- Updated TransGo Actuator Feed Limit Valve
Also included is the TransGo Actuator Feed Limit Valve which requires a special reaming tool, that re-bores worn out aluminum 4L80E valve bodies which is typically an issue when time for a rebuild, and allows installation of this special high quality valve. This problem is the NUMBER ONE most overlooked issue by other re-builders. One indicator of this issue is the 2nd gear starts, 3rd neutral condition, no 4th gear, codes 68, 85, 86, and 87 and direct clutch breakage. The OEM actuator feed limit (AFL) valve has a large reaction area and is greatly affected by side loading, which wears the valve body bore. The EPC solenoid oscillates the torque signal and AFL oil, which increases valve action. As bore wear increases, oil pressure is reduced to the shift solenoids, which causes solenoid and ratio codes. The same AFL oil loss results in lower line pressure. If this valve is not installed, even after a rebuild transmission can have these issues and can lead to transmission failure 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. - Superior Shift Correction Package
This shift correction kit corrects with these common issues: Runaway high pressure, Erratic pressure rise, Converter lock-up shudder. Inconsistent shift feel, Shift solenoid filter blow-out, and Premature unit failure
A complete pressure regulator valve train is supplied in the 4L80-E kit. This corrects Fail-safe, runaway high pressure that will crack the case if not corrected. The PR valve train supplied in this Shift Correction Package will stop runaway high pressure before it happens.
