Transmission Repair near Mahwah, NJ

“Amazing family-owned business. Bought a Jeep Wrangler sight unseen. Realized when it arrived something was off (A LOT). Took it to the folks at Total who went out of their way to help. Was conscious of my budget and really tried to work with me while making sure the Jeep was safe to drive. If you own a Jeep that needs work or mods and live in NJ/NY etc these are the people you need to go to.”

“This place was fantastic! I blew a tire on my travel trailer on the Thruway And I was towed to Mahwah To a tire place that was supposed to have what I needed. When we got there, they didn’t and I called at least a dozen local tire places with zero success. I called this place and the guy was so helpful although he did not have the exact tire I needed. He was able to sell me another one that was very similar. I ended up buying two which meant I needed to drive back to my trailer. Install the one tire bring the trailer back to him to install the second tire. The place stayed open an hour later for a complete stranger and saved my family vacation!!!! Had it not been for them my travel Trailer would have been sitting in the middle of a grocery store parking lot certainly overnight. My food would have spoiled and we never would have been able to get back on the road the same evening. Good people still exist! Luckily I live pretty local and will be using them from here on out!”

“The shop is run by Serge — hands down one of the most technically gifted mechanics I’ve met.
I first met him back in the early Audi tuning days, when he was one of the first guys to both turbocharge and supercharge a B6/B7 A4. This was before off-the-shelf everything. Back then, he was building cars properly — custom hardware, custom calibration, tuning on Maestro when the Audi scene still required actual understanding of ME7 logic, load modeling, fueling strategies, and knock control instead of flashing files and hoping for the best.
From there it escalated quickly.
Tesla drivetrain swaps into Audi chassis (including an S5) — full custom wiring, CAN integration, and making it all communicate cleanly with Audi MMI, cluster logic, and factory controls. That alone weeds out 99% of shops.
On the ICE side, he’s built performance engines from the block up, handled motor swaps, full rebuilds, and bespoke turbo systems, and fabricated his own solutions when parts didn’t exist. His TIG welding work on custom turbo manifolds and exhaust setups is the kind of stuff you normally only see in high-end motorsport or boutique race shops.
What really separates Serge, though, is diagnostics.
He has an almost unfair ability to trace electrical faults, drivability issues, and intermittent problems that other shops miss entirely. If ten mechanics couldn’t find it, he usually does — methodically, logically, without guessing. It’s not magic; it’s deep systems-level understanding.
I’ve trusted him with six Audis over more than 12 years — everything from routine maintenance to engine swaps, rebuilds, suspension work, and custom performance setups. Every job was done clean, properly torqued, correctly routed, no shortcuts, no “that’s good enough” mentality.
On top of all that:
Work is clean and documented
Attention to small details most people overlook
Pricing is fair for the level of work
And he’s genuinely enjoyable to deal with — no ego, no bullshit
At this point he’s deep into the supercar world, but the mindset hasn’t changed. Same precision, same standards.
Top-tier mechanic.
Top-tier owner.
The kind of shop you don’t replace once you find it.

P.S. last car he worked on (4.0t twin turbo S6) made 923whp on e40 on a mustang dyno.”

“I’ve had work done on my bmw and jeep here. Really good guys, always tell you the full cost before you pay and very fair. They don’t make you sit around, they do the work efficiently and give normal quotes.”

“Courteous and professional service.. I have been a customer for several years and have always appreciated the honest, problem solving advice I get from Bob Crevaux’s Wayne Auto Works. I am a very satisfied customer!”

“Deo is the best. He can fix almost anything on the car, even If it’s not under the hood. He is very trustworthy, efficient and very fair with his prices. I wouldn’t go any place else in this area. I have known Deo over 25 years.”

“Chrysler replaced my transmission twice. When it broke the third time, I brought it to Barrett. Rich called me at the end of everyday giving me updates. He even stayed late one night to get it done becauce we were without a car for 2 weeks waiting for chrysler. Chrysler has still not returned any of our calls.
Rich is honest and informative.
Lets face it, nobody wants to replace their trans but if you have to go here.”

