4MATIC / 7G-Tronic automatic transmission repair kit
VAICO has developed a clever repair solution for the 7-speed automatic transmission in all-wheel drive Mercedes models (4MATIC).
Available languages:
The Mercedes 7-speed transmission 7G-Tronic is a highly developed automatic transmission that can quickly become an economic nightmare for the car owner if the shaft to the front axle differential is defective. When this problem occurs, Mercedes-Benz does not offer a replacement part for repair. Instead, replacement of the entire gearbox is recommended, which causes repair costs to skyrocket. Long downtimes and high costs are the inevitable result. But VAICO has developed a solution that avoids the expensive replacement of the entire transmission and offers a cost-effective, fast and efficient repair.
With the VAICO repair kit for the 7G-Tronic transmission, you can fix the problem in a targeted manner – at a fraction of the cost of a complete transmission replacement. Fortunately, the economic nightmare for your customers will come to an end and you can impress them with a clever, practical repair solution.
Causes of 7G-Tronic transmission damage: How a minor defect has major consequences
A defect in the 7G-Tronic transmission can have various causes that gradually impair the entire functionality of the transmission. The joint between the drive shaft and the front axle differential and the rubber sleeve mounted in front of it are particularly susceptible to damage, which can result in serious consequential damage.
The rubber of the boot becomes porous over time and can tear – a natural wear process that is not immediately noticeable. But this is exactly where the problem begins: splash water, and in winter road salt, penetrates the drive shaft joint through the damaged boot. The result: corrosion sets in and the joint begins to loosen. Over time, more and more play develops in the joint, which leads to the cardan shaft hitting the gearbox – which not only causes extremely unpleasant noises, but can also lead to the cardan shaft breaking if it is not repaired.
But that’s not all: the bearings on the internal gears and shafts can also wear out over time. If the bearings come loose, the fragments are distributed throughout the gearbox and cause further damage. Gear wheels can be damaged by the bearing parts, resulting in irreparable damage to the gearbox. In both cases, the entire transmission needs to be replaced, which drives up the costs massively – not to mention the long downtime for the vehicle owner.

All-wheel drive without all-wheel drive?
In our new video, we take a close look at a Mercedes S-Class S450 4MATIC. Actually, ‘4MATIC’ stands for all-wheel drive – but whether it still works on this car is questionable! We’ll show you which repair botches were made here, why the all-wheel drive no longer works and how our repair solution for the 7G Tronic could have prevented this. You’ll also find out what clever tips there are for avoiding similar mistakes.

The VAICO-EXPERT KIT+ provides you with the best repair solution for the 7G-Tronic transmission. Not only can you avoid time-consuming breakdowns, but you can also offer your customers an economically attractive alternative that more than pays for itself.
No oil in the repair kit? That’s what’s behind it!
Oil leaks when the gearbox is opened – it needs to be changed or, even better, flushed. Our repair kit is suitable for the 7G-Tronic Plus and 7G-Tronic transmissions. However, as these transmissions require different oil, we have deliberately not included the oil in the kit. Corresponding oil change kits are available separately from us.
