Set up trans to only shift down to 2nd

[BathCity]

Is there a way to set up the current trans on my 300CD Turbo so it won't shift down into 1st, just down to 2nd. All the remaining gears work in the trans, it's just that I have to rev the engine to 2k rpm to get the car to start moving, then feather the throttle until the trans shifts to second, then she moves just fine.
I have been unemployed since the end of July and really can't afford to have the trans rebuilt right now.
