mine is the three speed auto and it shifts too early making the car lug a lot.
<p>The 1956 automatic transmission (Twin-Ultramatic) is a
TWO speed! It may feel like a 3-speed because the lock-up torque converter feels like a shift when it locks up. Shift out of low is designed to be at lower speed.</p>
<p>In other words, your T-U may be operating normally, you just may not think so because it behaves differently than a modern transmission.</p>
<p>Try starting in "H" position. This eliminates the low-gear start. You should only feel one "shift" which is actually the torque converter locking up.</p>
<p>Also, try starting in "L" position. This holds the transmission in low gear. The one "shift" will again be the T-U torque converter locking up. Once locked up, then shift manually to "D" or "H" and you will feel low gear release (shift).</p>
