We offer the rebuild of the gear actuator from the SMG I gearbox. This gearbox was installed in the BMW E36 M3 only. This part is responsible to select and engage the gears of the gearbox. In case of a leaking gear actuator, the SMG refuses to engage one or more gears. As part of the repair, the actuator will be fitted with seals manufactured by a specialized company from Germany. They are perfectly meeting the requirements of the hydraulic fluid and are suitable for the extreme conditions in the SMG system.
We offer two ways for the repair:

Way A: Direct overhaul of your actuator
In this case you send us your actuator (to Germany) and we’ll refurbish it directly. Normally we finish the work and ship the part back within 24 hours.

Way B: Provision of a ready overhauled actuator
This service is only available under certain conditions. If on stock, we’ll ship a pre-overhauled and ready-to-use actuator towards a deposit payment (core charge) of 300€. You can change the part in one single repair process and the downtime of the car stays minimal. After the change you have to return the old part to us within one month (counting from the day when our part arrives at your place until the day when you ship it back / hand it over to the courier). If you return the part later than one month, but within 6 months, we will refund 70% of the deposit amount (30% deduction). After 6 months we can no longer refund the deposit amount for legal reasons. The return shipment is your responsibility, the costs are to be covered by you. In general the part must be in a repairable condition, which means no damages besides the normal attrition during operating. Please mind: the deposit amount does not include the price of the repair – the amount is to be paid additionally.
