2 Gearshifts | Twin stick shifting in my Grandpa’s old Mack 

What an absolutely beautiful truck Sam. Glad you and Matt are keeping these old beauties around for all of us to enjoy

I did some work for an old Japanese farmer who had an old Hayes with an 871 Detroit with a 5&4 setup, that man made that truck sing, never missed a shift and no grinding gears. It was a thing of beauty!

Beautiful demo of the Quadruplex. It really does paint the picture that this old iron has a personality and a mood.

In my opinion, this is one of the most beautiful trucks ever and I have full admiration for anyone who can shift gears cleanly

This sure brings back memories! I learned to drive on an old LF mack with three sticks. Five speed main, three speed aux and two speed rears. My uncle taught me over a period of three summers. He could split shift all three without using the clutch. His hands were like a blur. He could make that old Mack scream. No Jake. It had a big water tank that he could spray water on the brakes to keep them cool. They don't make truckers like him anymore, God rest his soul. Great video, thanks.

❤ THAT MAC! I’m sure you and Grampa made a lot of memories together. He’s right there in the passenger seat EVERYTIME she is in use! As for me I could watch you shift her all day, what a great video ,thanks SAM!

Truck is definitely be theft proof with a 2 stick shifter in today’s society, most people can’t even handle a 4 speed manual trans today. The ole Mack is a beauty for sure, thanks for the ride along sir, enjoyed it.❤

Thats just about the best theft deterrant I've ever seen. Sweet truck.

Finally someone who can explain shifting well. 👍

That's a really pretty old Mack. I'm so glad someone cared enough about it to preserve it.

Grampa is still sitting in that seat watching you drive his truck! Beautiful trucks!

You were fortunate to have him.

Lou and Erma were 2 of the nicest people I've ever known. They were a key part of Brownsville's success. So glad that you are carrying on the tradition!

My uncle had the same exact truck when I was a kid . I’m 72 now and I can still remember going along with him. Thought we were kings of the road.

I like the way you respect your heritage and the associated equipment- cheers

Beautiful truck .... amazing! And how you talk about your Grandpa .... is the nicest part. He still is with you as long as you have him in your heart. Awesome video ..... Thank you 😊

The LT's were one of the best looking trucks of the era and possibly the best looking Mack of all time.

Everything I see about you says you have a heart of gold. Your love for family, mates, equipment and also the way you relate to others. Your video editing has also come on in leaps and bounds; a lot easier to watch. Keep it up. May our Lord continue to bless you.

I love that truck. I met your grandfather several times but being 70 years old I don't remember his name. Keep it rolling.

Sam you grand father would be proud of the way you can drive and take care of his truck. Thats a beautiful truck . Thanks for taking us along.

Wow, I can relate to this video! While I didn't get any vehicles from my grandfather, I do have firearms, tool boxes, tools, and fishing gear from him. Every time I walk in my garage, I see his old long time tool cabinet and the new stainless one the family got him after he was no longer able to do much but he still had the desire. I use his win 94 lever action rifle to win the lever action silhouette matches at the club I belong to. I used to stop by his house after a match and show him whatever pins I won for that match. I still fish with the pole he taught me on back when I was in kindergarten. My dad is similar to my grandfather (mom's dad) and I am much like my dad's dad, who passed before I was born, and then my uncle (aunt's second husband) hired me as a teen to work on their house and with his painting and construction business, which just lead me further down the path of working with my hands. It is cool to see someone else who appreciates a similar background passed on by generations before!

She's a beaut, Clark. Love how excited you get driving grandpa's old truck. Really wish I had something and a memory like that I could've shared with my grandfather, but they both passed when I was so young. 😞

Beautiful job detailing the shifting and driving sir. Keep those traditions alive.

Thank you for this video. I drove two old Petes with two sticks. Both were water trucks built from old log trucks. Never had any instruction. Had no idea how to properly shift them. In fact, I got my Class A with no actual instruction. Single axle GMC 6500 5 and 2 speed and a transport trailer. Never really used my license but always kept it up just in case. 37 years. Last year, my doctors decided not to renew my physical. Major BUMMER.

WHAT A TRUCK! I really like the color too, sets off the chrome nicely. I really like the style of the older trucks.

