This Toyota A246E SHIFT KIT® Valve Body Repair Kit fits 2003 to 2008 model year A246E in Toyota Matrix with the 1.8L 130 horsepower engine, 2003 to 2008 A245E with EPC solenoid in Toyota Corolla with 1.8L engine as well as 2003 to 2008 two-wheel drive A246E in Pontiac Vibe. Common complaints with those transmissions are shuttle shifts, bind-up or flare on the 2-3 shift, slips with throttle in 3rd or 4th, kills engine at a stop as well as TCC slip codes.
The first area of concern leading to the TCC complaints is a worn-out TCC relay boost valve and bushing. When the TCC relay boost valve and bushing wear out, lock-up control and overheating complaints occurs.
The other area of concern is a worn-out solenoid modulator valve bore. The purpose of solenoid modulator valve is to limit the pressure going to solenoids, just like an AFL valve or solenoid pressure regulator valve does on other units. The modulating valve and spring are calibrated to prevent solenoid feed pressure from exceeding a predetermined PSI, no matter what main line pressure is. This is necessary to prevent more fluid from being fed to the solenoids than they can effectively regulate and to limit what max line pressure output is. If the pressure feeding the solenoids is too high or too low, output will also be too high or too low. Consequently, shift quality complaints, solenoid performance and gear ratio codes can occur along with low or high main line pressure.
Features & Benefits:
The kit includes a drop-in USA-made hardened steel TCC relay boost valve and bushing restores the hydraulic circuit integrity. Similarly, a new redesigned drop-in solenoid modulator valve system does not require any tooling. The furnished bushing and valve will restore the solenoid modulator valve function using existing worn bore.
Corrects/Prevents/Reduces:
Shuttle shifts, bind-up or flare on the 2-3 shift
Slips with throttle in 3rd and/or 4th
Kills engine at a stop
TCC Slip codes
Includes:
USA-made hardened steel TCC relay boost valve and bushing

TransGo Shift Kit vs. Reprogramming Kit
Shift Kit® -- DESIGNED FOR DURABILITY
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.
Reprogramming Kit -- ENGINEERED FOR PERFORMANCE
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.
What is a Shift Kit?
TransGo Shift Kit® valve body repair kits are a combination of new and re-engineered components that are primarily installed in the valve body, but sometimes the pump or even in the transmission itself. These kits solve a variety of inherent problems and weaknesses that differ by transmission model, including usual warp and wear, often allowing a higher mileage transmission to work better than a new one. Typical components of a valve body repair kit include springs, valves, check balls, gaskets, separator plates, etc.
