NO.21 EXCESSIVE SHIFT SHOCK ON TORQUE CONVERTER CLUTCH (TCC)

BHE050301026W26

21 | Excessive shift shock on torque converter clutch (TCC)
DESCRIPTION | • Strong shock is felt when TCC is engaged.
POSSIBLE CAUSE | • Incorrect characteristics of input signal or malfunction of TCC piston pressure adjustment (when there is open or short circuit, shock does not occur because fail-safe prevents TCC operation.) Inspection procedure is basically the same as No.14 "TORQUE CONVERTER CLUTCH (TCC) NON-OPERATION".
