minutes to install. It simply attaches to the cooler line with the supplied hose clamp and the sender gets installed without the need of Teflon tape or other thread sealants.
The Accutemp works by monitoring the radiated heat in the cooler line. Our tests have showed that it reads approximately 5 degrees cooler at 200°F, compared to monitoring the fluid temperature with the sender in the cooler line.
Because it attaches to your OEM cooler line, it will not void your factory warranty. This is a great alternative to either drilling and tapping your pan or cutting the hot line to put in a sender manifold. It is also a lot cheaper than purchasing an aftermarket pan just so you can read transmission temperature.
These will work on any 1/2" hard line found on the 03-07 5.9L and 07.5-09 6.7L Dodge Cummins.
