Chevy Silverado Transmission

One of the most common 4L60E trouble codes is the dreaded 1870: Transmission Slippage. This occurs when the OEM Torque Converter Clutch (TCC) regulator valve's bore wears out in the valve body. As the TCC regulates torque converter clutch pressure, a worn bore causes a leak in the apply pressure circuit and allows the clutch to start slipping, ultimately resulting in converter clutch failure. FLT replaces the OEM TCC regulator (top) with the TransGo part on the bottom, designed to prevent and compensate for bore wear.
