        torque specs i am building my motor and trans up to handle to boost for a hellion twin turbo system . do you think this will help me spool up for a better launch at the line. thanks jesse

        • Definitely. I'm going this same route and have been doing a lot of research on the subject. A 3000 to 3500 stall with a turbo system is gonna be awesome!

        Will this work with 4R75W transmissions in 2004 GT's? I know this works with 4R70W trannys but does it work with 4R75W trannys?

        • The TCI Street Fighter 4R70W Lockup Torque Converter will only work with AODE/4R70W with a 10.625" bolt pattern only.

        • This would work perfectly with them! You will want to get a tune too.

            Improved 60' time!

            Great performance gain. Improved my 60' time by 4 tenths. Locks up good on the street. One pin was a little off at installation and had to be ground slightly at the shop. TCI could have had a little better quality control, but it hasn't been an issue. I would recommend this highly; between the convertor and 4.10 gears I took of almost a second in the 1/8th with drag radials!

            TCI torque converter

            Great product. Hard to say about the performance gains due to me installing a TCI streetfighter transmission also. Great improvement over stock by far.
