Product Description
4L80E 4L85E Stator Support Bushing
DUE TO STATOR SHAFT VARIATIONS, IN SOME CASES IT MAY BE NECESSARY TO HONE THE BUSHING ID SLIGHTLY FOR PROPER FIT
Sonnax Part Number: 34016-W
NO TOOLING REQUIRED
GM 4L80-E and 4L85-E units may display no converter lockup or codes 68, 39, 1870 or P0741. Imbalance of torque converter clutch apply oil through the front stator support bushing contributes to this complaint. A journal clearance of .002" or more will generate sufficient leakage to cause lockup clutch slippage, causing the transmission to stay in third gear. Sonnax front stator support bushing 34016-W is designed to reduce leakage by minimizing journal clearance and also increasing journal length.
