Testing and adjusting an Austin Healey A-type Overdrive.mov
Bench testing an A-type Overdrive for an Austin Healey 3000. Here you can
see how to check the pressure, how to set the operating vale, how to adjust
the solenoid and how to check the operation of the overdrive. Before
installing it in the car. All of these adjustments can also be performed
when the overdrive has been installed in the car.

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.

The MGB is a sports car launched by MG Cars in May 1962 to replace the MGA.
Introduced as a four-cylinder roadster, a coupé with 2+2 seating was added
in 1965. The six-cylinder MGC debuted in 1967; a later derivative fitted
with the Buick-based Rover V8 was made from 1973 to 1976.
MGB/MGC production continued until October 1980 variously by the British
Motor Corporation and its successors, British Motor Holdings and British
Leyland Motor Corporation.
