Heavy commercial transmissions specialists


Founded in 1955 H L Smith Transmissions Ltd is the U.K’s leading independent specialist in the remanufacture of heavy commercial transmissions supplying a complete service including manual and automatic gearbox, driveheads and axles, along with powersteering and propshafts. H L S Ltd has become the one stop shop for all makes of drivetrain product whatever the origin.


Based in the heart of the West Midlands operating from 90,000 sq feet of purpose built workshops and storage areas our Company is in the right position to serve the needs of the ever growing transport and logistics market.


Dedicated teams of trained engineers bring together their experience and engineering expertise providing flexibility to meet the requirements of every customer whether a multi national or an owner driver. This response and the quality of service that is offered had brought the Company to the position it now holds within the industry.


With the ever-growing complexity of the manual gearbox in todays vehicles, training and product knowledge is paramount. Continual investment in the latest test and diagnostic equipment allows our engineers to work with and diagnose the new generation of E.C.U controlled manual transmissions including AS Tronic and I- Shift.


With the ever-growing use of automatic transmissions in various applications our automatic remanufacturing plant deals with Allison, ZF, Clark and Twin Disc covering PSV, municipal and off highway requirements. An on site fitting and diagnosis service is available along with a technical helpline to pin point what services will be needed and provide the engineer with the information required to solve the problem.


Services to the propshaft and drivetrain product range encompass exchange units, parts and repairs. An expanding part of the business is modifications to existing drivelines for the chassis alteration industry and the supply of new shafts to OE specification.


Driveheads, axles and steering are not only provided to UK Fleet Operators but also our company supports the UK MOD on its logistical vehicles along with many other defence organisations worldwide dealing with Leyland, Foden and Bedford along with many special purpose vehicles.


Every unit be it automatic, manual or steering undergoes a rigorous test cycle to ensure the OE protocol is achieved before it goes through to final paint and onto despatch. This test procedure is critical to ensure that the end user moves forward with a trouble free product at time of fitment.


All products are sold on a service exchange basis and with over 2000 finish items on stock most orders can be satisfied on a same day or next day delivery, reducing vehicle downtime and inconvenience to the operator. Delivery is provided by our own fleet of 10 vehicles or by way of one of the major national courier companies, depending on location and timing.


H L Smith offers a unique facility bringing together service and quality over a wide range of drivetrain products. Supported by a dedicated sales and technical team we are here to answer your questions and to provide the product you need whatever the demands.
