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
