Gearbox Repairs

Gearbox repairs needn’t be costly. Generally a main dealer would try and convince you to completely replace your transmission with a new unit, which results in a quote ranging typically between £5,000-£10,000. Talk to the team at Essex Automatics as we can advise you on carrying out repairs or rebuilding your existing unit saving you from a costly main agent repair.
The typical signs you may have a faulty transmission are:







Should you experience any of the above do not hesitate to have the issue looked at by a qualified transmission specialist. Catching the problem early could literally save you a fortune.

At Essex Automatics we carry out Gearbox Oil Servicing. Replacing your gearbox oil at the correct intervals is crucial to prolonging the life of your transmission and can often help cure very early signs of transmissions faults. We carry out our servicing using only Genuine Manufacturer Oil and Genuine parts ranging from gaskets and seals to filters and sump pans.
