Gearbox Diagnostics

Gearbox Diagnostics & Fault Finding

When your vehicle experiences a gearbox problem, it is vital to take it to a reputable specialist. While connecting a car to a diagnostic machine is the logical starting point, a fault code for “Component A” doesn’t always mean that part is the root cause—sometimes, the real issue lies with “Component B.”

Advanced Technology & Expert Knowledge
Different diagnostic tools offer various functions to assist technicians. We use the same online high-level dealer equipment found at Audi, VW, Seat, Skoda, Ford, BMW, and Mercedes.

By combining this top-tier equipment with our expert technicians—who are specifically trained to identify and interpret complex codes—we can provide an accurate diagnosis that standard garages might miss.

What Our Diagnostic Check Includes:
We always recommend bringing your car to us for a full inspection. Our check includes:

System Scan: Connecting the vehicle to our advanced diagnostic software.
Fluid Check: Inspecting the transmission oil level and condition.
Road Test: Where possible, we carry out a short road test to experience the fault firsthand.

From there, we will be able to advise you on the best way forward to get your car back on the road.

My wife’s ford Bmax went to different garages with a gearbox problem before ending up at Ford and £600 later & going round in circles, I found Brittanic on google, I went down to their workshop in Tottenham and had a discussion with Nick. He quickly arranged for my car to be collected. That day I was told what was wrong with costs. Two days later I have collected it and drives great. Thanks to the team at Brittanic for being very clear & honest, I am happy with the experience.

This company in my opinion are first class, went over and beyond. Dropped my car in on Tuesday, gearbox was done by Friday, super quick turn around. Thanks guys, wife is over the moon, car drives better than new now.

I have a Skoda Octavia hybrid. I was experiencing issues with my DSG gearbox. After going to 3 other garages I was recommended to go to Brittanic Auto Transmission. Nick arranged for collection of my car. Absolutely brilliant service to be honest here, no other garage could have fixed my car. So thank you to Nick and his team.

I drive a 2016 Audi A3 (7-Speed DSG, DQ200 Mechatronic) and had been dealing with frustrating juddering and clanking when shifting from 1st to 2nd gear. Enter Nick from Brittanic Auto Transmission – absolute legend! From the moment I called, Nick was on it. Within just one day, he diagnosed the issue, replaced the clutch, and had me back on the road. No delays, no drama – just professional, efficient service. If you’re having DSG issues, don’t wait – give Nick a call. Highly recommended for top-tier expertise and fast turnaround.

This company repaired my Seat Leon Cupra gearbox via my warranty company and can honestly say these are the best company I’ve dealt with. Nick and Paul were brilliant. Thank you both.
