This trany has been in the car for 5 years now and driven on the street a fare amount, it maybe has 50 passes on it. I shift @ 7500 rpm and the sec gear pro shift gears just can not take it it just grinds, third gear is super pro ( face plated ) but I have just stuck to what I no works, nothing worse than grinding gears at the track. I get very little test and tune time at the track I just don't like waisting passes, this year I got in 9 passes total. My clutch from Advanced clutches was not working write after examining it I found that one of the levers are shorter than the other two, I have sent it back for repairs. the car cam out soft and slipped in 3,4th gear. here is one vid of my first pass on an 1/8 mile at an air port with this 416 eng and clutch.
