A transmission/gearbox in basic terms is the system which carries the power produced by the engine to the drive axle through the use of various gears. The modern automatic vehicle transmission systems are very complex units which are made of many electronic, mechanical and hydraulic parts. For this reason, they fail well before the engines. When properly maintained, a modern engine will very easily last for more than 200,000 miles without requiring to be replaced unlike transmission systems which normally fail after between 80,000 miles to 150,000 miles. This range is varible in that the longevity of transmission systems lifetime varies and also depending on usage and maintenance factors.

Each time a transmission system changes gear, bands and clutches inside of the transmission platform will apply and get released to allow for the gear shift to take place. For each shift the transmission system wears out and the higher the speed at which you are accelerating at the time of the shift, the greater the amount of wear that the transmission will go through. Generally vehicles doing long haul runs will have less use of the gearbox, whereas city driving requires many gear changes and the gearbox can wear down considerably faster.

Gibbs Truck Transmissions performs gearbox repairs, installations, replacements and maintenance as well as offering brand new gearboxes for a range of models. In case of emergencies we offer a 24/7 round the clock emergency assistance should it be required.
