Trans temp sender install location - 2012 JK Auto
I'm looking for places to install the sending unit of an AutoMeter Transmission Temp gauge on a 2012 JKU with auto transmission. As you know, there isn't a drain plug on the the mercedes NAG1/Mopar WA580 transmission, and currently, there aren't any after market replacement pans that fit (there is the cross brace and exhaust under the pan) PML is designing one to fit with a boss for a temp sensor, but it will be a few months.
I don't want to pull the pan and braise a boss in the stock pan, so I'm looking for options.
1) There is are 2 threaded fittings where the steel fluid lines (out and return) attach to the transmission and transmission pan. I thought I could get some pipe fittings and install a T at the connection point. Not sure what thread/size those connectors are, and if the lines have enough flex in them for this to work.
2) Splice into the rubber section of one of the lines up by the radiator, install a T with the sender.
3) Cut one of the steel lines, flare the ends and install a T for the sender.
