Having recently bought a 2010 Chevy Impala from Zoom Auto in Parsippany I quickly discovered a…read morebunch of hidden issues. No surprise there, the most challenging however were the oil leaks which quickly surfaced. It was diagnosed incorrectly 3x by auto repair shops such as MAVIS, Pep Boys and Firestone. MAVIS said it was from an oil plug washer and then Pep Boys wanted to replace the upper and lower intake manifold gaskets for $3300. and then Firestone said it was a transmission leak and sent me to Denville Transmission where Rob strongly recommended "SACKS SHELL" as he stated it was definitely an engine leak and not a transmission issue. From the start, I will tell you Bryan's confidence and honesty was impressive. He was assuring me that the owner, Fred, was honest and a straight shooter. He explained oil leaks are commonly coming from more than one source and the solution was likely going to be a process. After an inspection, Fred, the owner, felt the major leak was from the oil pan gasket so his expert mechanic Paul replaced same which slowed the leak down a lot. However, Fred was very scientific in his approach and I felt a partnership developed to be thorough and that a follow up was needed so we agreed to add new dye back into the engine oil to follow up for possibly more sources of the oil leakage. Sure enough it wasn't done leaking, this time it was revealed that the main rear engine seal was also leaking. His other expert mechanic, Lupe successfully did that job. You guessed it, there was still one more leak, it turned out to be a transmission cooler fitting on the transmission side which Fred was gracious enough not to charge me for that minor repair. The bottom line is that Fred has a great crew with tons of experience and everyone of them I found to be honest, responsive, reliable and professional in every way. Fred runs a terrific business and his prices are fair and reasonable. I plan on going there again and again... it was a refreshing and great experience. Finally, I found some good solid mechanics and a business owner who is fair and doesn't charge a fortune !!! " Gooooo Sack's Shell " !!!

Always prompt service I go there many times for a head light out or a brake light out they always…read moretake time out and do it quickly,very little waiting
