Any instructions on how to install this gear?

Months ago, I had tranny problems after a fluid and pan change. Everything by the book, including the level check. I was frustrated, thinking it was the fluid (redline d6) and was going to order zf.

Then I saw threads on powerstrokes and jag forums on how the level is so sensitive and it's a pain to get it perfect. So i decided to put a slight tilt and added another quart, which they calculated to be less than 1/4 inch of level anyway! No problems since then and great shifting with redline d6!

A big thumbs down to not having a dipstick. Filling by a hole might work consistently for manuals, but for autos it's a bad idea. And what gives with no level sensor at least? Poor op driving around with low fluid durr to a leak and never would have known unless the trans started acting up!
