Re: Twin Ultramatic Shifting

someone asked: "Can someone tell me why my '56 400 pushbutton twin ultramatic has a tendency NOT to shift out of 1st gear when I'm in "Drive"? It shifts fine when I'm in "High"?"

Does this happen all the time or ONLY directly after pushing the D button???

My 56 Exec does the same thing once in a while. Especialy going from P to D or R to D.

Try this: push the N button before pushing the D button. Give it about 3 to 5 seconds between button pushes.
