722 Tranny front pump interchange?
 

I am getting ready to go out and pull the transmission from my '86 560sel. The front pump on the tranny is, as we say in the South, "slap burnt up"!

My question is, will the front pump from any 722 series tranny work? I have two automatics from 201 chassis cars ('85 190E and '87 190D 2.5) that are know to be good. All the pictures I can find of the pump appear to be identical, but as I have yet to pull the 560's transmission I just want to get a heads up as to if I need to go find a 126 chassis for parts.

Thanks in advance!

The 722.3 trans pumps WILL interchange...

but the pump from 722.4 trans in the smaller engined cars will not work.

Thanks M.B. Doc!! Time to go to the junkyard......
