I would give J & J Auto on Whipple in Union City a 5 Star X 10!
Juan is professional & keeps his customers updated & informed.
I have an extended warranty on my 2014 Nissan Murano. I took my car to Juan for analysis on my transmission.
I had read online that some of the Nissan Muranos have had CVD transmission issues.
I make sure I have all preventative maintenance on my car.
I left my car for Juan to take it for a test drive expecting the usual diagnostic tool but instead he left with a TouchPad device.
The TouchPad device detected issues & showed the error codes with my transmission.
Juan updated me that the transmission would need to be replaced with a transmission from Nissan dealer.

Juan then called the extended warranty company, faxed them the computer diagnostic findings & had everything authorized in record time.

There was a 2 - 3 week back order on the transmission, I took the car back home & as soon as the transmission came in Juan called me to bring the car in.
Juan explained the process & timeline which he met as discussed.
Juan had me bring my car back in a week later to check everything.
I am happy to say that my car drives like when I bought her & I am so relieved that I found Juan at J & J Auto in Union City!

Juan is an excellent mechanic & his diagnostic tool is superior to any device I have seen!

I highly recommend Juan & will continue to take my car to him for excellent Customer Service & mechanical expertise!
