Any reason I can't use a stock water temp gauge for a trans temp gauge? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Can I use a factory water gauge wired the same way as the water gauge but put a oil sending unit in the transmission and use it to gauge oil temperature? I would have to get a sending unit for oil and not water temp I suppose. What should a th400 run for temp? Is this gauge going to be in the correct temp range for the tranny? Any insight on what sending unit that would be the correct ohms would be appreciated. The gauge is from a square body truck. Thanks in advance.
