“My Perodua Myvi CVT was slipping badly. One X diagnosed the problem in under an hour — free of charge — and gave me a clear written report before touching anything. The repair has been solid for over a year.”

Gearbox Specialist — Shah Alam
Specialist CVT and automatic transmission repair with a diagnostic-first approach. Every fix starts with understanding the problem.
Our Approach
Most workshops replace parts and hope for the best. We start differently — with a thorough, methodical diagnosis that identifies the actual root cause before any wrench is turned.
This diagnostic-first discipline means your transmission problem gets solved, not patched. It means fewer return visits, fewer unnecessary part swaps, and a repair built on certainty.
Free professional diagnostic assessment on every vehicle.

“Brought my Honda City in after two other workshops gave me different stories. These guys pinpointed the issue immediately. Professional, honest, and the 12-month warranty gives real peace of mind.”

“Toyota Vios gearbox was jerking at low speed. Full overhaul done within the week. The car drives smoother than it did when I first bought it. Highly recommend One X Transmission.”
