hey guys, me again :D
so we have successfully replaced the auto trans fluid, and all works great as expected.
there's a confusing catch. i call it olfactory reverse indicator.

every time i engage reverse, within seconds i actually smell the oil. everything works, though. we followed the instructions as best we could, the amounts of oil we handled was as expected, and i cannot find oil pools under where i park.

i did some half-scientific fact-finding, and it only happens with reverse.

has anybody come across this weird phenomenon before?

cheers from the alps

reverse spins the opposite way, could be the oil seals can't take going backwards and then leak
