Okay, I did it and now the flashing/blinking AT Oil Temp light is very concerning. Is that caused by such improper towing? If so, what would I expect to happen or to have fixed?
Crucial is for you to confirm if it has a manual or auto transmission - I know you mention the AT light but that may just be the label from the owner's manual.
Most manual transmissions can be towed like that for at least 5 miles and maybe more, some trucks / cars have to have the propshaft removed first
An auto box however, is a different proposition - there is usually an oil pump that is driven by the engine and if this pump is not providing oil, then the bearings and mechanisms in the auto box can easily be damaged through lack of lubrication.
It will need checking as the damage can be severe, it will reduce the lifespan of the box and will probably be expensive.
On your 2014 Outback, you have a CVT transmission. The flashing light means that the car is not happy with the transmission for some reason.
If you're still under 100,000 miles, the transmission should still be under warranty. Take it to a Subaru dealer to get the code read. If you're lucky, it's a simple fix or under warranty. If not..
It’s a 2.5l CVT over 110k. The AT Oil Temp light blinks 8 times rapidly and have not able to decode. Took to a shop to diagnose with TCM scan, no code or was previously reset. Told to continue driving if any light comes on. Anyone with blinking codes would help.
