RACING AND TOWING PERFORMANCE
OVERDRIVE ECONOMY
The Absolute Highest Horsepower Handling Overdrive you can buy!
Gear-Splitting Performance and Overdrive Economy.
For RV’s, Trucks, Muscle Cars, Hot Rods, and Racing.
The Finest Quality Auxiliary Transmissions.
The Ultimate in Horsepower Handling and Performance.
Even if you use forced induction (supercharging) on a 4L60 trans equipped vehicle it is hard to overcome the wide ratios. The vehicle cannot simply increase its vehicle speed 47% (the ratio split of the 1-2 shift) without pulling the motor rpm down a huge amount. Thus the more power you feed the 4L60 the more it converts to heat in its clutches and torque convertor. If you try to lock down the clutches without computerized torque management you break the transmission - there is just no way to work well with stock ratios that are equivalent to skipping a gear (going from 1st to 3rd - skipping 2nd in an M21 manual is only 41%).
The GEAR VENDORS will give you Gear-Splitting to fix those wide ratios with a gear between each of them for tremendous gains in performance. Because of these wide factory ratios there is no better example of the difference that can be made with adding a Gear Vendors. See Final Drive Ratios. Gains of over 50 horsepower and 70lb ft. of torque are easily achieved just by having the close ratios when you need them.
The GEAR VENDORS also gives you an important towing or performance overdrive gear that is between the tall factory overdrive ratio (4th) and Drive (3rd). This gear will give you 11% more torque multiplication and the right rpm when you want instead of the torque converter locking and unlocking repeatedly or lugging the engine. When towing, this gear will lower transmission temperatures by as much as 100 degrees when compared to factory overdrive. Cars and Trucks with 3.73 rear gears and higher (numerically) can also make use of double overdrive when not towing for 10-15% gains in MPG.
4L80E’s used in motorhomes and trucks have a .75 overdrive ratio very similar to GEAR VENDORS .78 but the factory unit tends to unlock and lock (hunt). The GEAR VENDORS will not hunt and will also reduce temperatures in the main transmission by as much as 100 degrees on warm days when towing. Consequently all our customers tow in the GV ratio and greatly extend the life of the trans.
Trucks running empty can make use of double overdrive for great economy and extended engine life. Motorhomes present too large a frontal area to
the oncoming wind to make double overdrive practical but because they are always loaded they greatly need the GearSplitting and alternative Overdrive features of the GEAR VENDORS.
GearSplitting is the feature that allows the UNDER/OVERDRIVE to shift between the gears. You will now have approximately ½ the drop of engine rpm from one gear to the next when you want power. This is why a GEAR VENDORS will give you more power than any underdrive or overdrive on the market (see Common Questions). By keeping torque multiplication higher and engine rpm narrower you increase engine performance by typically more than 40hp and 60lb ft. of torque without any modification to the engine (see Final Drive Ratio charts and Horsepower and Torque curves), (see also Common Questions on performance modifications).
This is why big trucks (Kenworths etc.) use gears (most 18 wheelers have 15 to 21 gears) instead of engine modifications. Because gearing gives them performance which actually improves the reliability of the engine. The heavier you are loaded the more you need a GEAR VENDORS.
If you already have engine modifications (chips, exhaust, fuel increases, etc.) the GEAR VENDORS will let you get the most from them through working in narrower rpm ranges when loaded and also by adding torque multiplication to make it easier on the engine and transmission so as not to damage them with your improvements.
I LOVE this addition to the transmission and the truck performs SO MUCH better everything the say on their site is true and honest HERE is a link to check out the parts direct from Gear Vendors ~ www.gearvendor...
just to note its not the trans that doing the clunk its the gear vendors there's no way of torque management or anything when it shifts so it has to shift like an th350 with a race shift kit for anyone that wants to know
Whoa!! That's a hell of a difference. I'm gonna look into this for my '75 Lincoln.
Its a pretty cool system!
I just picked up an 88 square body 3+3 dually with a 454. It has a 3 speed column shifter, I was gonna swap with a 4 speed floor auto. I got the truck with no info about it, and was working on her today and fired it up for the 1st time. There's tons of after market switches I was trying to figure out what they did, and discovered it has a Gear vendors. Just saved me tons! Glad I discovered your channel out of it. You seem alright...for a ford guy. 🤙
Learn something new everyday, Gear Vendors !! Thanks for sharing your knowledge and videos.
I've thought about getting a GV for my 85 C30 dually. With a 454, TH400 trans and 4.10 gears she'll really benefit from it.
I Kinda wish there was a 6 door Chevy Truck like that one from the mid90's
How does the overdrive work when you're doing full throttle pulls?
I've been looking for that info as well but too no avail
From what i have read and heard it wont split the gear until the final gear in the trans
The guys at gear vendors get their panties in a bind when you mention GV with a transmission that already has OD even though it's advertised to use double OD. California nuts...
I have been planning for years to install a gearvendor
You're gonna love it
Man I wanted this truck and you decided to keep it when it was in San Diego
Its for sale just had to pull a load to montana.... Its my womans daily driver now ;-)
*Cereal Marshmallows* It's awesome. Keep it up :p
I’d love to find an overdrive for my gmc 3/4 ton
Is the cucv for sale
Yes hopefully do a video soon ;-) Nathan 406 546 8748
I honestly wish it DIDN'T have the gear vendors. I mean it's nice and all for something that didn't already have OD but this thing turning 2200 RPM or w/e at 70 MPH is acceptable. I saw this truck on the site and got excited but I don't like that slamming into gear
Mines doesn't slam into gear! What fluid are you using?
Well....of you lived in California....this would be specifically for better fuel economy
Thx for posting
So like an 16 speed in an 18 wheeler?
no a 6 speed more modern like a 6l80e
Awesome video!
I have gear vedors in my 87 f350 dually crew and i cannot figure this thing out
Ever make any progress?
I just got a 88 f250 the other day, I'm lost aswell 😂
You running the GV behind a 4L60E!?
It's listed on GEAR VENDORS SITE for 4l60e.
It’s a 4l80 in that truck, being a 3/4 ton
How did the mpg improve?
It doesnt
nice system
Probably 4l80e in that truck.
That or a 4L60E. My money is on the 60.
4l80e.
That's an 88-98 body, the 3/4 and 1 ton stayed obs past 98, and they have 4l80e.
Nice Chevy truck man. Bummer the tranny/ torque converter is bad. To me, that sounds like the clutches in the torque converter are going bad. ( Not 💯 percent sure though. Love the headlight switch. Sure miss the old school. I hope things are going better for you than what they were man. Remember,do what makes you and your family happy. Life's just way too short. You're my friend man. And,I care about my friends. I don't have many good friends because most of them are sponges. (If you know what I mean). You my friend, aren't like that. I can tell your honest. And,in today's world, that Carry's weight man. But, whatever the scoop may be,I hope things are looking up for you. You have a good day man. And,talk to you later.👍✌️
This dude got so many trash cars… does one break and he just add it to the one day I’ll fix it pile.
