Description
JuiceBox 1.0 Thermal Bypass for 2013-2018 Cummins with 68RFE or Aisin Transmission
The JuiceBox Thermal Bypass is engineered to provide critical protection for your transmission, eliminating a common risk point in 2013-2018 Cummins trucks. Constructed from a single piece of billet aluminum, this bypass unit is built for reliability and durability.
Say Goodbye to Stock Thermostat Issues
The OEM thermostatic block’s thermostat has a tendency to stick in the closed position, leading to excessive heat and potential transmission failure. By removing this thermostat, the JuiceBox Thermal Bypass ensures consistent cooling, helping you avoid the risk of premature transmission damage.
Low-Cost Insurance
For a fraction of the cost of a transmission repair, this bypass offers peace of mind that a small component won’t lead to catastrophic failure. The JuiceBox Thermal Bypass is the smart, affordable way to keep your transmission running strong.
Quick Installation
This upgrade installs in minutes with only minimal fluid loss—about half a quart or less. Designed for ease, it’s a quick improvement that adds valuable protection to your truck.
