Has anyone replaced this seal.My ml 320 is a 2002 with 102,000 but had been leaking for a little while.Looks like the transmission has to come out and so I had an Indy shop look $ 1353 .00 with tax wow.This job looks to hard to do on my back any suggestions will be appreciated as the trans needs to be removed.I have liked the looks of the ml but always felt from interior issues to now this it was an inferior product