“I can’t recommend Checkered Flag Auto enough. My car broke down locally and they truly helped me out in an emergency situation. They were able to diagnose and fix the issue by the very next day, which was such a relief.

What stood out most was how honest, kind, and reasonable they were with pricing. As a woman, it can sometimes feel uncomfortable dealing with mechanics, but I felt completely comfortable and respected here from start to finish. Everyone was friendly, transparent, and never made me feel pressured or taken advantage of.

I’m very grateful for their help and would absolutely use them again in the future.”

“Jonathan and team are so helpful, so accommodating, and very informative. They explain things really well, their prices are reasonable, and they do great work. When my tire pressure light came on right after the services, Jonathan was happy to check and fill my tires for me. I’ve recommended them to a neighbor as well who was also very pleased with their services. Thanks guys!”

“John helped me through the entire process of fixing my car while being honest and straightforward about everything. Everything was done professionally and all the issues my car had were taken care of… If you need an honest shop with professional work that won’t rinse you of your money take your car here.”

“These guys helped me with a check engine light issue that the dealer would charge an arm and leg for but this shop was knowledgable and did the job in less than 1 hour after we had parts ordered and was amazing work. Thank you!!!”

“I've been bringing my old 08 Nissan here since 2022. I can't recommend them enough. They do great work, don't take advantage of any lack of car knowledge, won't nickel and dime you, and they are overall everything needed in a mechanic.”

“I have been bringing my cars to Rich at 3 J's for many years and have never been anything less than fully satisfied. He knows his stuff, provides honest assessments with no pressure, and he's an all around good person to work with. 5 stars all around.”

“Vehicle would reverse at idle, but would not accelerate in reverse. If vehicle was parked nose down on a slope, would not back-up due to slippage in transmission. Took it in to R&J.
Todd is a straight-shooter, honest guy, very thorough and collaborative. Transmission is fixed and
I would recommend R&J to anyone with transmission issues.”

“Highly recommend Al and the team at ETD. I thought I had a flat tire and came first thing in the morning to this location. Al took a look and suggested seeing if it could be repaired instead. A little while later my car was repaired and ready to go! I really appreciate their honesty and transparency and customer service was great! Very fair pricing and would definitely return. As a local to the area I feel I would be able to trust their recommendations moving forward. Thanks again!”

“Just walked in here to get the auto insurance inspection and the owner (Mr. Bounty) went above and beyond to help me. Will definitely recommend this place for auto repairs and inspection.”

“Great gas station
Always best prices ever
A nice shop there
Great service
Once you're a customer there you are staying with 76
Keep up your great prices”

“These guys are the best. I had my catalytic converter stolen off my car and the sales mananger for D&G told me I was lucky to stop in when I did because they were running a BOGO special. So they installed one catalytic coverter on my car and told me to keep a spare when my new one gets stolen again. I could not be any happier!”

“Ordered parts online, have no issues, parts come within 2-3 days, you will get a call if there are any issues with order, or if parts are ready for pickup. Great service, better than buying china counterfeit on ebay with fake toyota stickers.”

“I recently had the pleasure of visiting Glen Toyota for some service needs, and I must say, the experience exceeded my expectations. From the moment I walked in, I was greeted with warmth and professionalism. However, what truly made my visit remarkable was the outstanding assistance I received from Freddy.
Freddy went above and beyond to ensure that my service needs were addressed promptly and effectively. His knowledge about the intricacies of the service process was impressive, and he patiently answered all of my questions, putting my mind at ease. What stood out the most was his genuine dedication to customer satisfaction. He took the time to understand my concerns and provided personalized recommendations that suited my needs perfectly.
Moreover, Freddy's friendly demeanor and positive attitude made the entire experience enjoyable. Despite the busy environment, he remained attentive and focused on delivering top-notch service. It's evident that he takes great pride in his work and genuinely cares about the well-being of the customers.
Overall, my experience at Glen Toyota service department was nothing short of exceptional, and it was largely thanks to Freddy's outstanding service. He is a true asset to the team and exemplifies the values of professionalism and customer-centricity. I highly recommend Glen Toyota to anyone in need of automotive service, and I can assure you that with employees like Freddy, you'll be in good hands.”
