Hi all. I noticed my transmission has been slow to upshift and seems to get stuck on 3rd gear. Also erratic shifting/jerkiness. Obd2 scanner showed a gearbox code. I saw this leaking was wondering if it could be a mechatronic sleeve leak? What do you guys think

 

Not likely The sleeve as then oil would be at rear end of tranny, this looks like you need to replace the gasket, assuming your pan/filter has not been replaced recently get pan replaced comes with the gasket.

 

Looks like the pictures are of the back end of the trans. Mech sleeve is at right rear, so a leak there could wick down to the pan, then forward. OP, look up at right rear of the trans.
