How much should I be paying?

Well i'm goin to get my Tranny serviced next week, and i'm just wondering how much the going rate for this stuff normaly is... They will be droping the pan, draining/replacing both fluids, and replacing the filter.. I know this shop does good work he's been around forever, and the company i work for goes to him when need be.... I'm getting charged $80-$100... I'm thinking its pretty fair...

Considering the labor involved and parts, I'd say what you're geting charged is fair.
