Re-Filling the 722.6 Transmission

I understand the 722.6 trans is very sensitive to fluid level.

Can any one tell me what that means. I believe Im overfilled and the trans neutrals out after getting up to about 20 MPH. This is in a 1996 SL600

How do I use the special dipstick tool. I received no directions with mine. The picture is as far down as it will go. Does that look right. If I put it in as far down as it will go as shown in the picture and the fluid level is above the high temp highest mark after limping it around the block one time.

This transmission was completely drained including the TC. There are approximately 9.25 new qts of fluid in it and it appears to be about 3/4" over filled. Might this explain a neutral out condition.
