If you're rebuilding a Mercedes 722.6 transmission, you probably already know about the overlap valve issues.
This Sonnax kit, part number 68942-05K, is the fix.

It's brand new, still sealed up, and made right here in the United States.
The kit comes with aluminum sleeves and high-temp rubber o-rings - exactly what you need to repair that bore wear.

Just a heads up, this is just the sleeve kit.

The valve body, valves, and springs are not included, so don't expect a full rebuild in one box.
It also crosses over with 78741DK and S78741DK if you're looking at interchange numbers.

Sonnax makes good stuff, so you know this is quality.
