I am going to install a trans temp gauge using the trans cooler line "T" option for installing the sender unit in my 1995 cherokee 4.0 ho. does anyone know what size fitting will be needed? I have searched and found answers of 3/8, and 5/16 does anyone know which one it is? TIA

Pretty sure it's 3/8" however, best way to tell is measure (caliper) or see which size brass feral (5/16" or 3/8") slips over the metal tranny fluid line with the suggest fit.
