Toyota/Lexus vehicles with listed transmissions may have harsh or slipping shifts and loss of engine braking in D2 range. This is often caused by accumulator piston bore wear that allows leakage in the B2 circuit. In extreme cases, the pistons can become jammed in the bores. Reconditioning the bores and installing Sonnax oversized B2 accumulator pistons 147741-13 will restablishes control of the B2 circuit to restore normal shift operation and feel.
