GM 3 Speed Automatic Truck/Motorhome

With the Gear Vendors dash switch in “auto” you will have overdrive just as if the vehicle came from the factory with our system. The dashswitch can either be mounted in our underdash bezel or the custom indash bezel like the Fleetwood Limiteds that came factory with our overdrive. This overdrive will shift on and off without your attention and can be used while towing up to combined weights of 30,000 lbs. An interactive floorswitch is positioned for the left foot (just like a headlight dimmer) to give manual control at any 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 up to 6 forward ratios (see final drive ratios). With approximately 1/2 the drop in engine rpm on each gear change and the ability to downshift at 1/2 gear 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 the horsepower and torque without modifications 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 OVERDRIVE you get this power because gears are multipliers of torque, plus the engine can be kept in a narrower (better performance) rpm range when power is needed. For this reason, if you do have performance modifications our overdrive 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 wear savings you get from slowing the engine down 22% so that the same rpms that currently take you only 500 miles will now take you 640 miles.

Most vehicles will experience mileage increase in the 20 percent 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 factory overdrive.

The gear vendors OVERDRIVE will do more for this vehicle then any Underdrive or Overdrive on the market. You will get all the features normally associated with an underdrive except a gear below first, plus all the economy of overdrive. Because Gear Vendors is the only product you can shift under throttle you will have far greater performance and economy. The Gear Vendors comes with the best money back guarantee . There is not room here to discuss every situation that arises where additional gears and torque multiplication help. Look at the final drive ratio and then call and get one, you will absolutely be glad you did.

At about $2200 dollars (depending on models) the Gear Vendors is not the cheapest way for you to get overdrive (a rebuilt wreaking yard 700r4 is probably cheaper) but the Gear Vendors is by far the best way. Horsepower handling is the first issue. Our overdrive will handle 1200+ horsepower reliably. This is why you have seen Gear Vendors in 8 second 1/4 mile cars in publications like Hot Rod and National Dragster. This is also why all GM Callaway Corvettes with automatics came with a TH400 and Gear Vendors instead or the 700r4 which is the base Corvette transmission. If you’re running more then 1200 horsepower (and we have customers that are) then talk to us as there are some hydraulic changes we do for vehicles up to 2000hp.

Horsepower aside, there are several other reasons you will prefer a Gear Vendors to any factory overdrive automatic. You will have a dashswitch that allows both manual 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 ). 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.

Another great feature of the Gear Vendors is that you will have a full 6 forward ratios when you switch to manual on the dashswitch. 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 gear 1/2 the time you are now so the car is not only faster but it also feels and sounds much faster.
