This upgrade lowers engine RPM's and temp. Your 700R4 transmission will also experience a reduction in thermal viscosity and wear. In addition the lockup will make a noticeable improvement with your vehicles fuel economy.

Governor Upgrade
There have been many reports of issues with this transmissions factory supplied governor. The most common of these governor problems is that the internal gears had a tendency to stick and the springs were notorious for popping out of place. We have upgraded both the gears and springs to solve these long standing issues.

Shift Kit & 3-4 Clutches

Leaking fluids is always a serious problem with transmissions the the 4L60 is no exception in fact they are notorious for hemorrhaging oils after extended use. Our seal and gaskets have been upgraded to the latest in molecularly bonded materials. They are rated and tested for their ability to withhold the maximum pressure the 700R4 transmission can build.
