Quantum Mechanics Ltd. specializes in transmission and overdrive products and services for classic British cars, including MGBs and TR6s, as well as other European and Japanese makes. The business is very professional and extremely professional, known for superb and awesome work. It is very busy but always gets back to clients, with email correspondence being best. The technician is easy to talk to, honest, and a very experienced technician. The work is consistently completed on-time and for the quoted price, with the final bill often less than the estimate. The business meets all commitments and clearly lays out what is to be done with detailed written estimates. Turnaround times are reliable, with examples of a promised four-week turnaround being completed in two and a half weeks. The units operate flawlessly after installation. A common practice is the refurbishment and overhaul of gearboxes and overdrive units, such as J-Type overdrives. The business offers products not available elsewhere. A helpful approach is suggesting clients provide a parts gearbox, which saves time and money and can result in a generous credit for unused parts. The process includes disassembly, diagnosis, and leak testing. Quantum Mechanics Ltd. is highly recommended and comes without reservation, with clients stating they cannot thank them enough and know others will be happy with the service.

The 1970 MGB overdrive transmission that John Esposito's shop overhauled for me works awesome. No surprises, extremely professional and clearly laid out what was to be done. I can't thank them enough. Mark
