Engine and Transmission Exchange, Inc

I found them through AAA when I moved to Milwaukee in 2010 and have been going for routine and non-routine maintenance at least 4 times a year since. They do good work, they communicate well, they are priced fair and they go above and beyond.

One year I was in an accident and brought my car in to get the steering and suspension realigned. When I picked it up they had popped out the dent in the bumper purely out of goodwill given they aren't a body shop and it was free of charge.

If the check engine light is on and the diagnostic is something silly like a loose gas cap they will turn off the light and wave the diagnostic fee. If it is something that needs to be repaired the $90 price of the diagnostic is applied towards the repair.  

Given all the times I've brought my car to them I've only had one incident where some lug nuts were loose after a tire rotation. They were immediately apologetic and reimbursed me.

I can't say enough good things about this place. When you walk in you will see many hand written thank you notes from other equally grateful and happy customers. When places like Jiffy Lube are scamming customers by cutting corners and selling unnecessary services it feels good to have a trustworthy mechanic.
