RDG Rex Diff and Gearbox for all your gearbox repairs

 Both these repair options apply to owners of vehicles of which the manufacturer’s warranty has expired. For a gearbox with minor faults (such as a noisy bearing and/or one damaged gear), it will be cheaper to strip and examine the gearbox for an accurate quote on repair cost. Although the cost is lower, this process takes longer, but still enjoys RDG’s 1-year warranty.

 For a severely damaged gearbox requiring a complete overhaul, the Reman Exchange option entails the removal of the broken gearbox and replacing it with one of RDG’s shelf stock, remanufactured gearboxes. These are priced at about the same to repair the broken unit, but can be installed within two working days, and include RDG’s warranty. Reman exchange units cost far less than a brand new gearbox.

Some of our transmission technicians have received overseas training from Original Equipment Manufacturers in the U.S., Japan and South Korea. All our technicians are amongst the most highly trained and experienced in Southern Africa.

Take your vehicle or loose gearbox to your nearest RDG branch – there are eight in South Africa – for a free assessment. Options include a minor repair using pristine used replacement parts, a Remanufactured Exchange gearbox or a 2nd hand refurbished gearbox.

A faulty passenger car transmission can be due to something as innocuous as needing a minor adjustment, software update, or replacing a battery or fuse, rectified at a minimal cost. Mechanical wear or damage to one or more bearings, gear cogs, synchro rings, clutch plates or solenoids requires a full strip down and examination. The duration of the strip and rebuild is uniform; it’s the number of new parts could cost about R12-13,000. Ideally, take your vehicle to an RDG branch for a technician to assess a fault.

Your vehicle gets a test drive (if driveable) and computerized diagnostic test to determine the nature of the fault. This could be due to a clutch problem, gear lever assembly, faulty sensor or wiring damage. These are fairly straightforward and quick to repair. If the fault is worn or damaged internal mechanical components, the transmission must be stripped down to identify these and furnish a repair quote, which takes a day or two. Parts availability from suppliers is the only factor that can affect the duration of a repair beyond a few days. RDG branches maintain a stock of Reman Exchange gearboxes for the most popular vehicle models which can be swapped out within two working days.
