I haven't personally used FTI converters for a 4L80E, but based on reviews and discussions in the automotive community, FTI generally has a good reputation for performance and reliability. Many users have found them to be competitive with higher-priced brands like Circle D while offering cost savings. If your current Circle D converter isn't performing as expected and you're looking for a more suitable replacement without the hassle of shipping back for modifications, FTI could be a viable option. It's always a good idea to research specific user experiences and possibly reach out to FTI directly for any technical questions or concerns before making a decision.
