[W126 Coupe] SEC engine/transmission question

[Jonathan Hodgman]

I tilt the trans upwards in a 5 gallon bucket...put the TC in and turn the
tail shaft..  It will Really seat/settle in (usually 3 steps of engagement)
once you have it settled.  There is a plastic plug that should be in the
bottom of the trans, when that clears the TC you know you have it in all the
way.

The last drop/step can be a bit difficult @ times..
