A transmission dynamometer measures the torque a transmission can handle without failing. Choosing the right one depends on the job and available space. It can detect leaks and faults, and heavy-duty versions are ideal for large trucks. Manual transmissions require specific testing procedures.
A transmission dynamometer, commonly called a transmission dynamometer, is a piece of automotive test equipment. The machine measures the torque that a newly rebuilt or new transmission can handle without fail. Selecting the best transmission dynamometer depends on what it is used for and the space available to maintain it. A transmission dynamometer is available in various levels of service. The heavier the job, the more torque and load it places on the transmission and the more space it typically takes up.
When using a transmission dynamometer, the load applied to the transmission is adjusted through a user interface, and the interface alerts the user to any faults that occur. The transmission dyno also applies hydraulic pressure to the transmission so it can be checked for leaks prior to installation. Detecting these leaks prior to installation can save time, energy, and money.
A heavy duty transmission dynamometer would be ideal in a shop that handles large truck transmissions. These versions can apply heavy loads to transmissions used in large trucks designed to carry heavy loads. This capability is a must, because failure of these transmissions can be costly; Transmissions are expensive to replace, and such failures would mean truck shipments are late.
A medium-duty transmission dyno is a great option for a shop that does work on large trucks and cars. This transmission dyno can handle the large transmission used in 1-ton trucks, as well as the smaller front-wheel drive transmissions used in passenger cars. They’re also ideal because their small size means the space for them can usually be found in a medium-sized store.
A light-duty transmission dynamometer is ideal for small to medium-sized transmission repair shops. These machines allow rapid testing of all light truck and passenger car transmissions prior to installation. This prevents vehicles from coming back and also saves the work of having to uninstall a transmission if there is a problem.
Another thing to look out for is manual transmissions. A manual transmission requires a slightly different testing procedure that some transmission dynamometers may not perform. Choosing the best transmission dyno means making sure it’s capable of testing what you need to test, including manual transmissions.
Without a transmission dynamometer, a transmission must be installed in the vehicle and tested. This is an unreliable way to dynamically test a transmission, and if a fault occurs, the transmission must be removed entirely. The transmission dynamometer eliminates that and allows the user to easily locate problem areas, because the entire transmission is visible while in operation.
