Thread: Can I run w/o trans oil going into radiator???

34_40, I guess that is what you call it. It is a cap-nut over a threaded sleeve with a copper bead on the tubing. I have one on my fuel line where it goes into the pump on the low pressure inlet side and I put the fitting into my vise and got a good tight wrench fit on it. I suppose I could take the trans fluid line out of the car and get it into the vise for a nice tight fit but I would not trust the seal on a situation with two wrenches turning in opposite directions while in the confined space of the engine bay. Tapping the trans pan for the temp sensor seems like a good idea at the moment. I called the "Eat My Shift" guy from whom I bought the 700R4 and he recommended Dextron-3 Mercon or better Royal Purple and he thought the situation would be OK for weekend travels with just the radiator cooler, the Derale pan and a high end fluid but he did highly recommend a temp gauge. The Derale pan is indeed the lowest point under my car and speed bumps may be a problem but it is steel and tough enough to dent rather than crack so I think the extra volume of the fluid and some help from the air tubes will hopefully be adequate for "touring". Henry Rifle's SPDT switch is a good idea and solves the problem of my already crowded array of dash gauges and switches. One question that might occur is whether the 12V analog signal from the water temp sensor is in the same range as a 12V trans fluid sensor using the same gauge?

IC2, thanks for the confirmation on the trans pan mount. I would think that location would actually be more accurate for the temp of the fluid.
