Buying Guide
Need more power and precision in your Chevy 383 or 400? Upgrading your transmission parts can transform performance and reliability.
- Compatibility: Match parts to your Chevy’s exact engine and transmission model. TH-400 pans fit GM systems, while pulley kits suit SBC engines (265-400). Double-check specs to avoid errors.

- Ease of Installation: Look for pre-installed drain plugs and bolt kits with flanged heads. These save time and ensure secure fits without extra tools.