Wow, your grandpas old Mack tractor is beautiful Sam! Love the paint scheme with tan interior and the British racing green exterior. Keep that bad boy in tip top shape and he will be with you smiling on every drive! By the way, she looks good pulling that dozer…

I came from a family of old school drivers, (I'm almost 70") and have heard so many stories of driving them old 2 sticks....always wanted to get my hands on one. I'm just an old driver livin a family tradition...but haven't driven one yet....Kudos to YOU Brother...(kinda jelly)

Can see the future where practically nobody will understand this., I love stick shifting best but don't even get the chance now. Twin Sticks are wild, thanks for the ride along.

Beautiful vehicle, I had run a 1961 B61 pulling an old Rogers lowboy back in 1969 and 1970. It was a retired Hess Oil tractor with over a million miles. Dual sticks were not easy!

Sam, your Grandpa sure did a very nice restoration, on that Mack. She sure is a Beaut! Love the twin stick stuff too. That twin cam, never missed a beat. You have a show stopper, and I’d you added Polished Aluminum wheels on the outside of the rears, it would just add to the appearance of the sweet Mack you have.😊

Gorgeous old girl! Really love those old trucks.

your grandpa would be so glad and proud of you for keeping his truck going. And it still looks brand new like it did the first day he drove it off the lot, so you're doing him proud, and he is sitting there with you like u mentioned.

Beautiful old Mack. a art to shift the gears on this old girl, but it still kicks butt pulling a load.

Well that totally screwed up my idea of how you shift a 5 & 4. lol Beautiful machine and well kept. Enjoyed seeing the old houses at about 8:20. My dream homes. Still more solid than today's offerings. Thanks for all this.

When I first started running cranes, 25 years ago, we had a few old cranes with "brownies". Except, in a crane, the cab is so small, the sticks are north and south, instead of side by side, like in a truck. Every once in a while, you'd get the rear stick (the main box) with your elbow and put it into neutral, while you were splitting with the front stick...and then you'd have them both in neutral. It was a nightmare to get through town with. Good times! And, it's kinda funny how times change. That Big Cam 400 Cummins was unbelievably powerful back in the day! We used to fight over the truck with the 400 in it. Now I don't think we own a truck with less than a 550hp engine in it, and they're just plain old trucks we use to haul boom.

Back in '68 & 69 i learned in R models and a B 61 how to shift duplexes....what an education for a kid!!

I couldn’t think of a cooler tractor…forest green old Mack with (my favorite) Big Cam 400 Cummins, and a 5+4 twin stick. Love it, love it, love it. Thanks for sharing suck an awesome truck

Sam, old is gold. I really love seeing that old Mack hitting the road. Thanks to you and your Grandpa...👍👍👍

I’m sure grandpa is proud of you driving that old truck

Sam it shows that you care about your grandpa and his memory. Good on you and your also keeping the old trucks alive they have such caricature the trucks I drive now are so generic you could be driving a Volvo or man or Scania or ford and you couldn't tell them apart. God bless you and Matt

The LT was one of the most beautiful Macks ever built. Grandpa did an unbelievable resto and update on it!. First vehicle Dad taught me to drive with was a long hood B with a triplex in an A & P parking lot on a Sunday afternoon many many years ago! Those old bulldogs where the best of the best. This old dog is in excellent hands! Goes to show “all good dogs go to heaven” . Thanks for the vid.

Sam your trucks are a beautiful example of an amazing age of trucking thank you Awsome video

God bless those men that had to deal with the 2 sticks! Hats off to your grandpa for teaching you!

I was hoping that Mack was still around! It was beautiful then, and beautiful now. Thanks for caring!

I learned on an autocar with a 5 and 4 behind a 350 bc cummins. Very few can drive old iron like that. Sweet ride, thanks for sharing with us.

Man, that is a great looking rig. Your grandpa did a dang jam up job restoring this piece of history. Thanks for the lesson on how to shift a twin stick. Will probably never drive one, but now I know how to 😂

I garantee Grandpa would be proud of you.

