Inside the Transmission of an NHRA Pro-Stock

I'm going to tank the car chief on Jonathan Gray's car I'm going to give you a quick rundown on the liberty five-speed that we run on a postcard your shifter you lift this lever up and it goes in the first year let's the clutch out when the tree comes down and he never uses the clutch again second gear third gear fourth gear fifth gear you're ready to pull the chutes same thing with the bottom half this transmission is upside down so we've got first gear right here second gear right there third gear right here fourth gear here nine fifth gear here and then everything is running together they can take about a quart and a half is all we run and the easiest way to change the system dumb pit in when the apart upside down we're putting the Valvoline in takes about a quart and a half is all it takes and then these transmissions we take them out in the car every single we run down the racetrack and the reason we do that is we try and we try and optimize our are run by changing first year second year third year whatever we need to change for track condition weather conditions and it's a last-minute call so we got to do a transmission teardown change the gear back together usually in about ten minutes if we can if we got that much time

10 minute transmission change and you thought a 6 sec pass was fast.

I know I don't need that, but I kind of need it.

It's been maybe 10 years since I've been to an NHRA event, but I remember the pro stock pits you could basically walk right up to the cars while they were working on them. It was crazy to see how fast everyone moves to disassemble these engines and transmissions before the next race.

That was cool as fuck

What are the major downsides of using this in a performance car on the road? Are they even legal?
