As a result, with a more aggressive pressure curve and MAX main line set to 185 psi in all forward gears, the kit provides as much as 75% increase in torque capacity for all the clutch elements including the TCC clutch. This kit includes our patent-pending triple valve body separator plate which allows you to achieve TCC operation in all forward gears in 1st to 4th on 46-47 RE type valve bodies.

Achieving TCC in the lower gears requires additional electronic control of the TCC solenoid (not furnished).

Keeping the shift timing at the OE RPM's for the optimal engine power curve brings a whole new driving experience to the truck. Therefore, the shifts are short, clean and flat out hold as the power is rolled on. We feel this kit is the Holy Grail of 47-48RE valve body kits on the market, you are going love it!

Lastly, you can install this kit with the transmission in the truck. On the other hand, there are internal sealing rings furnished in the kit if the transmission is on the bench for overhaul.

TransGo Shift Kit® valve body repair kits correct, prevent and reduce multiple transmission problems such as shift irregularities and durability issues. These kits are designed for normal everyday use and light duty towing.

TransGo Reprogramming Kit™ valve body performance kits are made for Heavy Duty and/or Performance applications, and include additional features such as:

• Gear Command™: Allows full control of downshifting and will hold any gear to any RPM. Retains automatic up shifts in the drive position. Certain units allow manual up shifts on driver command.
• Manual Shift Control: This feature fully converts the valve body to manual/stick shift operation – no automatic shifts. Most Manual Shift Control kits also allow you the ability to easily convert back to automatic.
• Tuneless: Patent-pending internal calibration technology “tuneless” allows install without the need for additional transmission tuning software or programmers.
