This problem is the number one most overlooked issue by other re-builders. One indicator of this issue is the p1870 code. If this valve is not installed, even after a rebuild transmission can become overheated and as a result can burn up quickly do to torque converter slippage, caused by the badly worn valve body casting in the converter clutch regulator valve bore. The oem tcc valve on 4l60-e units wears the bore, creating pressure leaks that affect performance.

Common issues with this are overheated converters, harsh 1-2 shifts, burned 3-4 clutches, and failed lock up converter clutch.
