The service went well today. You get to talk to the person working on your car, which in my case was the Carolyn who started the business.
The shop is clean and well-organized. They use all genuine parts and even stock the correct washers for drain plugs. All of the shop's operations and the building design itself were designed with sustainability in mind. I was able to talk to the mechanic while she was working on the car and it was clear that she knew these cars very, very well.
The cost of the transaxle drain and refill was $98 total. $60 for labor (1/2 hr), $32 for fluid ($8/qt), $2 for washers (one for drain and one for fill), and the rest was for taxes and disposal fees. Dealers around here charge $11/qt for ATF-WS, but I usually am able to get it for $8/qt. So, there was very little parts mark-up for my service.
There was however, a slight misunderstanding regarding the price that I was quoted for the service by e-mail. I was quoted $80, but that was actually the price for their taxi program. So to make up for that, they did my oil change for no charge-- I already had the oil and filter with me. Since I originally planned to spend the $80 + $20 (or so) for the oil change labor anyway, it worked out in the end and was not a big deal at all.
Overall, I would definitely return for future service. They are familiar with the cars, they do the job correctly, and do it efficiently.
