Us gear overdrive

With fuel costs high the overdrive can pay for itself in mileage and engine wear reductions. Gears are multipliers of torque and our Ratio Splitting capability allows you to shift to a gear with more mechanical advantage than the next stock gear in automatic transmissions and wide ratio manuals. And then shift to an overdrive final and reduce both rpm and torque to reduce the manufacture of HP when steady cruising to improve fuel mileage and decrease wear on the engine and engine driven accessories.

At the same time this ratio splitting makes less work for the main transmission in the vehicle to then advance to the next gear less ratio change and thus the main transmission itself becomes more reliable. This is a great benefit at the track or on the highway.

Only the import cars with manual transmissions had an overdrive gear. We have been reducing fuel emissions on the most powerful and fuel consuming gas and diesel vehicles for nearly 3 decades before Green House gas emissions became the buzzword they are today. With nearly 75, units in service we are reducing tons of emissions per day.

Whether you are driving a older non-computer controlled vehicle or a late model with all the latest emissions computers our electronics provide the interface to ensure maximum performance and correct rpm without lugging or overreving in the wrong gear. The OE factory programming remains intact and our processor just makes it aware of the actual ratio 1, of times per second.

In older vacuum or throttle linkage transmissions the stock governor on the output shaft instantly slows down the moment the overdrive shifts and so automatically moves the shift point in any overdrive gear up by the correct So both electronic and non-electronic automatic transmissions gain a group of features including a passing gear or climbing gear that is automatically available without driver intervention and is at the split between 2nd and 3rd where you really want it.

Electronic options also exist for racing and performance use such a paddle-shifters with our programming already installed by companies like MasterShift, and our AutoShift Sequencer that can work with stock and aftermarket shifters just like many of the race teams use.

These 2 terminals connect to the reversible 12v motor by means of a neat limiting switch. Ground is through the case and one terminal is 12v positive for high range and the other is 12v positive for low range. After last nights diagnosis session I'm not positive which is which, but I will figure that out later and post the info. I was unable to get any sign of life by hooking my jumper pack directly to the terminals, so the cover came off. I then bypassed the switch, same thing, nada.

So I pulled the motor. You can see it here as the thing on the upper right with the triangle-ish 3-bolt cover.

Slides right out after removing the limiting switch, just mind the wires so they don't get caught on the way out. This is just a picture of the other end, which bolts onto the transmission a TH in this case in place of the tailshaft housing.

In my case, all of the electrical connections were covered with a semi-hard black coating. I suspect this is a deposit from the gear oil that splash-lubricates the engagement mechanism? In any case, some time spent cleaning terminals with a bit of fine sandpaper and the motor roared to life.Due to shipper and supplier delays, your order may take longer to arrive. Display Options.

Most auxiliary transmissions are just dual ranges put them in low for towing, high for running empty but you still have the big gaps from one gear to the next that rob performance. You could actually go slower than you do now. Our overdrive is electronically superior.

Those older 3-speed automatics also adjust their shift points automatically because we slow down the governor on the trans whenever the overdrive is on.

For you this means the vehicle will not lug and will shift down to a passing gear that is really useful instead of just screaming the engine. In either vehicle you can put the electronics in auto and enjoy several features or flip a switch to manual and control everything about the gearing yourself. Take advantage of our 27 years of product development.

No matter how much enjoyment you derive from the improved performance of gear splitting on hills and overdrive when cruising, if your auxiliary transmission leaves you stranded in the middle of the highway, you'll wish you never made the purchase.

Guaranteed to 30, lbs. GCVW, the unit relies on a mechanical lockup roller clutch Sprague just like automatic transmissions do to handle the extreme torque peaks of initial take off and change of direction from reverse to drive.

It is a completely self contained system with its own integral pump and pressurized lubrication, features not found in any other auxiliary transmissions. Ask these questions of any other auxiliary transmission manufacturer:. Price is secondary, Reliability First. Power is certainly the No. There is no other auxiliary transmission available which can split gears as effectively.

In vehicles with automatic transmissions the unit is intended to shift at any throttle position including full throttle and delivers a crisp responsive shift. Shift it as much as you like. Vehicles with manual transmissions also benefit from the constant mesh planetary gear design as both in-shifts and out-shifts are as simple as depressing the vehicles clutch pedal and pushing a button.

No syncros to wear out, no grinding gears or mis-shifts possible. The systems sophisticated planetary design has very low friction which means not only will a Gear Vendors last longer, but it's quieter and has less power loss less than 1hp per hp than any other auxiliary transmission. All Gear Vendors overdrive offer a. Performance through proper gearing is the cornerstone of Gear Vendors overdrive.

There are many devices advertised as remedies for poor gas mileage.When it comes to acceleration performance, nothing sets you back in the seat better than low rearend gears. There is a price to pay for that stump-pulling experience, however: not so good fuel economy.

Of course, the introduction of the overdrive transmission has provided a compromise between both worlds. You can have a relatively stiff set of rear cogs, couple it with the low First gear of the tranny, and you get a decent amount of performance mixed with acceptable fuel mileage. Therefore, a need has risen for a simple overdrive that can provide you with the ability to run low rear gears and still take to the highway with that hp boulevard bruiser.

There are a couple of popular overdrives on the market, but besides being a few-thousand dollars prior to installationfew will take the abuse that the new V2OD from US Gear will. The biggest difference between the others and the V2OD is that the US Gear unit is a manual gearbox, not an automatic. Like a Muncie or Borg Warner four-speed the V2OD has a slider mechanism that engages a set of gears, not a set of clutches, drums, and wet plates.

OD On Performance

In short, it was designed with performance in mind, not towing capacity. Gear's new unit features an aluminum case that simply replaces the tailshaft and bolts to the back of the existing transmission. It's available in either a 20 or 30 percent reduction version, depending on what gear you currently have in your car.

The V2OD is a perfect addition to a street machine that is geared low for cruising Main Street and then blasting down the strip. With its 20 or 30 percent reduction, you can literally drive to the track without getting only 2 gallons to the mile. Recently, the gurus at US Gear approached us with the idea of putting one of their units in the ongoing Classical Resurrection '68 Camaro project. Along with the idea came the fact that it had never been done before.

With a resounding "yes" we agreed to the challenge and tackled the project to make the V2OD fit the tight confines of the First-Gen's tranny tunnel. If you haven't noticed, we tend to get excited about doing these types of "firsts.

With a few attempts at putting the unit in place, we quickly realized what needed to be done. This allowed us to orchestrate a chain of events to best complete this project. After a quick glance, we knew that clearance would be an issue.

We also needed to reroute the previously done exhaust system. Luckily enough, the Camaro doesn't have dual mufflers. It has a traverse-mounted, stock-style Flowmaster muffler. All we had to accomplish was to get the overdrive unit to physically fit in the tunnel, and the rest would be simple.

We also knew that the driveshaft that was in the car would have to be shortened a considerable amount--close to 13 inches as it turned out.

Fortunately, the solution for the driveshaft was literally right next door to the shop performing the installation. The final solution, or the best idea we could come up with to make the housing work, required applying a little heat to the tunnel's sheetmetal and using a small sledgehammer to increase the size of the tunnel. It may sound scary to some, but the amount of pounding required to make room for the V2OD was minimal and easily accomplished.

Once the room for it was created, the unit simply bolted in place. The linkage, which was redesigned, based on our experience, to be leveraged from under the unit rather than the side, is cable operated and easy to install.For over 55 years, US Gear has manufactured differential and transmission components in Chicago, Illinois.
