This video deserves more views. People have no understanding of how cool this really is because people mostly drive automatics. They are scared of manual transmissions. Lol
Thanks man. It’s a fun truck to drive.
I'm 60 and still shifting gears.. cool 😎 never looses to lazy.
Had 5 speed pick ups for 22 years. Miss those trucks. Silly twist knob on the dash of new trucks lacks manliness
Nowadays a standard transmission is called an anti theft device 😂
Wow! The cool factor just went up another 10 points on this truck. I wasn't aware of the mix/match on the drive train using GM and Ford components plus the over drive gear splitter.And a Cummins/Dodge engine. A trifecta of automotive companies. This truck is off the charts cool and built the way one should be and the main computer controller is sitting behind the steering wheel. Kudos again on the truck build. Not your average diesel swap.
Wow thank you! I did my best to make it into something simple, useful and tough. So far I love it!
Thanks for this video I just bought a 94 Cummins with an nv4500 with a gear vendors and I had no idea how to operate it so the shot of you in the truck splitting it helped
Great! Let me know if you have other questions or want to see something else.
This truck is a thousand times better then any new crew cab diesel.
Thank you!
Really nice build and I can tell you love it...thanks for building this and sharing it with us...
I just love the old trucks there just nice and simple to work on.
Finally! Someone uploaded a video of a manual transmission Cummins with a gear vendors. Thanks! Also, couldn't help but notice the ole rubber band around the push/pull switch to stop that rattle lol.
I gotta give it to you man! I’ve seen a lot of 5.9 swaps and yours is hands down one of the coolest I’ve seen!!! Very, very awesome man!! I’d like to see you really roll some coal and legit smash on those back country roads!! I wanna hear that 5.9 roar!
Thanks! I’ll try to take some more videos soon. Thanks for watching
Super clean interior! Beautiful truck bro!
I really want one in my zf6 7.3 powerstroke. Your video pretty much has me convinced
That is badass! I'm picking up a 1gen with a gear vendors set up on it. I can't wait to drive it!
Man you’re gonna have a lot of people (me included) trying to do this. That thing is a dream machine man, hell of a build!
Thank you! It’s been a fun project
Just found this again. I’m finally at the point where I’ve got my truck out in Virginia with me (93 dodge d350 12v getrag360) I’m looking forward to having the lower rpm’s at cruising speed when I finally tear into it
But does it roll coal? It’s not really cool unless it rolls coal.
Sounds sooooo good Seth!!! Great job!
Thanks man!
Hey dad great video thank you for sharing have a good day
I love this! Your truck sounds great!!
Thank you.
Awesome all around 🙌🏻🙌🏻
I am speechless. Bill Nye of the car world
I got 2 of these gear venders overdrives. 1 in my 94 150 4.9l zf5 and one in my 1997 f350 zf5. They are amazing for when you are climbing a long steep mountain and need a gear between let's say 3rd and 4th because 4th is a bit high but 3rd is to low. Love it. It's basically a super 10 speed transmission.
Yes, they are really handy! I love mine. Gear splits and the lovely double overdrive
Can you split 2nd or is the driveshaft speed still not high enough?
Nice set up. I'd like to build one like this someday
I've been toying with the idea of putting one of those under/over boxes in my truck for years. That 3rd to 4th shift in the NV4500 is just such a huge gap. It's definitely always felt as if you could easily squeeze a whole nother gear in between lol. Even 4-5 has quite a gap. Would be really nice to split those gears when driving the steep mountain grades on my commute home!
Gotta find a 12v with a nv5600
I have a GearVendor.
It works great with the NV4500.
And that's why I sold my 1993.
It sucks towing compared to my 2006 Dodge 24v with a G56...
But that p-pump 12v does sound nice!!!
Great exercise for the mind legs and arms. It’s all I need to replace the gym.
Hermoso, gracias por el video 👍🏽
Love that you can get those but I'd only ever want and special built 10 speed manual with 2 or 3 over drives. For my dream second gen 4x4 truck. I love to use Eaton Fuller for rt or rto transmissions but I don't want to cut out my hump in the floor to make it bigger
Very cool truck sir
this is amazing , wayy better than brodozer builds
Wow thank you!