That is one sweet looking Puppy Dog and I have a soft spot in my heart for trucks with twin sticks mostly because I drove trucks with them when I first started driving

Nice old Mack! Looks like he done a great job!😊😊

Thank you for sharing your grandfathers Mac truck with us. I’m a third generation truck driver. I miss my grandpa and my father. Thank you for sharing man we love your channel and your content ❤❤❤❤❤

Absolutely immaculate.You must be very proud of yourself and that old girl .As l am sure your grand dad would be .l have never seen a quad box in operation before .Thankyou.

The L Model is beautiful and I was happy to see a modern day driver still double clutching. Your grandfather has to be proud of you.

Back in '79 I learned on a '65 Autocar with a 5 and 4. The truck I owned later had a Fuller 9 speed. Like your Mack it had a 22" steering wheel to go with the armstrong steering. Nice to see the trailer brake lever where I'm used to seeing/using it. Definitely a nice trip down memory lane -- thanks.

Your Grandpa was AWESOME!!

I absolutely love your grandfathers old Mack. Great job explaining the transmissions and showing how to shift the old girl. Driving those old trucks definitely separates the men from the boys. I really enjoyed the video thanks.

What a great tutorial on twin sticks I learned in a old Mack cabover in 1970. I miss my pops and grandpa 😢 thanks for sharing ❤

Sam you make some awesome content! Keep up the good work buddy! That Mack is beautiful and I’m sure your grandpa is proud of you

That is a gorgeous 1stack mack with the window in the back. Sounds awesome. Thanks for sharing that buddy.

You are a young man of character and integrity. The way you cherish the memory of grandpa vicariously through the lovely old Mack wow I am so impressed! You keep that tender heart and the warmth we feel from your channel you made an old lonely man feel like somebody must love me too somewhere. Keep up the good work you deserve much appreciation.

I’m not a truck enthusiast as such , more old British classic cars. Here in Northern Ireland we just don’t see trucks like this . This is simply one of the nicest , coolest vehicles I’ve ever seen. Clean lines , lovely colour , beautifully restored and most importantly, still being skilfully used ! Fantastic , I love it . 😎 Oh , and sound of that big Cummins 👌

For me, this video isn't about the twin sticks as it is that beautiful classic Mack.

Wow what an awesome job your grandfather did restoring that truck,it's beautiful and sounds so sweet,thanks for sharing Sam and stay safe.

I'm 68 yrs old and I drove a 63 Mack 10 wheeler dump truck with a cummins and quadruplex trans . One of the hardest 2 stick transmissions to master. Nice truck. Anyone would be proud have a beautiful classic like that.

Old American trucks are the best trucks. In looks and sound.

Great video Sam! Great truck! Motor sounds sweet! I miss your Grandfather too. He & Erma are/were a class act.

Very well done! No apologies necessary on grinding a little now and then, We don’t drive them every day and there is an art to it. Great point on timing stop lights. Headed into the first stop light at the Ballston Spa show I caught every gear going down to a red light without grinding and was quite proud of myself. The guy behind me talking on his phone and drinking a latte while trying to park under that big old Mack Differential was not at all happy for me. Great job and thanks for sharing!

Nice tribute to your grandfather. I'm sure he'd be glad to know the old truck still working hard.

That ol’ truck makes my heart go pitty-pat. Beautiful. As someone who has always appreciated the big tractors but never got to ride in one, thanks for taking me along for the ride and explaining the gears.

I miss talking with your grandfather about our buses we stayed in at the Brownsville show. He had the Mc5 MCI and we stayed in our 4104 GM. Very nice video Sam.

Beautiful truck, and it's great that it was your Grandpa's truck and what you learned to drive on.

What a truck she's a beauty I love big nose truck's there super cool, nice one Sam.

Grandpa's Mack is stunning, and I have never used that word to describe a vehicle. That Mack is truly an object d'art. You're not too bad throwin' those sticks but I'll bet Grandpa cringed a couple of times😉 Thanks for the trip.

Beautiful Truck, My first experience in a old Mack two stick was a B42 gas 6 cylinder , what an experience

Now that is truck driving. I had the pleasure to drive a 5+4 and a 10+4 in my career. Really liked them for the loads we pulled. Your Grandpa's truck is Beautiful. He did a Awesome job restoring it. Thank you Sam for sharing.

