What is the difference in a 46re and a 46rh?

The primary difference between the 46RE and 46RH transmissions lies in their transmission control systems. The 46RE is an electronically controlled transmission, utilizing a computer to manage shifting, while the 46RH is cable-operated, relying on mechanical linkage for shifting. This means that the 46RE offers more precise control and adaptability, whereas the 46RH is simpler and may be more reliable in certain off-road or heavy-duty applications. Both transmissions are commonly found in Chrysler trucks and SUVs but are tailored for different driving needs and technologies.
