About Us


A detailed point by point diagnostics is necessary to detect irregularities and out of sync components within the transmission unit.

Full / Partial Rebuild

A transmission rebuild may be necessary when the issues are major and a simple replacement/realignment will not suffice to ensure continuous problem-free mobility.


Much like the discipline of changing your engine oil within 10,000km or 6 months of usage, the transmission unit has a consumable that is often overlooked, the ATF.


The much dreaded engine fault indicator may be attributed to a transmission issue.

Some of our customer says…

5 star! Great service, cheap prices, excellent workmanship! The team here, got my aged Škoda working like brand new, again... Thank you Ah Hui and the rest of the crew!

Replaced Honda Airwave CVT gearbox with fast turnaround time and reasonable price. Very humble, honest and knowledgeable boss. Solved my shudder issue about 90% that is due to throttle and iac valve too

Thru teleconversation, he (Ah Hui) sounded so down to earth and simple, makes you might think that his is just another street-side workshop until you visit him. Handed him my B200 for bearing replacement. After two days it turn out to be good and affordable. A workshop you can trust..
