722.9 Transmission Service Kit with 9L ATF and Filter

If your 2014-2021 Mercedes Sprinter 2500 or 3500 with the seven-speed automatic is shifting hard from first to second when cold, shuddering at light throttle in the 40 to 50 mph range, or hunting between gears on a hill, the first thing to rule out is tired fluid and a loaded filter. This kit packages a 722.9 transmission filter, a new pan gasket and nine one-liter bottles of transmission fluid, so one box covers a pan-drop service on a working van with fluid to spare for topping off at the hot check. Components are FEBI and LAIPZ, listed under kit number Sprinter7SPD9L-KIT.

What the filter and pan service does in a 722.9

The 722.9 (Mercedes calls it 7G-Tronic, internally NAG2) builds its seven forward speeds with clutch-to-clutch shifts controlled by an electro-hydraulic valve body and control unit that bolt to the bottom of the case, down in the fluid. The filter sits on top of that assembly inside the pan and catches the friction material and fine metal the clutches shed before it is pulled back through the pump and into the valve body bores. A Sprinter that tows, idles at job sites or runs stop-and-start delivery routes runs its fluid hotter and longer than a passenger car does, and a partly blocked filter tends to starve one circuit first, which shows up as one bad shift rather than a total loss of drive.

Symptoms that point to an overdue service

• Hard or delayed 1-2 upshift when the van is cold, smoothing out once warm
• Delayed engagement when shifting from Park into Drive or Reverse
• Converter shudder at light throttle on the highway
• Gear hunting on grades or with a trailer behind it
• A limp-home event that clears after a key cycle
• Fluid that smells burnt or comes out dark instead of clean

How to confirm before you buy

Scan the transmission control unit first. A stored solenoid, speed sensor or ratio fault means a hardware problem that fresh fluid will not fix, although a service is still the right starting point before any valve body work. Then pull the drain plug and look at what comes out and at the pan magnet once it is down: fine gray paste is normal, chunks or flakes are not. Our 722.9 filter and pan service guide covers how to read the fluid and the pan, and the high-mileage service checklist lists what else to inspect while the pan is off, since the 722.9 shares much of its design lineage with the 722.6.

Fitment

This kit is listed for the Mercedes 722.9 seven-speed in 2014-2021 Sprinter 2500 and 3500 vans. Sprinters were built with more than one automatic over that span, so check the transmission identification tag before you order: if it is not a 722.9 seven-speed, this is not the right kit. Mercedes also split the 722.9 into two fluid and pan generations, and a replacement transmission may not match what the van left the factory with. Check the specification printed on the fluid bottles against the spec your unit calls for, and do not mix fluid specifications. If you are unsure, send us the year and VIN before ordering. Every 722.9 part we carry is on the 722.6 and 722.9 parts page.

Install notes

• Work with the van level on the ground or on a lift that holds it level, never on one side of jack stands.
• Drain, drop the pan, remove the filter, and clean the pan, the magnet and both sealing faces completely. No sealant on the new gasket.
• The pan bolts thread into a magnesium case and are aluminum stretch bolts that factory procedure says to replace, not reuse. The Mercedes procedure is 4 Nm then a further 180 degrees.
• The 722.9 has no dipstick. Fill through the drain port with an adapter, then set the level with the engine running and the fluid at the temperature Mercedes specifies, letting the excess run out of the overflow pipe. The drain-port adapter in our 722.9 filter kit with fill adapter makes this a clean job.
• A pan-drop service changes only part of the fluid because the converter holds a large share. Plan on a second service a few hundred miles later on a badly neglected van.
• Reset the transmission adaptations with a capable scan tool afterward so shift fill times relearn on the new fluid.

For a passenger car that only needs six liters, the 6-liter 722.9 service kit is the better fit.

Is nine liters enough for a Sprinter 722.9 service?

For a pan drop and filter change, yes. Draining the pan does not remove the fluid held in the torque converter, so nine liters covers the refill plus extra for the hot level check. A full exchange that also drains the converter takes more.

Does this kit fit every 2014-2021 Sprinter?

It is listed for 2500 and 3500 vans with the 722.9 seven-speed. Confirm the transmission ID tag shows a 722.9 before ordering, and match the fluid specification on the bottles to the one your unit calls for. Send us the year and VIN if you want us to check.

Can I reuse the pan bolts?

The 722.9 pan bolts are aluminum stretch bolts going into a magnesium case, and Mercedes procedure calls for new ones every time the pan comes off. Reused bolts can stretch and snap.

How do I check the fluid level without a dipstick?

Fill through the drain port, start the engine, bring the fluid to the temperature Mercedes specifies and let the excess drain from the overflow pipe until it drips, then install the drain plug with a new seal. Checking cold will leave it overfilled.

Will a service fix a harsh shift on my Sprinter?

It fixes shift complaints caused by worn fluid and a restricted filter, and the adaptation reset afterward often smooths shifts further. It will not fix a failed solenoid, speed sensor or conductor plate, so scan for stored codes first.

What else should I replace while the pan is off?

Replace the pan gasket and bolts every time and the overflow pipe if it is damaged, using one of the same color. If the pan shows heavy metal, stop and diagnose before refilling.
