Hi all, I’m new to the forums. I searched to see if my question had been asked before starting a new thread, but I’ve had no luck so far. I’ve got an 06 Ram 1500 SLT 5.7 with the 545RFE. I’m wanting to install a transmission temperature gauge but all the kits and parts I can find are specified for the Cummins so I just wanted to double check something. I know I need to install a T fitting on the tranny oil cooler line from the tranny to the cooler but I can’t find specs on what the outside diameter of the line are. I just want to make sure that the T fitting I’ll be ordering will fit before I pull the line and cut it. I’ve asked the dealer and they have no clue and said they have no way of finding out, so any help or insight that anyone can provide is greatly appreciated.
