Specialiazing in Repair, Maintenance, Overhaul of Allison Transmission : Allison AT 545

 

Maju Engineering Services Sdn. Bhd (MESSB) offers not only new Allison Transmissions but we also have a vast stock of rebuilt Allison Transmissions. The gearboxes are overhauled by factory trained mechanics who with the use of new and genuine Allison parts create an automatic transmission which is as good as new.

Every rebuilt transmission is fitted with new bearings and where applicable the latest modifications are implemented. Finally every rebuilt transmission is severely tested under load. All this results in a high quality rebuilt transmission which equals a brand new transmission. Drive Line Systems has a vast stock of rebuilt AT/MT/HT/CLT transmissions but we are also able to offer rebuilt Off-Highway transmissions like the CL(B)T5000 and 6000 Series.

Today's engine and axle options have made specifying a truck more demanding. We can help. Whether you're looking for enhanced fuel economy, increased productivity or high performance, we have the tools to help you select an Allison Transmission that will match your specific application needs.

So if you are searching for a rebuilt Allison AT 545 transmission so you can proceed with your business as soon as possible, don’t hesitate to contact us and ask for a quotation which meets your requirements.
