Rare OverDrive Unit found for the '37 School Bus

A friend of ours had this right down the street from us, and gave us a real good deal on it.. He bought it brand new in 1982, put it on his truck, drove it for about 40 miles, and sold the truck.. He took the overdrive unit out though before selling the truck, intending on using it in another truck later on, but never did.. We bought it from him still new in the box, with all the manuals and paper work..
It's a "Double Torque 2XT" , and was made by Power Torque Industries, Inc. Company, in Arlington, Texas..
It was made to bolt onto this SM465 G.M. four speed truck transmission that we are using..
We understand this company sold out to "Advanced Adaptors" and they continued building this same unit with very little changes.. They are now called the "Ranger Torque Splitter". .
They no longer have the Eaton electric solenoid though, as the earlier units did, and have gone to strickly manual shift.. Although we have the electric solenoid, we decided to manual shift ours also..
These units are basically like having an additional transmission, one in front of the other.. Instead of the standard 4 forward speed and reverse, we now have the option of having 8 forward speeds, and 2 speed reverse..
According to the manual, this unit is actually better than a standard 5 speed transmission in fuel economy.. You only get a 17 % increase in economy with the 5 speed, and a 33 % with this unit..
"A typical 4-speed driven at 55 MPH in 4th gear would have an engine RPM of 2450. That same transmission with the 2XT added, driven at 55 MPH in 8th gear would have an engine RPM of 1830, a drop of 33 % in engine RPM..
Another good thing about this unit, over the "Gear Vendors" overdrive unit, is that It is a better design being mounted on the engine, instead of the rear of the transmission, as it never sees the multiplied torque, like the Gear Vendors units, which see 6 to 7 times the torque.
We were glad to get this over drive unit, as with our 410 rear end gear ratio, it was going to be bad on gas.
