Upgrading your Chevy’s transmission during an LS swap can significantly enhance your vehicle’s performance and reliability. Whether you’re aiming for better torque, improved fuel efficiency, or increased durability, choosing the right transmission is crucial.
Understanding Your Options
There are several transmission options available when performing an LS swap. The most common choices include:

Preparing for the Swap
Before installing a new transmission, ensure your engine and chassis are compatible. You may need a custom transmission crossmember, driveshaft modifications, or adapter plates. Additionally, consider upgrading your clutch and flywheel if opting for a manual transmission.
Installation Tips
Follow these steps for a smoother upgrade:
- Drain and disconnect the old transmission carefully.
- Use a transmission jack to support the new unit during installation.
- Ensure proper alignment of the clutch, flywheel, and pressure plate if installing manual.
- Reconnect all linkages, wiring, and cooling lines securely.
- Test drive to check for proper shifting and operation.
Additional Upgrades
Consider upgrading your transmission cooler for better heat dissipation, especially if you plan to tow or drive aggressively. Upgrading the torque converter or installing a performance valve body can also improve transmission response.
