2004 Nissan Xterra automatic transmission. Was trying to install an Autometer Trans Temp into the fluid pressure test port... realized that OE test port plug bolt is M10 x 0.9 thread?? Never even heard of that pitch for an M10... usually extra fine is M10x1.0
My trans temp sending unit is 1/8 inch NTP, was able to get an M10x1.0 adaptor, which I was certain was going to work, but alas. Any ideas??
I also tried to thread a new M10x1.0 bolt in and it didn't want to go in at all. So yes, definitely 0.9!
