I did, lasted 73 miles the first time, about 2000 2nd, found out the TPS was bad and not building pressure, by that time I was afraid of it so went manual after 6500 miles, transmission pressure gauge should be included. I should clarify that the eng was 635 HP and 665 Torque then, at the upper limit of the trans capability.
I figured that would have short lived lol. I was on the list 4-ever for the 855 I just can't wait anymore. I don't care to cut my tunnel up and the T-56 Magnum is a great Trannsmission and I also went with the close ratio.
