Common concerns with this transmission are TCC shudder, rough coast down shifts, gear ratio error and solenoid performance codes. Firstly, these complaints are the result of the wear in the pressure regulator (PR) valve bore and the pressure regulator valve balance bushing. Secondly, the torque converter clutch regulator valve design and calibration were in dire need of an upgrade to address the TCC shudder complaint.

The kit includes a hardened steel drop-in two-piece pressure regulator valve and a redesigned TCC regulator valves for a quick no-hassle install. Our drop in valves require no reaming or tooling.

Both the redesigned drop-in steel two-piece PR valve and TCC regulator valve feature longer lands which restores the hydraulic integrity of the circuit by utilizing previously unused and therefore unworn areas of their bore. Furthermore, the longer lands increase bore longevity by redistributing the load over a greater surface area. The kit also includes new rubber dampener inserts that flatten out over time and new wire retainer clips to replace the occasional broken one.

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.
