Posted on Google TJ TipeneTrustindex verifies that the original source of the review is Google. For the longest time, my 2019 Holden Colorado would shudder between 80-100km/ph.. Gearbox factory resolved that issue with a torque converter replacement and an all oil service ☺️ It took 3 days to complete & well worth the wait! They also provide a courtesy cars, which was a bonus for me. Reasonable price & customer service is outstanding. I would highly recommend for any gearbox work 💯 Thanks again Gearbox factory team, I drove off, a very happy gal ☺️Posted on Google B MTrustindex verifies that the original source of the review is Google. Spoke to Steve on the phone re: an issue with my Subaru Legacy & asked me to bring it in to be checked. No wait time. Very professional on the phone & very accommodating. Chris (one of the mechanic) took my car for a test drive & told me what the issue was in less than 30 seconds! This was an issue my mechanic & I have been mulling over for a period of time now thinking it was far more serious. I am more than impressed with Chris’ ability to diagnose the problem at a very short time frame. Thanks Chris!!!Posted on Google Info OnlineTrustindex verifies that the original source of the review is Google. Good honet people to deal with. Very professional. Been around for a long time.Posted on Google Blue TannerTrustindex verifies that the original source of the review is Google. Had our car transmission serviced here, I was more than happy with the service from the team.Posted on Google Robson SmithTrustindex verifies that the original source of the review is Google. TLDR: Huge thank you to The Gearbox Factory team — exceptional service, honest advice, and great value for both me and my VW. After a few nearby mechanics told me my 2009 Golf needed a full transmission replacement, I decided to look further afield and came across The Gearbox Factory. From the first chat, Steph and Paul were understanding, polite, professional, and transparent. They explained everything clearly and made the whole situation far less stressful. An additional shout‑out to Paul for keeping me updated throughout the process and letting me know the best time to come collect my car. Since I live about an hour away, those updates made planning everything so much easier. My VW’s transmission is now running much smoother than before, and the total cost was absolutely worth it. If you’re looking for a trustworthy transmission, gearbox, and driveline specialist, this place is the one for you.Posted on Google Dan PowerTrustindex verifies that the original source of the review is Google. Great service. Friendly staff. Clear communication on work to be carried out, and outlined best options while looking after my costs. Highly recommend!Posted on Google Marilyn PlewsTrustindex verifies that the original source of the review is Google. What a great team. Called in with my 1992 classic car, which had a problem with the Automatic Transmission. Just wanted to see if they were familiar with the car and if so, could they diagnose the issue. Stephen took the car out for a drive, diagnosed the problem and then got his tools out and fixed it. If I could give more than 5 stars, I would!!!
