Why use the Schaffer Shifter?
Did you know that over half the transmission problems that come into your shop have nothing to do with the transmission?
The Schaffer® Shifter® electronic transmission tester is the professional's choice for distinguishing a transmission problem from a computer system failure.
In fact, more than half the vehicles that come into your shop with a shifting problem have absolutely nothing wrong with the transmission. In many cases, the problem is in the computer system that controls ignition and fuel system operation.
So how can you tell whether you're looking at a transmission problem or a computer system failure? The trick is to isolate the transmission from the computer system. If the transmission works when you control it manually, it's probably in good shape, and the problem is most likely in the computer system.
So why use the Schaffer Shifter? Because it’s the best transmission tester on the market today.
Years ago, if a transmission didn't shift, you knew right where to look for a problem: rebuild the transmission, and everything was back on track. But today's cars have changed. Computers control most of the major systems, including the automatic transmission. Therefore, it's entirely possible to have a transmission that won't shift, yet have nothing wrong with the transmission itself.
The Schaffer® Shifter® electronic transmission tester takes the place of the computer system to control transmission operation. So if the transmission operates properly from the Schaffer Shifter, you know the transmission is good and the problem is in the computer system.
On the other hand, if the transmission exhibits the same problems with the Schaffer Shifter as it did with the vehicle's computer system, you can be sure the transmission has an internal problem—it's that simple.
The Schaffer Shifter is specifically designed to provide reduced power levels to most solenoids. This enhances solenoid failures and makes damaged or defective solenoids easier to find.
The Schaffer Shifter is easy to use.
Disconnect the transmission connector from the vehicle harness, and plug it into the Schaffer Shifter harness adapter. Then go for a ride and use the easy-to-follow pictures in the instruction manual to operate your Schaffer Shifter and test transmission operation.
The Schaffer Shifter provides the transmission with the signals it needs to operate properly.
- To shift the transmission, turn the dial one click at a time.
- To apply the converter clutch, press the button.
- To check the pressure control solenoid, dial in the tester.
It's that fast and that easy!
