People that know what they are doing. No hacks. Good prices.

Funny reading all these reviews for myself. A couple of years ago I had theminstall a PPE in my Duramax. The truck took a week longer than i was told.Driving the truck getting onto the highway the truck would exelorate great and then slam down another gear and go into limp mode. My transmissionnow chatters at around 50mph. Brought the truck back to them. There solution was dont use the truck on the 5 setting. the lower settings are better for good gas mileage. Why by a performance chip in?

Your search is over. Assuming youre looking for a high quality, 100% trustworthy garage, look no further than On The Line. Of course, Id like to keep this secret for myself, but when you meet the folks who accurately diagnose your problem, followed up by timely, solid repairs ( or customizations), you will, like me, want the very best for those guys. I genuinely feel good paying On The Line my hard earned money. Have you ever gotten that type of feeling from a garage? I drive -- and sometimes tow -- over 30 minutes just to get to them...and look forward to it knowing Ill be with great people who will make my problems go away. My 2003 Turbo Cummins (280K) continues to run like a beast thanks to them. Again, look no further if you seek a mechanical Nirvana.

I Bought A Used Dodge Pickup Truck For Sale In Front Of Joes ON THE LINE DIESEL Repair Shop, With All The Paperwork On A Rebuilt Transmission, I Drove The Truck Back And Forth To BOSTON As My Daily Driver. Almost 30 Days In, The Trans Overdrive Casing Cracked Open. I Didnt know What To Do. Joes Told Me To Tow The Truck Back To His Shop, And Stood Behind His GOOD WORD And Fixed My TRANSMISSION And Made It Right. THANK YOU JOE AND YOUR EMPLOYEES FOR BEING 100 % HONEST AND DOING 1ST CLASS AND TOP NOTCH WORK AND MAKING MY CHRISTMAS A WHOLE LOT BETTER 😊😊😊 I WILL BE A REPEAT CUSTOMER FOR SURE, AND WOULD STRONGLY SUGGEST BRINGING ANY OF YOUR VEHICLES TO JOES ON THE LINE DIESEL REPAIR SHOP, THANKS GUYS 😎😎

I wouldnt bring my Duramax anywhere else.. Proper diagnostics and always done right. From Diesels to Gas if youre looking for a upfront no BS, honest mechanic to get you back on the road. Look no more. On The Line is above the grade hands down.
