[Mgs] Overdrive does not work when it is hot.

[Andrew B. Lundgren]

  When my OD gets hot it won't engage, it will actually disengage once 
it gets too hot.

I had the entire OD and transmission gone though before I installed it 
at a local MG specialist that was probably 5 years ago.  Since then I 
have put less then a few thousand miles on the car.

I don't want to buy a new solenoid if that can't be the problem...  I 
have changed the oil in it a few times hoping that might be it.

Thanks!