Thanks for this. Very entertanng. I imagine all that shifting keeps one very busy.

Man oh man, what a beautiful truck! And to have it be a connection with your grandfather is icing on top. I do remember driving one of those twin stick Macks in the 70's. Needless to say, I made a mess of it the first time out... And that yard with all that old iron. Would love a couple of hours there with my camera. Anyway, thanks so much for sharing this. John Vermont

Dude! That was totally awesome! I’ve never been in one of those trucks, and this is probably the closest I’ll ever get. I really, really appreciate this video. I think you did a great job on the shifts. Your grandfather would be proud!

Beautiful truck Sam. I remember my father talking about the old Mack two stick trucks. In Australia they called the secondary gearbox “Joey Boxes” because they were a baby gearbox attached to the mama gearbox :) I never got to drive one, sad to say. You take good care of that sweet rig!

Sam, way to show the younger generation what truck driving is all about. Twin Sticks are a lost art for the most part and its nice to see folks like you who are bringing these incredible machines to younger people. I for one drove modern trucks and fire engines. I miss the old B-model, L-Model, and CF-Model Macks. Love the rig you have. Sweet looking. Love the sound of the Cummins and Jake, but also love Detroits with Jakes. Grandpa is right there with you forever and is so very proud of you for taking care of his beautiful truck. Keep up the great work and hope to see more video's Driver!!

Man that truck is in great shape.

Thanks for sharing another great video 👍

4:33 I wonder if you notice the slots in the screws holding all the placards to the dash are all lined up horizontally and the crosshead screws holding the switches are also. Neat, and a sign of attention to detail. Beautiful truck!!

That Mack is a work of art on wheels. Glad to see it well kept and working well

That is an absolutely beautiful truck brother👍👍👍

excellent instructor

Boy - mastering those gears is a real art! Great video to watch - don't think we ever had the twin sticks here in the UK, but two speed back axles were quite common years ago.

What absolute beauty there. Manual transmissions are what makes a man a man. Those auto shifts are nice but anyone can be a steering wheel holder then

Sam that's a beautiful truck!!! Love the ol split windows!!

beautiful old mack

What a beauty!

Good job of gear swapping brother. That is one awesome looking Mac.

That is one beautiful representation of an oldie.. I just can't not love it. I started out a sales guy for 20 years, now I drive trucks and I absolutely love em..

Now that is REAL driving ... 😃 Thanks for showing how it is done! As far as I am concerned, I would have gladly watched the whole journey without any cuts - watching twin stick driving never gets old to me. And while you have explained the principal shift logic very well before starting, it was still somewhat difficult to figure out the reasons why you shifted at certain points (and why you did not shift at certain other points, although the engine sounded like a higher gear might make sense), because the viewer cannot 'read' the road ahead as the driver can (and has to). Also, it is somewhat difficult to judge the actual speed of the rig at any given time - I was quite astonished to hear that you were only going 20 mph at a certain point, it definitely looked faster than that to me.

Nice job Sam. That is a beautiful truck.

She’s gorgeous 👍🏻😊 Thanks for the ride. Ron

Enjoyed the video Sam. Your Grandfather did a great restoration on the 56 Mack. I believe you have the shifting down pat. Thanks for the video. You take care and God bless.

Nice old Dog.:)

Missing Grandpa too. 😢

I actually learned how to drive a stick shift trans on a Mack B-62 cement mixer. Never drove a manual trans, until my dad got me a job driving cement truck for the company he worked for. I had another driver show me how the two stick trans worked, then I took my turn and 15 minutes later I was loading up for my first haul. That was the most fun I ever had on a job.

Sam, The purpose of the "low low" in the compound box is so that when doing super heavy work and changing up gears on an uphill slope you can "grab" the next gear in the main box. eg if yo are in main 2nd and quad 4 and you want to change up then when you go to main 3 and quad 1 you actually have a lower gear ratio than when you started. This compensates for the ground speed that you lost when completing the shift. Once you are up a gear in the main you now have 3 more shifts in front of you with just the quad. I drove a lot of these with road trains in the seventies and eighties. I still revere the engineer who designed this amazing system
