H3 Check transmission fluid condition

[altide8]

What conditions do you guys check your transmission fluid in? I assume after the engine is warm but I’ve read mixed reviews about checking it in park. Cycling through p-r-d. Curious to hear what you guys have to say. I had my trans rebuilt 6 months ago. Think it could be leaking

Check it while its in gear. That will give you the true level. Your torque converter take a good bit of fluid to function.

Owner's manual has the directions. Pretty sure it's it needs to be at operating temperature and parked on a level surface, cycle through all the gears, stopping at each one for a few seconds or so, then back to park, then check while it is still running.

As I recall, warmed up and in gear is ideal. Putting it in Park is more of a manufacturer safety requirement vs. the best way to check levels. But either one should be sufficient, and you can do it by yourself if it is in Park.

In PARK, my tranny dipstick is always in the 'cold marking on the dipstick'---Even when hot?????

Fluid should be red...not maroon or milky. Also take a sniff of it...it should not smell burnt.
Hot tranny, level ground, in park.
