Common Choices:
* 727 TorqueFlite (Chrysler's 3-speed automatic): This is arguably the most popular choice, especially for street applications. It's strong, relatively simple, and readily available with various aftermarket parts for upgrades. It's a good all-around choice for many applications.
* A727 (Overdrive version of the 727): Offers an overdrive gear for better highway fuel economy compared to a standard 727.
* 904 TorqueFlite (Chrysler's smaller 3-speed automatic): Lighter than the 727, but generally not as durable for high-performance applications. Suitable for less demanding situations.
* A904 (Overdrive version of the 904): Provides better highway mileage than the standard 904.
* 998/999 TorqueFlite (Chrysler's 3-speed automatic): Used in heavier-duty applications like trucks and vans, providing a robust alternative for high-torque situations.
* 4-speed manual transmissions (various manufacturers): Many 4-speed manual transmissions can be adapted, often requiring custom bell housings or adapters. Popular choices include those from Mopar (like the A833), Muncie, and BorgWarner T10. This option requires more mechanical skill to install.
* 5-speed manual transmissions (various manufacturers): Similar to 4-speeds, various 5-speeds from different manufacturers can be adapted; however, this is often a more complex and costly undertaking.
* Modern automatics (e.g., 4L60E, 48RE): These transmissions can be adapted, but this usually requires significant fabrication, custom parts, and expertise.
Factors to Consider:
* Intended use: Cruising, racing, towing, off-roading, etc., will heavily influence the best transmission choice. A high-performance application needs a transmission that can handle the increased torque and stress.
* Budget: The cost of the transmission itself, plus any required adapters, modifications, and installation labor, can vary significantly.
* Skill level: Manual transmissions, especially those requiring custom adaptation, demand a higher level of mechanical skill and expertise to install and maintain.
* Availability of parts: Some transmissions are more readily available with aftermarket support than others.
Before you buy: Always double-check the bellhousing bolt pattern and any other required adapter plates to ensure proper fitment with your specific 440 engine and vehicle. Using the wrong transmission can lead to significant issues and expense. It's often a good idea to consult with experienced mechanics or transmission specialists to ensure you choose the right transmission for your needs.
