4R100 Cooler Lines
Does anybody know what thread is on the cooler lines where they connect to the transmission?
They are either M16x1.5 or 5/8-18. Either will screw into the fittings on the trans but obviously only one is correct. The hole is too short to use a thread gauge. I lean toward the metric but need to know for sure.
