AW55 pressure tap thread size?

I wish to datalog some pressures on the transmission. But no information out there on what the thread size is for the pressure taps/ports.

I have to buy the correct thread size pressure transducers. Unfortunately the ATSG document doesn't mention this. If no one knows, I will have to bust one out of the transmission to verify.

Based on what I left attached to the pressure gauge hose, M8 X 1 Taper for the pressure tap ports and as shown in the photo I needed some 1/4" npt elbows and a short extension for one of the ports due to limit space.

Thanks for this information. I will try to get some of these and I will need to monitor all of them at the same time.

I have the same OTC set.
