## Description

Application:Works on 2010-2012 Ram 6.7 Cummins Diesel 68RFE.A Must Have Tool:1. 87% increase in cooler flow due to the elimination of the orifice bottleneck located in the factory part.2. There is no longer a thermal controlled bypass valve which can fail and cause lack of cooler flow and complete transmission destruction3. Instead of closing off cooler flow when the transmission is cold and making your transmission generate unneeded heat that is hard to shed later;our bypass allows your cooler to immediately begin cooling your transmission and not waiting for it to get hot, just to try to cool it later.4. You cannot properly flush your cooler lines without the aid of a hot flush machine that can get hot enough to open the bypass valve up.With our bypass upgrade you can use room temperature fluid to clean out your cooler anytime you wish without any special tools.5. This is a direct bolt-in replacement for the factory ones. No lines are cut, nothing is altered. Simply disconnect your old lines and install them into our new bypass.Satisfaction Guarantee: If you're not satisfied with the tool, simply return it for a full refund in 30 days or get a replacement during 1 year warranty via our customer service.

## Features

- Application – Perfectly fits for 2010-2012 Ram 6.7 Cummins Diesel 68RFE.
- Replacement – Our 68RFE Transmission Cooler Thermostatic Bypass Upgrade is a direct bolt-in replacement. No lines to cut, nothing will be altered. Simply disconnect your old lines and install them into our new bypass.
- Upgrade – Instead of closing off cooler flow when the transmission is cold and making your transmission generate unneeded heat that is hard to shed later; our bypass allows your cooler to immediately begin cooling your transmission and not waiting for it to get hot, just to try to cool it later.
- A Must Have – 87% increase in cooler flow due to the elimination of the orifice bottleneck located in the factory part. There is no longer a thermal controlled bypass valve which can fail and cause lack of cooler flow and complete transmission destruction.

However, with our bypass upgrade now you can use room temperature fluid to clean out your cooler anytime you like without any special tools.