If you're not careful, someone is going to offer you a large amount of money for this truck. You'll accept the offer (if you're not careful) and always regret it. Awesome job on this build, awesome!!!!!
Thanks for the video.
Absolutely! Thank you for watching it!
What a great truck!! I'm jealous! Makes me miss my old 92 Dodge with the 12valve cummins. I am thinking about adding this gear vendors over drive to my 6 speed manual 2005 ram 3500. I am struggling up the back country hills towing my 12k pound 5th wheel. 5th gear is too short and 6th is too long. 5th with the gear vendor over drive might be perfect.
Send it my boy, gear splitting is addicting and that double overdrive really helps on the highway when cruising
Nice video, ❤️❤️❤️❤️💯
Thanks for this video, it answered several of my questions regarding the Gear Vendors Overdrive. How much better is your fuel mileage?
perfection
Nice truck! I have an 88 V30 Western Hauler Chevy that I'm in the process of cummins swapping. I'm using a 12v ppump with an eaton fuller 6 speed out of a 95 f600. Going to use an np271 tcase probably. Thanks for the motivation!
You’re welcome! Thanks for watching. Your project sounds awesome!
Awesome.
thats everything I would want in a truck, bet that gear splitter is nice for towing
Sure is!
Love it
Thank you Ed!
Clean
Thanks!
Just like an old Jeep!
It's a Big truck.....powerful.....i don't know so much about Cars or trucks but congratulations to You because a Big work fix this machine.....
By the way i have the same camera equipment jajajaja
Thank JM! It was a lot of work but totally worth it! Thanks for watching and commenting!
@@redeyecafegarage7484 you sure that's not a NV 4500 5speed ?
@@bustersmith5569 all the truck specs are in the description. Yes, the main transmission is an nv4500 but it has an auxiliary transmission giving it 10 possible gear options.
@@redeyecafegarage7484 that's why I asked.. it said NV 3500 which is a very lightweight trans for a 3500.. TY... very nice truck for sure... You did a great job with it.. wish it would have came from the factory just like that 👍
@@bustersmith5569 thanks. Just a typo! I don’t think there’s adapter for a Cummins nv3500 haha! That would end badly. 😆 💥
😍 Very cool truck, and exceptionally clean! Did you use the off-road design 4wd conversion by chance, or was it a diy fabrication? It was pretty cool that the high pinion 60 aligned well with the GM frame rails! I may be mistaken, but the driver’s side spring perch is cast into the diff housing, isn’t it? You were able to use the stock Ford knuckles, and use the GM’s 2WD steering box and pitman arm?
I used all original gm brackets and parts from a factory 4-wheel drive frame. The axle I used is a hight pinion Dana 60 from a 79 f350. It’s a direct bolt in. They are one of the best 60’s ever made but are getting expensive and hard to find. I used all factory gm 4x4 steering parts.
@@redeyecafegarage7484
After asking about the truck, I found your videos and binge watched way past my bedtime. 😂
Man that’s incredible what you achieved in a home garage, and you have a lot of talent.
Detroit never built EXACTLY the vehicle we want, so it’s up to us to build what they should have!
Thank you! Anyone can do this stuff… it just takes a little time and a lotta CZcams 😆
Im thinking about the GV for my 2012 ram. I don't pull super heavy loads but i pull long haul and i'm worried about heat build up. I don't doubt the GV will handle the power just concerned about the heat????
Have you thought about putting a high idle adjustment knob in?
Do you have a video showing the gear vendors installation? I looked but didn't see any. I have a 96 Ram 3500 with the 5 speed manual that I've restored to tow a travel trailer and I am thinking about adding the gear vendors OD. Also, what kind of maintenance does the gear vendors unit require?
I didn’t make a video on the install. It’s super easy though. Just a few bolts. The wiring and getting the driveshaft shortened is the most involved.
Kinda makes me wanna do this to a Powerstroke 6.4L and a ZF6.
That would be a great swap! Fords make good trucks…..they just need a Cummins to be a great truck!
That’s a sweet setup. Did you need any brackets to mount that gear vendor?
Thank you! No brackets needed it simply replaces the tail housing of the transfer case. I show it in the end of this video.
Wow this is got me jaw dropped great truck, now I want one for my nv5600. Is secound gear to slow to split?
