Transgo A246E Shift Kit SK A246

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 and 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.
