When it comes to testing and evaluating the performance of a transmission, there are a few key factors to consider. In this operational test of the GearAR Performance transmission with the invoice number 8334 4 l60e level four, we will take a closer look at the various components and gauges that play a crucial role in determining the overall efficiency and functionality of the transmission.

Mainline Pressure and Cooler Pressure Gauges:

One of the first things to pay attention to in the operational test is the mainline pressure gauge on the top left of the gauge panel. This gauge provides valuable information on the pressure of the transmission fluid in the mainline, which is essential for ensuring smooth and consistent performance. Additionally, the bottom right gauge shows the cooler pressure, which indicates the pressure of the transmission fluid as it passes through the cooler to maintain optimal temperature levels.

Cooler Flow Rate:

Another key aspect to consider during the operational test is the cooler flow rate. It is important to ensure that the transmission fluid is flowing through the cooler at a sufficient rate to prevent overheating and ensure longevity. In this test, the cooler flow rate is well over one and a half gallons per minute, which is excellent and indicates efficient cooling of the transmission fluid.

Gear Ratio and Lockup:

On the main screen of the transmission panel, it is important to monitor the gear ratio and lockup status. The gear ratio on the right-hand side of the screen shows the transmission cycling in and out of lockup, which is crucial for optimizing fuel efficiency and overall performance. Additionally, monitoring the mainline pressure during lockup can help ensure that the transmission is operating smoothly and efficiently.

Shift Feel and Performance:

During the operational test, it is essential to assess the shift feel and overall performance of the transmission. In this test, the input, output, and cooler flow are all monitored to ensure that the transmission is shifting smoothly and efficiently. The fourth gear lockup test demonstrates the seamless engagement of lockup, with the cooler flow increasing as lockup is engaged, indicating optimal performance.


In conclusion, the operational test of the GearAR Performance transmission with invoice number 8334 4 l60e level four showcases outstanding performance and efficiency. The mainline pressure, cooler pressure, cooler flow rate, gear ratio, lockup engagement, and overall shift feel all demonstrate the high-quality construction and attention to detail that GearAR Performance is known for.
