Gearboxes

Is your vehicle struggling to shift gears, making grinding noises, or leaking transmission fluid? These can be early warning signs of gearbox trouble. At Scarlett Auto Services, we offer expert diagnostics and repairs for both manual and automatic gearboxes to keep your car running smoothly. Common signs of gearbox wear include:

Tips to Prolong Gearbox Life:

  • Check and change transmission fluid regularly: Dirty or low transmission fluid can cause serious wear and overheating. Keep it clean and topped up.
  • Avoid aggressive driving: Rapid acceleration and hard gear changes put unnecessary strain on your gearbox.
  • Use the correct gear for the speed: Don’t lug the engine in a high gear or over-rev in a low one—both can cause long-term damage.
  • Keep up with scheduled services: Regular servicing can spot early signs of gearbox trouble before they become costly repairs.


At Scarlett Auto Services, we specialize in gearbox maintenance and replacement for all vehicle makes and models. Our experienced technicians are equipped with the latest diagnostic tools to ensure your gearbox operates optimally.

I have a 2004 SLK 350 R171 which I intended to take to France to rally in September. Scarlett Auto Service’s listened carefully to my concerns, and with attention to detail ensured that not only was it fit to take to Bordeaux, but that I won the overall rally beating an Aston Martin, Porsche, Jaguar & Ferrari over 2 days. Had no issues at all for the entire trip. Not bad for an 18 year old car. What I really like about this friendly & accomplished garage is that  they fully engage, include you in the process, and nothing is seemingly too much trouble. I had, for example, a problem with the wing mirror motor assembly and Scarlett’s went to some trouble to source an affordable original second hand replacement. Something that previous garages had not attempted. The work I requested was done to a very high standard; with a wide range of expertise being shown; they invited me to inspect their work: & importantly I am always made to feel welcome. As a fussy Mercedes owner I trust them implicitly & would not take my car anywhere else.

I use Scarletts Auto Services to look after my Ford Escort RS Cosworth. Stuart and his team have always been very professional, reliable and trustworthy and I feel totally at ease leaving my car with them. I would highly recommend Scarletts.
