The 450E is designed for testing automatic and power shift transmissions used in commercial applications built by most popular OEM transmission manufacturers. This quiet, compact machine has been progressively engineered to facilitate quick transmission coupling and alignment. The 450E will perform the diagnostic tests to evaluate performance and troubleshoot faults.


  • Ease of transmission connectivity. Splined input allows for quick positioning and takes the guesswork out of alignment
  • Driveshaft output connection eliminates the need for precise alignment and also eliminates vibration
  • Extremely quiet design aids in troubleshooting the transmission
  • Capable of applying measurable output load to the transmission to confirm integrity, monitor noise issues and simulate actual operational conditions
  • Dynamic Load Sensing (DLS) reduces input torque as needed to eliminate shift stacking
  • Indexing allows the transmission to be rotated/indexed for ease of access to the valve body
  • Can test in-line, remote and mid-ship transmissions as well as drop-box output configurations (maximum 14.9606 in (38 cm) vertical offset)
  • Integral oil flow measurement, cooling and filtration
  • Integral drain sump with pump and filter to reuse oil
  • Conveniently placed filters and ten taps for pressure monitoring
  • Transmissions with SAE #1 flange mount directly to the 450E. Adapter rings are available for other SAE sizes
  • Requires minimal floor space. Input power of 380-460 VAC 3 PH 50-60 Hz
  • Adapter kits available for all Allison transmissions as well as other major makes and models
  • Provides printed reports (customized with your company logo) of the test results including shift patterns