I would say around 30mph is where you have enough pressure to engage the od.
I wish I could split gears with my NV4500. I swear I could get 25+mpg with my 12 valve.
Hola modificaste el diferencial o que relación tiene el diferencial
Seems like the gear vendor unit is way more advantageous on the manual transmission
Yeah it’s handy. You can do the same thing with an auto too. You can manually split or setup the shaft box to do the same thing. They’re really cool!
Thats super cool out of curiosity. What mpgs did u get with this setup
Thanks. I average 20mpg
Does this lower final drive ratio, or just provide gap-filler gears between 3rd 4th and 5th?
It does both. It can split and also give you a double overdrive.
Great job on videos, How does Gear Vendors hold up to cummings torque?
It’s been handling it since 1996
I just purchased a truck with this setup, so can I just flip the switch and it'll work once I get to a certain speed or do you have to wait till you are in third. I have a sm465 3 speed with granny low. At what point can you split gears between 1st 2nd and 3rd or just 2nd and 3rd.
If the computer is hooked up there’s a speed sensor that needs to see at least 35mph before it will engage. The hydraulic pump is driven off the driveshaft speed so you don’t want to try to shift below 35mph. If you override that and try to shift going slow it will slip.
Did you have problems with driveshaft balance/alignment, who did the drive shaft mod?
Nope, the drive shaft was shortened and balanced by a professional driveshaft shop. It runs great at any speed.
Is that push/pull switch on your shifter what came with the gear vendor O/D or was that an aftermarket switch?
I’m not really sure. It came in my engine donor truck.
I agree with js6729, that push/pull switch is cool. Can you maybe take acouple of up close pictures of it so maybe I could locate one.
esto es mas que exelente, que marca y modelo es el divisor de sobre marcha?
Gear vendors
I’d love to buy this from you
Question cuz I am now the owner of a 88 chevy crew cab 3500 4x4 as well with a cummins but has TH400 and gear vendors. How do you like the nv4500. I been thinking a g56 possibly
I’m a fan of manual transmissions so I like the 4500 but the th400 is a great transmission too. Especially with the GV. I’m don’t get that excited about 6speeds. They’re big and just means you’ll be shifting more. Imo. But the g56 is a really good transmission it’s just not my cup of tea.
@@redeyecafegarage7484so update because I came to watch this again. Ended up buying a g56 last week for $1000. Got trans adapter I needed and will be installing soon and keeping my gear vendors also. Will result in a double OD ratio of .63:1 allowing me to keep the 4.10 in the axles for towing capacity
Is that a split axle? Or an overdrive? Is there a split trans? What is the build??
Auxiliary overdrive/splitter
what is your rpm at 70 mph in top gear and overdrive engaged? what is your mpg on the highway?
Rpm in double overdrive at 70mph is 1700. 19mpg town... 24 highway
@@redeyecafegarage7484 that's a perfect rpm for that engine and speed. Are you geared 4.10 or 3.73?
Yeah it is happy cruising at that speed. I’m running 4:10’s
Not gonna lie I have a gear vendors in my shopping cart rn 😂 Any advice or is this a only live once situation 😂
I love mine but it all depends on what you’re looking to do with your rig.
Now add in a hi low rear end
I would need a co driver for extra hands! 😆
Gear Vendors themselves told me I can't use it with an exhaust brake, so I ended up selling mine.
There was another option for a similar unit,which is a gear drive set up made by US Gear.
That's not true. I have been using mine for about 13 years on my 1990 D250 with a Cummins and a Getrag 360 and exhaust brake, and it works beautiful. The reason they say don't use them with exhaust brakes is due to some people not having common sense to not splitting gears while going down grade or slowing down. I kick GV off and drop a gear or two down grades and use exhaust brake with no issues. About 245k miles doing that with no issues, I love my gear vendor and exhaust brake.
I do tow heavy, I run between 10k-21k depending on trailer I'm using. I tow cars smaller backhoes and sometimes forklifts.
That weight is truck, trailer and load on trailer so it's gross weight.
