I thought I would post some pics from my work and since there are alot of threads about the 722.9 tranny I thought I would post some pics of some I have disassembled to replace the b1 and b3 clips. basically most of the pics are from the internals of the 722.9 tranny and some other pics i took
this is the bottom of the tranny where the pump sits. also where the b1 clip sits that is replaced. when the clip comes out of place, it causes the tranny to jerk at low speeds
these are the internals of the tranny that have to be removed to get to the clips
this is the case of the tranny and valve body. this is from a e500 that had a hard bang when coming to a stop
in the middle of this pic is where the b3 clip sits which is also replaced when the b1 clip is replaced. i think I got it correct, if it isnt the b3 its the b1. either way the clips are the same. behind it to the left is the k1 assembly which another tech replaced yesterday in a CLK.
this is the pic of the engine with the tranny removed
here is the tranny out of the car and on the stand before it is torn apart
here is the torque converter
here is usually how we know if the b1 and b3 clips need replacing. what you are looking at is the adaptation values. if any one shift point is at -15-20 there is an issue, and usually when the 3-2 and 2-1 downshift are at -20 that means the clips have come out of place.
here are the clips and springs that is replaced 2 clips and 2 springs
here is the tranny with the valve body removed
