I think that Copeland is running an 8 speed Weisman tranny. They made it special for him.

Is that now vs. when the video was shot?
Here is my take after watching the video and probably not correct. The car obviously has tremendous HP. The video shows 1st, 2nd, 3rd and 4th gears. It looks like 1st through 3rd were basically useless. It would be interesting to know the transmission ratios and rearend ratios.
If the mph and tach data shown were correct here is what I saw.
1. The car was off the push vehicle about 5 sec. into the run and immediately experienced wheel spin with any throttle in 1st gear.
2. The 1-2 shift was at about 60 mph and rpm dropped to about 3300 after the 1-2 shift. Car was in 1st about 5 seconds before shift to 2nd. Second gear also seemed to experience severe wheel spin with any amount of throttle so the shift to 3rd was made about 7 seconds after getting into 3rd gear.
3. After the 2-3 shift rpm dropped to about 4000 with a car speed of about 110 mph. In third the same, wheel spin with any major throttle, so the car was shifted into 4th after about 8 seconds in third.
4. After the 3-4 shift the rpm dropped to a little under 4000 with the car running about 160.
5. The car then ran in 4th from 160 up to the top speed of 380 where the car was on the rev limiter. There wasn't much wheel spin in evidence while in 4th but no idea of the throttle position during this part of the run or the other gears. I'd guess they would also have a throttle position sensor and were data logging that.
If you have a lot of HP, like the car above, and the lower gears are very low you probably won't be spending much time in them. Their total time from the time the push vehicle started moving them until the shift into 4th at 160 was made was 25 seconds. I wonder if a higher 3rd along with a higher 4th would help the car. Maybe if they have a new transmission this has been addressed.
We found that with about 800+ HP with Hooley's car with the old engine we could never run WOT in 1st or 2nd and 1st was a high 1.93 with a 2.47 rear with about a 135 mph potential in 1st. Never got there also short shifted. We could run 3rd wide open and were in it for a long time before shifting into the overdrive 4th that was only 7% overdrive (.93)
One thing for sure is that their modified sports is one of the most impressive cars running right now
