Don't know what ECM mask trans yet, think dyeager has a few, me too...

I keep telling you guys I'm not good with math! Unless it's a wrench! Got my 8ths and 16th with 4th all mixed up...

The three wire coolant sensor I have 5/8 inch in thread grooves. Is it metric 16mm? The small 2 wire I think is a gauge as the other one just mounted in kids truck was bigger, it is 7/16 or 11mm.
