Laser Tools has introduced a new three-piece set of special tools that are used when draining and refilling the automatic transmission fluid in Mercedes-Benz E-Class E350 BlueTEC fitted with the 9-speed 9G-Tronic transmission (transmission type 725.0xx).

This type of transmission can be fitted with two different sump types so the 7250 kit brings together the components needed to complete the draining and refilling job on both types. Cross references to the OE tools are 725 589 00 90 00 and 725 589 02 90 00.

Laser say that the operator will need a suitable transmission fluid pump with fluid measuring system (Laser Tools 4792 ATF dispenser recommended) plus Mercedes-Benz OEM electronic diagnostic equipment which checks fluid level and temperature. The company also recommends that technicians refer to the manufacturer’s technical service instructions and documentation for the correct procedure for the specific transmission fitted.

The new tool set is part number 7250 and is available from Laser Tools stockists.