@@cppower14 man this is great news. I have wanted to get a gear vendor for so long but I was too worried they would not hold up long enough to make it a worthwhile upgrade cost. I'm so excited. Was it difficult to install? I have a nv4500 2000 24v and a 1997 nv4500 12v with 4.10
Driveshaft work is the hardest part of it all. If you purchase a vendor for you application it's almost a direct bolt in. Mine is a 2 wheel drive and it was stupid simple
How difficult was it to do the 5.9 swap?
Not bad at all. Some of the videos before this show the process.
I’m thinking about doing this to my TBI 350 sbc. My question is was this a pain to install?
4 bolts, wiring and shorten the rear driveshaft
@@redeyecafegarage7484 what about the fly wheel clutch assembly etc etc? You wouldn’t happen to know if someone sells a conversion kit would you?
@@redeyecafegarage7484 I’ve got a great question what shifter did you use or should I use? I’m keeping my center console so that means I’ll have to get a long shaft and I’ll have to manipulate it by cutting and welding and heating up and bending. I’m looking but they all are expensive and I don’t want to pay 2-300$ when it’s going to jacked up to fit me.
That's cruising.
Seth, do you have a video of installing the gear vendors overdrive?
Not specifically. It’s pretty self explanatory. 5 bolts and 2 wires. You do have to shorten your rear driveshaft thought.
@@redeyecafegarage7484 ok, thanks Seth!
Mind going in more depth on how you did this? I’m gonna do that as soon as I have everything
How I did what?
@@redeyecafegarage7484like the whole drivetrain like engine, tranny, t case and OD
What's with the clutch it's necessary I've seen ram's but not a chevy
I’m done answering clutch questions. Haha.. drive your truck however you like!
when you have to push in the clutch every time you hit the switch
You don’t have to clutch to shift the overdrive but in some situations it’s smoother and easier on the drivetrain.
They were fixing to get them a camera, don't sugar coat it.
What are your rpms in straight vs split 5th gear at 70mph?
Direct is 2200 overdrive is 1750
That's 8 speeds.
Not being able to use it until high into 3rd is why I never got one.
I pretty much only use it to fill the gap between 3rd and 4th and as a final overdrive. I don’t tow heavy enough to need to split the lower gears.
@@redeyecafegarage7484 From what I learned researching gear vendors, there is not enough pressure built up at the lower gears to use it before 3rd.
So 10 speed would be impossible, this is why I never got one.
My experience with the Gear Vendor is it wouldn't shift into over in second consistently, and it didn't hold up to pulling a trailer.
They require minimum of 35mph driveshaft speed to shift properly. Mine has been pulling trailers since 1996. Everyone makes fun of me for using the clutch to shift mine 😆 😆 jokes on them. If you use it correctly they last. You cannot lug them, you cannon engine brake with them and always use the clutch. Then they will last.
What is your tire size and axle gear ratio?
32” 4:10
My friend how much cost the gear vendor ???
Around $3500
What state are you in ??
Pennsylvania
What was your mileage on a trip with this
20mpg empty.
Ok. It’s an overdrive right?
Gear vendors.
Drive it like thirteen...
It's really too bad that 2nd can't be split, the 2-3 shift is an even a bigger jump than the 3-4 shift.
I don’t tow heavy enough to feel the need for a 2-3 shift. The 4:10’s help with that.
What could you possibly tow with a pickup, where 2nd would need split lol…it’s a pickup truck for crying out loud put 4:10s in it and keep it moving Jimmy 😂
I’d like to know how well that holds up under will say somewhat abusive conditions I hear that that gear vendors doesn’t hold up real good under is the abuse from a diesel engine then again I heard other people say it does I’m not making a comment either way I’m just saying what I’ve heard anyways this is six and a row Jim from Kennerdell Pennsylvania I have a 91.5 dodge too so anyways your truck sounds pretty darn good and I Magine that gear vendors will do OK they go well with the against big block Chevy’s in drag racing so anyway I don’t know
This one has been in service behind a 12 valve since June of 1996. Most of the people with negative reviews are idiots that drive like horny 17 year olds. Haha! Use your brain and you’ll be fine. 😆
It’s gotta be 4wd
SHOW THE RPMS AND SPEDOMETER
I have videos like that on here somewhere.
Little millennial and Gen z kids are good at Playstation but I'm sure you can leave the truck unlocked-
No worries with this anti-theft device
My mother in law has a 2005 dodge with a Cummins but she floats all the gears.
