Also included is the Sonnax TCC Regulator Valve #77754 which requires a special reaming tool, that re-bores worn out aluminum 4L65E valve bodies which is an issue when time for a rebuild, and allows installation of this special high quality valve and sleeve, that lists for $50.00 dollars alone.  This problem is the NUMBER ONE most overlooked issue by other rebuilders. One indicator of this issue is the P1870 Code, if this valve is not installed, even after a rebuild transmission can be burnt out almost instantly do to the overheating, pressure loss, valve blow by and in turn causing clutch failure.
