[W126 Coupe] transmission problem

[Jonathan]

Hello Gordon,

I would pull the connection to your kick down switch for starters.  I'll 
assume you have checked and corrected your transmission fluid level if 
necessary. 

You could try disconnecting the FGS worst case. 

Worst case I would think you have an internal leak allowing transmission 
pressure to drop as it gets warm.
