Some years do not have the bolt on the dipstick near the oring area.

They only use a bracket to the back of the bellhousing.

I have fixed this problem a couple of times by using a new O ring and loosen the bracket bolt. Put a screwdriver in the tube and give it a couple of light taps to seat the tube a little deeper in the trans.

But,
more than once I found the sector shaft seal was leaking and the fluid ran to the corner near the dipstick and dripped throwing me off track..Had to change the sector shaft seal..
