Transmission repair service near Princeton, NJ

If you live in central/south jersey (or a reasonable distance).  Owns a car you care about and/or plan to own for years. Don't want to pay dealership price for the same, and in most cases better customer and car service.  And/or need a knowledgeable, trustworthy, dependable, courteous and cost-effective auto technician...YOU SHOULD KNOW UNION LINE GARAGE IN HOPEWELL.   These guys are one of the best in the business. I have so much confidence in them that 'twas it not for legal reasons, and the size of my bank account...I would offer to pay for your repairs at another shop if you can prove said shop provided better workmanship, price and service than Union Line Garage. 

This is the best mechanic shop I have been to. They are kind, helpful, and reasonable. They always try to fit me in for last minute oil changes and honor my coupons even when I forget to bring them. What you see is what you get, I love that.

Sterling and expert service. My '05 Corolla with 315k miles, purrs like a kitten thanks to John and his team at Motorworks. Got an oil change, two new tires and front end alignment. Car is running great. Thanks!

TERRIBLE SERVICE! It took 12 days to have my transmission replaced. Every person I talked to gave me the same exact excuse..."I've only been working here a few days". They must turn over the staff once a week. Also, BEWARE: they don't do the work on premises. They kept feeding me excuses that they sent out the transmission and they had no control when it was delivered back, etc, etc. The final straw was when they GUARANTEED I would have my car back on a Tuesday. I took off work for the day and arranged for a ride to get my car (was told it would be ready around 2-2:30). I received a call at noon to tell me it would be another day! The consolation...they invited me to come down and "look" at my transmission if I wanted to. Finally, I was called at 4pm the next day and left a message that my car was ready BUT they were closing the shop early and if I wanted my car I had to be there before 5pm (30 minutes prior to advertised closing time). They also would not let me use the coupon I obtained from the website and informed them I would be using prior to service starting. This place is unprofessional, slow, and rude. And they cost the same as a dealer. Save yourself a hassle and go somewhere else. AND, don’t believe Craig when he tells you what day your car will be ready. 12 days for a repair is ridiculous. ***Addendum*** a few days later I notice a sticker in my car from Haldeman Nissan on Rt 33. I then received an email from Haldeman thanking me for my service. I was not happy with Haldeman in the past and was purposely avoiding them. AAMCO not only sent my transmission to Haldeman without telling me BUT ALSO GAVE THEM MY EMAIL ADDRESS. WTF!?!?
