Advantage:
1, Temperature Reduction: The upgrade kit is designed to significantly lower the operating temperatures of your transmission, potentially by almost 20%. This reduction in temperature is crucial for the longevity and efficiency of the transmission system.
2, Preventing Overheating: By managing heat more effectively, the kit helps to prevent overheating, especially during periods of high load. Overheating can lead to a variety of transmission issues, so this feature is essential for maintaining the health of your vehicle's transmission.
3, Replacement of Defective Parts: If your current cooler flow bypass valve kit is broken, this upgrade kit serves as a high-quality replacement. It ensures that the transmission cooler functions properly, which is vital for the overall performance of your vehicle.
4, Continuous Coolant Flow: The kit ensures a steady flow of coolant to the transmission system at all times. This continuous flow is essential for keeping the transmission components adequately lubricated and cooled.
5, Transmission Cooling System Efficiency: By upgrading to this kit, you enhance the efficiency of your transmission cooling system. This can lead to improved performance and a reduced risk of transmission failure due to heat-related issues.

Installed it today and drove for 2 hours, works absolutely perfect. My transmission never got above 166 while driving, 180 while sitting idling. Used to go 230 within 20 mins. Just as good as the Shift Technology Superior Solutions brand which costs $40+ for the exact same thing. I don't understand the other reviewer complaining about no instructions, those instructions are everywhere on Google just look it up, but you deduct two stars because it didn't come with instructions? Dude it will save your transmission for $14! Just don't over-torque that bolt when you put the tbv block back on, 16 ft/lb and no more, the threads are aluminum!

No instructions. The manufacturing and finish of this is just OK. It could be better. Not polished at all. At least to no burrs or rough edges. I’m going to order another kit and if it’s in better condition, I’ll just install that before trusting this kit.
