Sonnax GM 4L80E TCC Regulator Valve 4L80-E Automatic Transmission
OPT Product Code: SNX-34994-01K$37.70
Product Details
Some vehicles with a 4L80-E transmission may exhibit the following problems: converter shudder, burned converters, no TCC clutch apply, and/or code 68/39 or P1870/P0741. Often these complaints can be caused by the constant oscillation of the steel TCC regulator apply valve wearing the aluminum bore, resulting in a loss of converter apply oil pressure. Sonnax now offers a replacement TCC regulator apply valve kit 34994-01K that will prevent valve-bore related problems.
