The couple people I spoke to here were very nice, answered all my questions, gave me time to think over my options, and kindly gave my keys to a tow truck driver for me when I decided to take it elsewhere.
My car was originally towed here after it just stopped accelerating while I was driving. It was a Saturday afternoon and nowhere nearby was open but Precision, and they said I could bring it by for them to look at Monday. I called them just before closing time on Monday since I hadn't heard back. The guy said my transmission needed rebuilt and quoted $6500 + tax, or he could call around for a used one to replace it with (which Google tells me is not a wise investment). I said I needed time to think about it, so I called about a dozen other shops.
To my surprise, even the dealerships were only quoting $5000, a couple transmission shops were $4300-$4700. I ended up going with Transmission Sales and Service in Tacoma who did it for $3500 + tax - and my experience there was great. My fiancé gets his oil changed at Precision, and likes them for that so maybe just call around if you have a big repair. That $3000 made a huge difference for me and my emergency fund. They also charged me a $173.09 diagnostic fee. I've never been charged a diagnostic fee at any other mechanic I've been to (though I usually go to small 1-man shops rather than chains), so that really added salt to the wound on what was already a very stressful event. Overall, I don't feel confident that this is the best place to spend my money unfortunately.
