[W126 Coupe] SEC engine/transmission question

[Jonathan]

Josh,

Interesting...typically they don't fight this much...you may try a 
liberal application of a silicone based lube as that tends to help @ 
times.. 

I've had TC'ers be a bit reluctant and take maybe 3-5 minutes to get 
them to seat but nothing beyond that.  I'd say just keep trying whilst 
wiggling/jiggling/spinning the TC around while twisting the tail shaft 
back and forth.


Best of Luck!!!
