Next, we re-inspect the front planetary assembles – measuring clearances and making sure everything is within our own rigid specifications before installing it and inserting the output shaft. No matter how hard you beat on it, THIS SHELL DOES NOT BREAK! The GFX Shell is able to withstand the rigors of the street, the strip, or the mud whichever is your pleasure. We then replace the sun shell with a new heavy duty unit The GFX Shell, which far exceeds the factory component.

Simply put, these planetary assemblies with good lube DO NOT EASILY FAIL even in the most demanding environments. When you see one of these with a damaged rear planetary, it will almost always be accompanied by the blue-black signs of excessive heat. Their failure is almost exclusively due to a lack of lubrication. In fact, contrary to common opinion, the rear planetary assembly in these transmissions is not, in any way, weak by design. This is a huge improvement and virtually eliminates one of the most common points of failure for this type of transmission. This allows oil to escape from between the bearing and the gear it rests against, feeding additional lube to the planetary gears. Next, the sun gear is inspected and modified to improve lubrication to the rear planetary assembly. In addition, dual bushings are installed in the rear sun gear to handle the extra weight of the beast sun shell. At this time the center support and sprag (one way roller) are installed after being inspected for stress cracks and damage. The rear planetary assembly and bearings are meticulously inspected, then assembled into the case along with heavy duty reverse friction and steel plates. The seals in the case are then replaced and assembly begins. The case is specially prepared and a coating of and heavy duty, heat resistant, oil based enamel is baked on, creating a hard and durable glossy finish. The case and hard parts are cleaned thoroughly and re-inspected for cracks, wear, or other damage before we begin.

We believe you will not find a better performance transmission anywhere!īelow are the details of our Pro Race (LEVEL-2) built transmission.įirst, each core transmission is disassembled and carefully inspected. We incorporate all the updates and modifications to compensate for the problems and issues they were born with from the factory. These transmissions are tough and built to handle whatever you dish out.

Our Pro Race Series transmission is the finest built street/race automatic transmission in the industry. Finally, the difference in driving characteristics once the kit is installed is remarkable.Description Pro Race Series (Level 2) 4L60EĪ Core is Required for all C5 Corvette Builds

The kit also provides TCC regulator valve component options that will work with vehicles with or without active fuel management (AFM). Furthermore, the included drop-in USA-made TCC isolator and regulator valve features longer lands which restores the hydraulic integrity of the circuit by utilizing previously unused and therefore unworn areas of their bore. These changes work in concert with a slight increase in line pressure to greatly improve the overall durability and shift feel of the transmissions. It includes components as well as modifications that recalibrates the entire accumulation system. The kit includes valve body, servo, pump and accumulator components and modifications designed to deliver increased durability while providing short smooth shifts as well as a more efficient TCC apply. The 3-4 clutch plate failure as well as the 2-3 flare up complaints are caused by an inconsistent pressure boost and poor overall calibration of the shift accumulation system.

The TCC slip code leads to the harsh 1-2 upshift as the ECM recognized the TCC slip and commands high line pressure to avoid further TCC slippage and damage. The torque converter clutch regulator valve bore is very prone to wear causing the TCC slip complaints and related code. Common complaints on this transmission are TCC slip or shudder, code P1870 or P0894, harsh 1-2 shift, double bump shifts, 2-3 flare up, burnt 3-4 clutch plates as well as inconsistent pressure boost problems.
