OUCH that is pretty ridiculous pricing!! Im not sure what you were told by as Chris mentioned above the part itself isnt that expensive but unfortunately is is literally one of the last parts that is taken out of the transmission case when taking the trans apart which means a complete rebuild or replacement just as you were given the option. $7000 is the most insane BS price I have ever heard and either they said it so you wouldnt possibly take it or as you mention being of the female gender sometimes makes salesman think they can take advantage of the situation. If it is under warranty then it better get taken care of and I would raise #$(*@%%%^%# if it is not covered!
