Features and benefits:

This TransGo SHIFT KIT® Valve Body Repair Kit includes an oversized USA-made steel reducing valve to completely restore the hydraulic circuit integrity. In order to install this valve, the bore must first be reamed oversized. If you don’t already have the reamer and guides, you will also need TransGo part # A4A6-RV-TK. On the other hand, the new drop-in torque converter regulator valve system does not require any tooling. The furnished bushing, valve, spring and end plug, will restore the torque converter regulator function using existing worn bore.

Corrects/Prevents/Reduces:

• 2-3 flare
• Direct clutch failure
• Erratic shifting complaints
• Flares or neutrals on shifts
• Gear ratio or solenoid performance codes
• Delayed engagements

 Includes:

• Oversized USA-made hardened steel reducing valve
• Drop-in USA-made steel converter regulator bushing
• Drop-in USA-made hardened steel converter regulator valve
• Converter limit regulator spring
• Steel converter regulator valve end plug

This A6MF SHIFT KIT® Valve Body Repair Kit fits 2009 and newer Hyundai and Kia vehicles with the A6MF1/2, A6GF1, A6LF1/2/3, as well as 2013-2016 Jeep and 2012-2016 Dodge vehicles with the 6F24 transmission. Common complaints with this transmission are brutal 6-4 kick-down bang, erratic shifting, flares or neutrals during up and downshifts. It may also set gear ratio and solenoid performance codes and have TCC shudder or slip complains and codes.

This transmission uses two reducing valves in the valve body that often severely wear out their bores. Reducing valve #1 regulates the pressure going to the two ON/OFF solenoids as well as the OD, 2-6, 3-5-R and UD pressure switch valves. Reducing valve #2 regulates the pressure going to the six PWM solenoids.

The purpose of the reducing valves is to limit the pressure going to the solenoids. The spring is 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 limit what max line pressure output is. If the pressure feeding the solenoids is too high or too low, their output will also be too high or too low. As a result, shift quality complaints and codes can occur along with low or high main line pressure.

The other issue has to do with the TCC control valve bushing wear. Consequently, the computer loses the ability to control the lock-up clutch apply rate properly due to the loss of TCC apply pressure.
