SWAP APPLICATIONS

The 8L90E is a popular swap transmission for:

🏁 **Classic Car LS/LT Swaps** – Modern 8-speed performance
🏁 **Hot Rods and Customs** – Smooth shifting, overdrive gears

🏁 **C7 Corvette Restoration** – Direct replacement for damaged units

**Required for Swaps:**
– Standalone transmission controller (for 8L90E)
– Custom driveshaft (unless using torque tube)
– eLSD controller (if using electronic diff)
