[W126 Coupe] transmission problem

[Jonathan]

40K is about 20K overdue.  Fluid and filters are Cheap insurance in 
relation to what a new transmission costs.  I'm assuming, but you did 
not mention checking that the level was indeed correct and that you 
checked it after @ least 10-15 miles of driving on a level surface? 

It could be a low level issue, an internal leak or a front pump issue.
