* Increased rotational inertia: 24" rims are much heavier than stock rims, increasing the rotational inertia of the wheels. This puts more stress on the transmission, especially during acceleration, hard braking, and shifting. The transmission has to work harder to overcome this increased inertia.
* Higher RPMs at highway speeds: Larger rims, coupled with the stock gearing, mean the engine will be revving higher at the same road speed. This puts extra strain on the transmission components, increasing wear and tear, and potentially leading to overheating.
* Stress on the drivetrain: The added weight and stress also affect other components of the drivetrain, like the axles, differential, and even the engine, potentially leading to cascading failures. A damaged component in the drivetrain can further damage the transmission.
* Aggressive driving style: Racing inherently involves aggressive acceleration, braking, and shifting. This puts immense stress on the transmission, regardless of the wheel size, but is amplified by the factors mentioned above.
* Stock transmission limitations: The Crown Vic transmission wasn't designed for the stresses of racing or the added weight of 24" rims. It's a relatively robust unit for its intended purpose, but pushing it beyond its limits will inevitably lead to problems.
In short, while the Crown Vic transmission is fairly durable, racing it on 24" rims is a recipe for disaster. The increased stress and strain will significantly shorten its lifespan and likely result in premature failure.
