Transmission repair

The transmission is one of a vehicle’s most complex and critical components, transferring engine power to the wheels. When a transmission starts playing up, gears will not engage or unusual noises come from the system, delay can leave the car completely immobile and lead to very high costs. The Carstop chain of workshops includes specialists with long experience in the field, who carry out in-depth diagnostics and complex repairs on both manual and automatic transmissions (including DSG and CVT). Trust your car’s transmission to professionals who resolve every drivetrain problem quickly, efficiently and to manufacturer standards.

Carstop workshops include the following among their maintenance services

In-depth mechanical and electronic transmission diagnostics and fault code reading
Repair of automatic and manual transmission assemblies, valve bodies and clutches
Complete transmission removal, component replacement or fitting of a new unit

How to recognise when you should bring your car in for a check

Gears will not engage, they "slip", or the transmission goes into limp mode
If a manual transmission is hard to put into gear, or an automatic starts revving up under acceleration without moving (slipping), there is serious wear. In the event of a major sensor or hydraulic fault, the car's computer switches the transmission into limp mode to protect it, limiting the gears available
Loud whining, droning or knocking while driving or when changing gear
Unusual mechanical noises around the transmission usually point to wear in the internal bearings, gears or differential. When symptoms like these appear the car must be brought in for a check immediately, as breaking metal particles can irreversibly destroy the entire transmission casing from the inside.

Does a faulty transmission always have to be replaced with a completely new one?
Generally not. In most cases transmission faults can be partly repaired. Carstop specialists open the unit, identify the specific worn components (such as bearings, seals, clutch plates or electronic modules) and replace them with new ones — a considerably cheaper solution for the customer than buying a new transmission.
What are the main reasons car transmissions fail?
The most common cause is servicing that has not been done on time and the resulting low or contaminated oil level, which causes components to overheat and creates excessive friction. Transmission life is also affected by an aggressive driving style, constant driving in demanding conditions (such as overloading vans) and natural mechanical wear over time.
