I had my dealer check my car one day and brought it back a week later after they had tools and parts in. Supra tech is on my team so I made sure it was a one day repair. Not a bad time to add an exhaust because that will need to be dropped for the repair
I've seen two at my dealership with this issue, sadly one being mine. Trans seal leaking down to the oil pan. Take it into the dealership, warranty repair
I tapped into the 4 wires on the bottle side. it was from left to right, ground, ground, DATA, power. Would recommend using a volt meter to recheck. Stay away from the one that reads 8V
New recall releasing on the Supra for "back up camera display-brightness and contrast setting". Looks like an issue for some people is going to be address here.
