Ive beating on my 1200hp plus transmission from PDD in my 2008 6.7 with s480/GT55 106 for almost a year now. I've been so happy with it that I decided to take advantage of this awesome sale so I had them build me a back up 48re rated for 1200hp plus. I daily drive my truck and when its time for a refresh I can have one ready to go.
Thank you Power Driven Diesel
