Matt Hartford takes you through building a Pro Stock transmission 

Matt, is calm, patient, and encouraging, a sign of a great teacher. I learned enough for a couple of days. All I can same is, make more videos.

Please note NHRA: Videos like this help promote the class. The more you know, the greater the interest. I have a suggestion. Have the cars back into the pits, so the fans can see the engine being worked on. Some of us like the mechanical part of the sport more than the actual race. Thanks for the video Total Seal team, and especially Mr. Hartford.

Matt you've got the patience of a saint , Go Joe .

Tons of respect to Matt Hartford. I have never seen a team take the time to put school in session, especially on the Liberty trans. I have one for the N/A 10.5 car, with Prusiensky Hemi power, I am building for the 2021 season. Was worried about getting in to the thing, but you have given me some insight and a starting point. Thank you. If the NHRA makes to Pomona, I will see you run there. Thank you again.

I love hearing what Matt said (inline w/ what Joe was talking about) and I'm paraphrasing a bit; "Everyday you can learn something from somebody, because everyone has some sort of knowledge that you don't have" that is something I have always lived by and share with people, super awesome to hear!! Mega respect to you guys.. super insightful... I just felt I needed to add that to the comments :)

Heck yeah a long video!!!! Thank you guys!!!!!! You guys definitely needed a good combination of 5 to 10 minute videos and 30+ minute videos! It always bummed me out when the videos were less than a minute, etc. GREAT video!!!

As a gear-head, these are the best vids on RU-vid. Thank you.

Great vid! I can't get enough of these technical hands on vids. Matt and Joe do a great job too.

Omg 26 years building race cars and owning repair shops, it's really cool to see some improvised tools and moves even in pro stock haha.

Your videos have made me a fan. Mission accomplished.

Matt is just a Super Guy!!! Combine that with Joe's enthusiasm... NHRA needs more of this! I am a long-time racer since the early 1960s. Been in Comp, off and on since the 80's. Matt has the heart of a teacher... patient, calm, understanding and a passion! And he is right here in our town... Phoenix, The Valley of Sun... and Matt really shines! And we are customers of Total Seal since forever! Great work Matt Hartford... and Joe!!! (Joe is from my home state of Florida)👍👍

This video is AWESOME!! :) Thank you so much, Matt and Joe! Automotive engineering is fascinating, yet much of it (especially in NHRA drag racing) can be a mystery. Thank you for the informative tech session - really enjoyed and learned a lot from it! Looking forward to watching more videos! :)

One of the best drag racing related videos I have ever seen, and it doesn't even have a car in it.

This was amazing! Think about this: A wheelie bar adjustment can affect an ET. A gear change can affect ET. A thousand little things can. I just saw the entire Pro Stock field at the 2024 Gatornationals was within 43 thousandths of a second.

Designed just like a twin counter shaft truck transmission. Good video guys!!!

Great video! Thoroughly enjoyed it. Thank you!

Ty for sharing this and why I'm a fan of Matt's.

What a Nice vídeo from nhra, thanks for the content, teatche and also A Jornalista...

Incredible. Thank you for this step-by-step tutorial. I’ve long been intimidated by transmissions but now they make sense. Matt is an exceptional teacher.

Great Video! And Congrats to Matt and the now "multi time" (2) NHRA Event winning Total Seal Pro Stocker Team on their Seattle Win!!! And stopping Greg Anderson on a WesternSwingSweep!! Ouch lol ... I predict many more wins in this teams future!
