Consumer Description

Had vehicles looked at twice and serviced once for the transmission slipping. No issues were found when looked at and light was deleted. Took to another mechanic who drained and refilled transmission. Transmission still slips after service. This happens at acceleration and continues til 3rd gears where it jerks in between gears. Stops while driving continuously, the starts up again if stopped for any reason.
