This is a problem when converting the '54 rear ends to 3.55:1 using the ring and pinion sets available from Patrick's. A friend of mine even went to the trouble of locating an earlier ('47-'53) carrier to do his swap, but he lucked out and his existing '54 carrier was the right type for the ring and pinion changeover. Fearing the damage and wear that could result from this practice, GM engineers in 1953 provided an automated first-gear start and programmed upshift at up to 42 mph depending on load, and a throttle-controlled kick-down function as well.
