722.6 Transmission Pan Upgrade (Stock or Deep) – Cooling + Drain + Leak-Free Seal

For 722.6 owners chasing temps, leaks, messy services, or warped OEM pans

If you’re searching because your 722.6 transmission is running hot, you’ve got a pan seep/leak, your last service was a mess with no drain, or the OEM stamped steel pan feels flimsy/warped… this is the upgrade that fixes those pain points. More capacity, real cooling fins, a proper drain, and a machined sealing surface.

Why People Replace the OEM 722.6 Pan

  • Overheating / high ATF temps: extra capacity + fins help drop temps (often 10–30°F).
  • Slow seep/leaks: machined flat flange improves gasket contact and sealing.
  • No drain plug: side drain + magnetic plug makes fluid changes clean and easy.
  • Warped steel pan: thick cast aluminum resists bending and improves durability.
  • Hard-use AMG driving: more fluid + cooling = better longevity under load.
Cooling + Capacity
Finned cast aluminum with extra volume helps reduce ATF temps and stabilize performance—especially on 55 AMG / 55K cars.
Clean Service (Drain + Magnet)
Side-mounted drain makes changes safer and less messy. Includes a magnetic drain plug to capture debris.
Leak-Resistant Seal
Machined flat gasket surface and thick flange reduce warping and help prevent the common “slow seep” you see with OEM pans.

Fitment (722.6 / 5-Speed Automatic)

Fits Mercedes-Benz 722.6 automatic transmissions (aka 5G-Tronic / NAG1) used across many AMG and non-AMG platforms. Common searches include: 722.6 pan leak, 722.6 overheating, NAG1 deep pan, 5G-Tronic drain plug, and 55 AMG transmission pan.

Fitment note: Confirm you have a 722.6 transmission before ordering. If you’re unsure, send your year/model/trim (or VIN) and we’ll help verify.

Installation Notes

  • Do not use the factory gasket with this pan.
  • Use RTV Black for proper sealing.
