Gear Vendors's Complete Kits Ensure a Smooth Installation for You
Gear Vendors overdrive Kits are Complete with Adapters Our Gear Vendorss overdrives are supplies with specific adaptation kits for each model of transmission model, the kits are completed. By supplying specific extension housings to each model/brand transfer case Gear VendorsS is able to have a better product with increased engineering benefit to the final installation. Fact is, when you are in 4X4 there is very little desire to use GearSplitting and overdrive unless you are racing (and we do make the in-between kit for that purpose), it's 2wd where the benefits of overdrive and additional gears are most needed, see YOUTUBE video for more information. All our kits bolt directly to the rear of the transmission, you can automaticly control the unit or we suggest you flip switch when leaving city limits sign and turn it off when you get to next city limit sign. No additional crossmembers are required and you retain the factory ground clearance instead of moving the transfer case rearward which puts it at or nearer the middle of the wheelbase where ground clearance is most critical. You get all the benefits of the GearSplitting performance and overdrive economy (see your appropriate transmission under GM/Dodge/Ford 2wd) and the best auxiliary transmission you can buy.

With the Gear Vendors dash switch in “auto” you will have automatic overdrive just like the vehicle came with a factory system. The dash switch can either be mounted in our under dash bezel or the custom in dash bezel like the Fleetwood Limited's that came factory with the Gear Vendors. The Gear Vendors will shift in and off without attention of the driver and can be used while towing up to combined weight of 30,000 lbs. An interactive floor switch is positioned for the left foot (just like a headlight dimmer) to give automatic control at any given moment so that you can turn the overdrive on/off for performance and gear splitting. Performance while accelerating or climbing grades is greatly improved by the availability of 6 forward ratios (see final drive ratios page 12). With approximately 1/2 the drop in engine rpm on each gear change and the ability to downshift at 1/2 the intervals (much sooner than with the stock only transmission) performance gains of over 40+ horsepower and 60lb ft. of torque are typically minimum.
Most importantly you are getting this horsepower and torque without modification in any way to the engine. Any other way of increasing power (chips, induction, exhaust, fuel) all put stress’s beyond the original equipment. With the Gear Vendors UNDER/OVERDRIVE you get this power because gears are multipliers of torque, plus the engine can be kept in a narrower (better performing) rpm range when power is needed. For this reason, if you do have performance modifications the Gear Vendors also helps them work to their maximum potential. Not only do you get performance without engine modification, but the overdrive will pay for itself in fuel mileage alone. Add to this the savings in wear you get from slowing the engine down 22% so that the same rpm's that currently take you only 500 miles will now take you 640 miles.
Most vehicles will experience mileage increase in the 20percent region if driven at the same top speeds as they are without the Gear Vendors.Increased mileage and reduced engine wear is why all vehicles today come with factoryoverdrive
The Gear Vendors UNDER/OVERDRIVE will do more for this vehiclethen any Underdrive or Overdrive on the market. You will get all the features normallyassociated with an underdrive except a gear below first, plus all the economy ofoverdrive. Because our overdrive is the only product you can shift under throttleyou will have far greater performance and economy. This overdrive comes with thebest money back guarantee (see warranty for details). There is not room here to discussevery situation that arises where additional gears and torque multiplication helpyour vehicle perform. Look at the final drive ratio page and then call and get one,you will wonder how y0u ever got along without it.
Dodge 3 Speed Automatic PerformanceCar/Street Rod
At about 2200 dollars (depending on models) the Gear Vendors is not the cheapest way for you to get overdrive (a rebuilt wreaking yard 518/618 is probably cheaper) but our overdrive is by far the best way. Horsepower handling is the first issue. A Gear Vendors will handle 1200+ horsepower reliably. This is why you have seen our overdrive in 8 second 1/4 mile cars in publications like Hot Rod and National Dragster. If you’re running more then 1200 horsepower (and we have customers that are) then talk to us at the factory as there are some hydraulic changes we do for vehicles up to 2000hp. Click image to enlarge.
Horsepower aside, there are several other reasons you will prefer a Gear Vendors to any factory overdrive automatic. You will have a dash switch that allows both automatic ad automatic operation. With the switch in “auto” the vehicle will act just like it came from the factory with overdrive. The overdrive will kick in at 47 mph or whatever the EPROM is set for in our electronics and turn back off at slower speeds without attention of the driver. The ratio is .78 to 1 (see the final drive ratio charts on page 7). This equates to 28% faster vehicle speed at the same rpm. Or, take your existing rear gear multiplied by .78 (i.e. 4.10 X.78=3.20). In this example a vehicle with a 4.10 behaves just like it had 3.20s when the overdrive is engaged. This is just the right amount of overdrive as any taller would require a lock up converter or create excessive converter slippage. With the .78 to 1 ratio you’re good with any torque converter you chose for high performance street/strip use.
Another great feature of the Gear Vendors is that you will have a full 6 forward ratios when you switch to automatic on the dash switch Pull into low, accelerate, then hit our button (on the shifter or the floor), a green light appears indicating overdrive and your in first over which is right between 1st and 2nd . Then shift to 2nd and turn us off. Then rev back up and hit the button for 2nd-over. Then 3rd and 3rd-over. See more information on Gear Splitting in the Drag Racing section. The performance and sound of the motor is tremendous as it goes through 6 full throttle close ratio shifts. You are in each gar 1/2 the time you are now so the car is not only faster but it also feels and sounds much faster.

Dodge/Dodge Ram Final Drive Ratios
Find you transmission and rear gear multipliers above.The Final Drive Ratio shows you how many times the engine turns for one completeturn of tires. This Final Drive number is also your torque multiplier when in thatgear. Gear Vendors reputation for being to best is because of its sophisticated planetaryconstruction. This means Gear Vendors is the only auxiliary intended as a gear splitterbehind automatics and the nicest to work behind both automatics and automatics. Youare able to shift half gears that keep the engine in the power. Any auxiliary thatrequires you to let off of the accelerator or is not intended to shift frequentlyis not going to give you this performance.
