Installation of TCI 6X Six-speed transmission in project ?MaxStreet? Chevy II
 

If four forward gears is good, six must be better, right? That is what TCI is thinking, with the release of their 4L80E-based 6X six-speed automatic high performance transmission. For our powerTV Project MaxStreet Nova II, the 6X was right up our alley. We needed a transmission that can handle 850hp+ that will be produced from our Edelbrock/Musi 555 big block Chevy and F2 Procharger, while cruising at low RPMs on the highway as well.
