Can anyone tell me where i can install the sending unit for the transmission temp gauge on a 2003 dodge ram hemi. I have read other forums saying to install in test ports, but cant seem to locate them. I purchased a manifold from summit to install in the high pressure line but the fittings where wrong and i had to drill them out, and now the line leaks. Im replacing the line now since i had to cut it to install the manifold. any ideas??

 

You could always weld a bung to the pan.
