This vehicle, an automatic Subaru, was having intermittent gear change issues so we suggested removing the sump on the gearbox to inspect the automatic gear oil, cleaning out any “sludge”and then refilling with quality gear oil.
Unfortunately, removing the sump revealed the fault as something was breaking down inside the box.
The only solution was to send the vehicle to an experienced gearbox specialist who stated that, if the issue had been left, the final bill would have been much worse.
