Mercedes 722.3 Transmission 2-3 Upshift Flare Repair K1+K2 Spring Kit for M119

Description

Item Description:
This is a fix for transmission slip/flare on 2-3 upshift at partial load; for Mercedes 722.3 series automatic transmissions with M119 V8 engines, from 1992 through 1995. If your automatic transmission shifts fine with the exception of a flare on the shift up from 2nd to 3rd, and you've exhausted all other adjustment options, then the K1 Spring Kit might be the solution.
This kit ALSO includes the green K1 accumulator piston, with new Teflon seals.
The green accumulator will fit all 722.3 transmissions used with M119 engines, part number
126-277-09-32
.
In addition, a new, stock replacement blue K2 accumulator piston with new Teflon seals
is included, with new stock spring train. The blue K2 accumulator is part number
126-277-84-32
, and may fit other transmissions/engine combinations, however you will need to remove your existing K2 accumulator and verify the part number matches. The K2 affects the 3-4 upshift. The K2 parts are not intended as an upgrade, but rather replacing old/worn parts with new fresh ones.
This kit is a drop in replacement for the existing K1 and K2 spring + piston assemblies in your transmission's valve body. Although you do not need to remove the valve body from the transmission, you must drain the fluid out of the pan, and remove the pan to access the valve body. The most convenient time to install this K1+K2 kit would be during a transmission fluid & filter change, which Mercedes recommends every 30kmi under normal service (15kmi with severe service).
Although the TSB shown in the photos indicates the K1 kit is intended for use with the M104, M119, and M120 engines; I am not sure of all the applications for the K2 piston, which is why I am listing this K1+K2 setup as only for M119 V8 engines. It may fit other 722.3 transmissions, but please check part numbers before ordering.
These are Genuine Mercedes-Benz parts, made in Germany. The K1 spring kit will come pre-assembled as seen in the second photo.
PLEASE NOTE:
This kit DOES NOT fit the 722.0, 722.1, 722.2, 722.6, or 722.9 transmissions! It may not fit 722.4 or 722.5 either. If you are uncertain about fitment, please contact me BEFORE buying. I lose $$$ when you return a kit that won't fit your transmission. Contact me with your year, model, and/or VIN and I will be happy to discuss fitment before you purchase. Thank you!
