If you have this installed on a THM400, does the overdrive gear kick in automatically when you reach a certain rpm? By the same token, does it switch off automatically when you slow down and start in first gear again?
Good question. The unit can be manually shifted into OD or out of OD. If you leave the unit on "automatic" in other words in OD all the time time, what happens is it is shifted by the speed sensor. Below 45 MPH no OD. When you reach 45 MPH it will automatically shift into OD. Hope that was helpful. Good luck
With the gear vendors did it change the driveshaft angle alot as opposed to the original setup if I remember reading the gear vendors adds up to 12 inches to the transmission setup
Great video. I'm getting ready to install a GV unit in my Duster. Which video do you discuss the wiring up of the unit? You mentioned that you would cover it in an additional video. Thanks!
I have never seen anything like this ....i must live under a log Can this fit in most tunnels or do i have modify the tunnel Can they handle a lot of power say 700hp + Thats really cool for drag week
Well might put that one the wish list $6299.00 in Australia i can buy a lot of fuel for that price i dont drive my car enough to warrant one at that cost
@@troykane I would be concerned about this also, seems like a bit of weight for such a long skinny tail housing. With the gear vendors hanging off of it I would think there would be a lot of deflection and possibly crack the tail housing. Especially bottoming out on a rough road, which I know that car has no business on but it's a concern. An additional crossmember with a flexible mount just to support the weight but allow twist might be a good idea.
Not a hater but I did notice that you didn’t mention filling the overdrive with fluid just sayin no offense I have seen this be skipped and it was not good
@@troykane right now I’m just browsing. I’ve got a Hemi in my roadrunner and I’d like to be able to go back with a 4.10 DANA and still be able to highway drive it when I want.
@@southernoklahomamopars6726 the gear vendor provide a 20% decrease in RPM in OD. So at 70 MPH you are probably between 3000-3500 RPM now. So the Gearvender will drop that by 6-700 RPM.
Awesome video Troy. Loved to have seen how you setup the wiring inside, is there a switch for split shifting? What I’m talking about is do you have to cut the switch off and on each time you shift, if you follow what I’m trying to ask. Thanks for your videos 👍
There is a dimmer style switch on the floor to switch in and out of OD. The unit will shift by itself if you leave the swith on, so when you slow to a stop it drops out, when you re accelerate it shifts up. Sorry, I never made a wiring video. Thanks for the comment.
Easier with it out. You could install with the transmission in, but it's more accessible out of the car. Plus you can clean it, put a front seal in etc.
The gear vendor is around 2500. The advantage is you get to use the old school tried and true transmission original to the car. Plus you don't need a computer to control the transmission.
Listen .. this is an INTALLATION video .. why do you skip over every single section of the actual INSTALATIION ... FFS :( "OK, were going to install the (say any part) .. *pause video - return to action* OK THAT is all INSTALLED now! ... :( FFS
You lost me in the first minute. I don't care one bit about how many nuts and bolts were restored in your Charger. Quit bullshitting and get on with it.
What's your problem man? This man explained things really well IMO. Maybe you should try to learn something instead of being jealous about that damn nice looking car.

I love how you explain the process, great job
Thank you
Great Instructional Video.
Do like the wood on the ceiling ! I have a gear vender I bought it in 1990 but great video
Thank You!
Thanks for the video the long tail shaft is similar to the one for my c6
I'm going to install this weekend ☺️
Thanks for the comment. Good luck on the install.
Hey Troy! Great video I put a Gear Vendors in your old c-10 last summer. They're great units.
The truck must be awesome with with the overdrive.
If you have this installed on a THM400, does the overdrive gear kick in automatically when you reach a certain rpm? By the same token, does it switch off automatically when you slow down and start in first gear again?

Really enjoy your channel!
Thank You!
With the gear vendors did it change the driveshaft angle alot as opposed to the original setup if I remember reading the gear vendors adds up to 12 inches to the transmission setup
Good question. It did change the driveline angle. But, with the adjustable suspension I could change the pinion angle.
Hi Mr. Is there a version for Japanese cars and is there a part designed for front-wheel drive cars?
Not that I know of
Can you install this on a 904 without pulling the transmission? thanks
I believe you can. Call the folks at Gearvendor they will help you
can an overdrive be added to a commer autosleeper van with a sunbeam engine all original? Ya think?
how much of the driveshaft did you have to remove?
I do not recall. Generally 12-14 inches
Great video. I'm getting ready to install a GV unit in my Duster. Which video do you discuss the wiring up of the unit? You mentioned that you would cover it in an additional video. Thanks!
I lost the video. It got corrupted. But the wiring is pretty straight forward. Thanks for watching and commenting
Did u need to get a custom length driveshaft made? This product might be the solution im looking for with my c6 trans
Yes the driveshaft will have to be shortened.
Just subscribed! Looking for an overdrive transmission for our 70 challenger restomod. Thanks for sharing
Thanks for the sub! Good luck!
I have never seen anything like this ....i must live under a log

