A shop that specializes in euro cars would probably charge you more. It's a GM transmission. A shop should easily check fluid level on a lift with a scanner. A scanner is necessary to know oil temperature. I paid a local shop last year to change the transfer case oil, trans filter, and oil for $125. A few discounts were applied though.
