In the recent years we have continuously invested in the equipment of our modern workshop and machinery.
With the help of the most modern machines which complement each other perfectly we are able to fulfill your quality requirements in the best possible way.
Due to our know-how, our technically high-quality equipment and the possibility to acquire spare parts internationally we are leading in the repair of automatic transmissions and we want to meet this high standard in the future as well.
With us you receive high quality which results out of decades of experience.

It depends very much on what kind of problems the automatic transmission causes. In general: As soon as problems are noticeable you should act immediately.
A replacement transmission is not always required straightaway as some transmission problems can also be solved in an uncomplicated way.
If you notice for example that despite high engine power it is no longer possible to drive at high speeds and the engine rotational speed is very high it may simply be due to the wrong level of transmission oil.
If individual gears can no longer be used or the reverse gear no longer works the couplings in the transmission are often defective.
A defective torque converter is noticeable by the fact that the vehicle has neither forward nor reverse power.
Defective switching or pressure control valves, speed, pressure or temperature sensors, as well as defective valve bodies or a lack of oil can be a possible cause of errors.
Important: Damage elimination is by no means automatically also the elimination of the cause, i.e. if the cause of the damage is not also eliminated the same damage can occur again within a short time.
With newer electronically controlled transmissions an external error ( e.g. a defective throttle body sensor, control computer, air flow meter or wiring harness) can also be the actual cause of transmission damage.
In the same way, there may also be control and actuation problems which should ideally can be read out with appropriate diagnostic devices.
If the transmission oil is not black, does not smell burnt and there are no splinters in the transmission oil, there is a realistic chance that the transmission is not damaged or not badly damaged. In such a case a cheap repair might be possible.
In case of insignificant problems like shifting quality, vibrations, etc. with a maximum mileage of approx. 150.000-250.000km the problem can often be solved. If and in which way this is possible depends on the type of transmission, age and load of the vehicle as well as the drivers driving style.

If the extent of damages can be precisely defined through diagnosis, a targeted repair can sometimes be carried out. It may also not be necessary to remove the transmission for this purpose.
In case of massive damage affecting the entire transmission or in case of certain types of damage, a general overhaul cannot be avoided. For example, if chips are already present in the entire transmission.
During a complete overhaul, the automatic transmission is entirely deconstructed and thoroughly cleaned. During a complete overhaul, the automatic transmission is entirely deconstructed and thoroughly cleaned. The highest level of cleanliness is necessary when a transmission is overhauled. All wearing parts are replaced, regardless of whether these parts are still functional or not.
What is exchanged by default?
The range also depends on the transmission technology. Here we distinguish between the classic automatic transmission, the continuously variable transmission (CVT) and the dual clutch transmission (DCT).
If the extent of the damage can be precisely defined in the diagnosis, a targeted repair can sometimes be made. In case of minor gear damage or if the damage can be clearly limited, we also carry out specific repairs. Repairs are done at actual workload on the basis of a cost estimation.
Repair only makes sense at all for transmissions that do not show a high degree of contamination. In such cases wearing parts can be reused for price reasons.

**only possible if the degree of oil contamination is not too high
There is no generally applicable standard for the repair of an automatic transmission and therefore completely different services are provided, which are very difficult to compare.
There are some questions you can ask to compare the different services.
You should act immediately as soon as you notice problems with the automatic transmission. At first signs, it is often possible to repair minor damages to the transmission before serious defects occur.
For technically skilled vehicle owners it is recommended to check the transmission oil first. To do this, pull out the transmission oil dipstick and check the transmission oil. The oil level is checked via the overflow pipe - at max. 35° - 40° C - please take note of the manufacturer's instructions. Furthermore, it would make sense to remove the oil pan and check both the oil pan and the filter screen for contamination.
If the transmission oil is not burned yet, i.e. red (or yellow in some transmissions) and there are no splinters in the transmission oil, there is a realistic chance that the transmission is not or not significantly damaged.
In this case, it would make sense to make an appointment with us to check whether it might be a control or actuation problem.
In mechanical-hydraulic transmissions this can be caused by a defective vacuum actuator, a defective kickdown cable, a suspended centrifugal governor, a defective valve body case or a lack of transmission oil.
With newer, electronically controlled transmissions an external fault (e.g. a faulty throttle position sensor, control computer, air mass meter or wiring harness) can also be responsible.
Faulty shift or pressure control valves, the speed - pressure - or temperature sensor, as well as valve body cases or a lack of oil can be possible causes of errors. If your vehicle has neither forward nor reverse power it is quite common to assume that the torque converter is defective.
If the transmission oil turned dark brown or black or if the transmission oil smells burnt, then the automatic transmission must be removed in any case.
IIf this is not the case, then you should remove the oil pan and check it for metallic abrasion. If there is strong metallic abrasion or even larger splinters in the oil pan and on the magnet, the mechanical defect is too strong to be repaired in the installed condition. In case of heavy dirt and/or splintering, a general overhaul is absolutely necessary to remove all dirt particles from the transmission.
