Buying Guide
Choosing the right 4L60E torque converter involves considering a few key factors. Stall speed is crucial; it’s the RPM at which the converter begins to transfer power efficiently. A higher stall speed is great for racing but can be less practical for daily driving. Also, consider your engine modifications. A stock engine won’t benefit as much from a high-stall converter as a modified one will. Finally, think about your budget. Torque converters range from budget-friendly to high-end custom units, so find one that fits your needs and your wallet.
Here are some tips to help you choose:
- Determine your stall speed needs: Match the stall speed to your engine’s power band and intended use (street, strip, or both).
- Consider your engine modifications: A modified engine can handle a higher stall speed converter better than a stock engine.
- Check the converter diameter and spline count: Ensure the converter is compatible with your transmission and flexplate.
- Read reviews and get recommendations: See what other users have to say about the converter’s performance and reliability.
- Set a budget: Torque converters range in price, so determine how much you’re willing to spend.
