possible reason of jerk from P to R only in Automatic Corolla GLI 2015?
Recently Tx oil was flushed with Kixx DX-III (a compatible oil of Toyota Standard ATF T-IV). So there is no issue of compatibility.
Initially Tx fluid was not changed till 70K ODO by previous owner. Jerking was also observed before the flushing. Tx fluid pressure was improved from 1.7 MPa to 3.0 MPa after flushing but jerk is still there as soon as Gear shift from P to R or From N to R. This happen only in reverse(R).
any solution to avoid jerk? as I don't want to perform the valve body service at this stage, as I have serious doubts of getting it worse after opening as it is a highly sophisticated part.
