Default Re: Any tips on tranny fluid change?
IR guns do not work well on metal, try to measure a shiney metallic surface to prove this. I spray paint a spot to sense, to get the temperature correctly. Barring that thought, I use a spot of masking tape to provide a reliable black body like surface to measure/detect.

Shiney surfaces have bad emissivities and give wildly variable readings. FYI. The temperature reading is also 'the average' of the surface so dont try to sense a 1/4 spot, their focus is too diffuse for that precision.

Chillin, WOODY
