Gearbox Specialist — Shah Alam
Specialist CVT and automatic transmission repair with a diagnostic-first approach. Every fix starts with understanding the problem.
Promo Package
ATF Oil Replace + Auto Filter + FREE OBD2 Device — everything your transmission needs in one visit.
01
Full drain and replacement using premium automatic transmission fluid matched to your vehicle's specifications. Fresh fluid restores smooth gear shifts and reduces excess heat.
02
The gearbox filter catches metal particles and debris that build up over time. A new filter keeps fluid circulation clean and internal components protected.
03
An OBD2 diagnostic device fully compatible with the BYKI app. Plug it into your vehicle's OBD2 port, connect via Bluetooth, and you can monitor your car from your phone. Device value alone: RM150+. Yours free.
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.
Capabilities
01
Comprehensive scanner-based diagnostics, test drive assessment, fluid analysis, and leak detection. A full diagnostic report before any work begins.
Complimentary · 30 to 45 minutes
02

Scheduled maintenance including ATF/CVT fluid replacement, filter change, component inspection, ECU adaptation reset, and post-service road test.
4 to 8 hours, warranty included
04
We come to your location for a professional on-site diagnosis. If repairs are needed, we collect your vehicle, carry out the work, and return it to your door.
