Help: I have a 2004 civic Lx auto transmission. When cold started I can take the car a couple minutes down the road and then all of the sudden I lose all gears. Pull over, shut it off, start back up and can drive for another minute or so. Was low on fluid so I added until at the full line and it didn’t help. I checked the inner cooler line to see if maybe the inter filter was clogged but I had really good flow so that isn’t the issue. I drained the fluid and added new but that didn’t help either. I am lost on where to go from here and any suggestions or thoughts would be really appreciated.
