I have been unable to document exactly which 722 transmissions this fits.

This may help sort out what you need, Use Page Translation = it is in Russian.

K1 - spring kit 1262704477
K1 - piston 1262700335
K2 - part number on the tube is 1262778432, however the kit part number is 126 270 04 35
K2 - piston 1262700435
K2 - piston 1262700535
B1 - piston 1262700235
B1 - piston 1242700035


It is rare to need new brake bands, and adding them to the order can easily double the total cost.

Brake band B1
MB# 1262701862

Brake band B2
MB# 1262702062

Hmm. I thought the 722.3 was new for the W126 chasis. When did it make its first appearance?

1991 350SDL. 230,000 miles (new motor @ 150,000).

2013 Fiat 500E. 20,000 miles, 80 miles at a time.
2012 Passat TDI. 95,000 miles. More space, power, and fuel economy than the Benz
2004 Touareg V10 TDI. 150,000 miles. One of 450.
1999 Jetta TDI. 310,000 miles.
1992 Jetta ECOdiesel. 156,000 miles. 1 of 48. Sold.
1991 Jetta ECOdiesel. 430,000 miles. 1 of 700. Sold to VeeDubTDI, totaled in front of our house
