722.9 Transmission Service Kit with 9L ATF and Filter

Everything needed for a full fluid and filter service on the Mercedes 722.9 seven-speed automatic as fitted to the 2014-2021 Sprinter 2500 and 3500. The kit pairs FEBI and LAIPZ components with nine liters of transmission fluid, which is enough for a drain, filter change and refill with fluid left over to set the level hot. Shipping weight is 20.8 lb.

The 722.9 runs an internal filter behind the pan and a conductor plate that sits down in the fluid, so this service is not optional maintenance on a van that works for a living. Sprinters that tow or run stop-and-start delivery routes cook the fluid well before the mileage on any lifetime-fill claim, and dirty fluid is the first thing that shows up as a shift complaint on these units.

Symptoms that mean the service is overdue: a delayed or hard 1-2 engagement when cold, a shudder at light throttle around 40 to 50 mph as the converter clutch tries to hold, hunting between two gears on a grade, or a limp-in event that clears on a restart. Fluid that comes out brown instead of red confirms it before any scan tool does.

Do the job with the van level, and set the final level with the fluid at operating temperature - the 722.9 has no dipstick and the correct level is temperature-dependent, so a cold fill reads high and a hot overfill will aerate. Replace the pan gasket rather than reusing it, and reset the transmission adaptations after the refill so the unit relearns clutch fill times on clean fluid.
