CNC FABRICATION 425033 4R100 TRANSMISSION COOLER BYPASS FITTINGS FOR 1999-2003 FORD SUPERDUTY WITH 7.3L POWERSTROKE ENGINE

Introducing the latest upgrade for your 98.5-03 7.3L Ford Powerstroke.  CNC Fabrication 4R100 transmission cooler bypass fittings. These fittings have been designed to replace your factory bypass tube that is known to fail and cause overheating issues in your transmission.

Crafted from high-quality 12L-14 carbon steel, these fittings are built to withstand extreme conditions and ensure long-lasting performance. The black zinc chromate plating adds an extra layer of protection against corrosion, making them a reliable choice for any truck owner.

One of the key features of these fittings is their longer thread count, which provides superior thread engagement and prevents stripping out of the threads inside the transmission case. This ensures a secure fit and eliminates the risk of leaks or damage.

We have also installed new Viton O-rings inside the fittings. These premium quality O-rings are known for their exceptional resistance to heat, chemicals, and other harsh substances, making them ideal for use in automotive applications.

Don't let a faulty bypass tube compromise the performance and longevity of your transmission.  Trust CNC Fabrication for top-quality aftermarket parts that deliver exceptional results every time.
