Transmission faults in this model and variant of the Captiva are common. Holden actually issued a service bulletin for affected cars to check and replace components including the torque converter, electro-hydraulic control components and speed sensors. Symptoms included a loss of drive, flaring or slipping between gears and gear selection problems. I’d say your problems fall within those boundaries. Have the vehicle scanned and if error code P0776 pops up, you have the same conditions that caused Holden to issue the service bulletin back in 2016. From there, talk to a Holden dealer as to what can be done about it.