Thats really cool for drag week
They are Bullet proof.
@@troykane i just read the message under the video which answered my questions
Yes it will fit. I had to do some dimpling of the floor to really tuck it up in the tunnel.
@@troykane i have seen a few videos now
This is a really cool item
Well might put that one the wish list
$6299.00 in Australia i can buy a lot of fuel for that price i dont drive my car enough to warrant one at that cost
Do you need a crossmember for that thing?
no it's self supporting off the transmission
Seems like a lot of weight hanging on that adapter housing
Nope. It's not that heavy.
@@troykane I would be concerned about this also, seems like a bit of weight for such a long skinny tail housing.

@@stevenbelue5496 It's fine, they are proven to hold up to thousand of horsepower and hundred of 1/4 mile passes.
Good video! Bunch of haters in comments smh … it’s been a few years how you liking the gear vendors and how is it holding up so far ?
It's bullet proof. Works like clockwork. Thanks for the comment
Not a hater but I did notice that you didn’t mention filling the overdrive with fluid just sayin no offense I have seen this be skipped and it was not good
@@treyvader woops, Wait it needs oil?
What rear gear are you running? And if you’ve had the car on the road what RPM are you turning at 75-80 MPH?
I’m running 3:55 gears. I’m turning 1800 at 75 mph. This combo works great with the 383. Thanks for the comment. Good luck on your project. Troy

If you have a Ford AOD what would be the benefit of putting one behind a vehicle that already has OD? Would be even better wouldn't it??
I think it would depend on the rear axle ratio. Also the intended use of the vehicle.
Good job I think I learned something
Glad you enjoyed!
Nice video. Have you installed in the car?
yes. Works Great
I think you are good to go
Counting how many times you say Snap ring.
Snap Ring!
I just ordered mine for my 440 6pack challenger. Trans has to come out right? Can you install it assembled?
Easier with it out. You could install with the transmission in, but it's more accessible out of the car. Plus you can clean it, put a front seal in etc.
Need something on a install on a g4500 5 speed Ram, manual,
Sorry I've got nothing for you there.
How much was the add on vs changing to different transmission
The gear vendor is around 2500. The advantage is you get to use the old school tried and true transmission original to the car. Plus you don't need a computer to control the transmission.
Good video
Thanks
Through video great reference
Thanks
Work for Ford F-250 1967 4 speed manual??
Contact the folks at Gearvendors. They probably do have a kit.
Fuck yeah nice car
Well said
Did you have to shorten the driveshaft?
Yes absolutely. I do not recall exactly how though.
SO YOU WILL WIND UP WITH A "SHORTY" OF A DRIVE SHAFT.
Well, a shorter drive shaft
there is absolutely no need for such a long adapter like that one , make it the same length as a 4wd adapter and then bolt the overdrive in
Long tailshaft 727 torqueflite requires a long adapter. Unless you change the outputshaft. This set up is a direct conversion for this application.
@@troykane well that explains why owners of that transmission complained about cracked tail shaft housings, that tail shaft housing is stupid long
Listen .. this is an INTALLATION video .. why do you skip over every single section of the actual INSTALATIION ... FFS :(
"OK, were going to install the (say any part) .. *pause video - return to action* OK THAT is all INSTALLED now! ... :( FFS
Doing my best. I'm a one man show. I am learning the video editing and it's not that easy.
Oh my god, I tried to watch it further and you got back to the Charger again. Quit your bragging and stick to the topic. Waste of bandwidth and time.
Sorry you didn’t care for the video
the 66/67 chargers are ugly, the 68/69's are gorgeous !
Beauty is in the eye of the beholder.....
You lost me in the first minute. I don't care one bit about how many nuts and bolts were restored in your Charger. Quit bullshitting and get on with it.
Perhaps you could skip the parts you don't like.
What's your problem man? This man explained things really well IMO. Maybe you should try to learn something instead of being jealous about that damn nice looking car.
Always gotta be 1 in the bunch !!!
Great job Troy 👍
I like the video sir
