Martin, I am the one who you helped several years ago swap out a 1998 722.6 transmission with a 2001 722.6 in an 1998 S420 that was so innovative and worked great. Unfortunately a year ago I was rear ended by a HUGE silverado pick-up and the car was totaled. -Otherwise I am sure it would still be running.

I have just about finished rebuilding a 722.3 for my 1981 380SLC and this issue with a missing spring cropped up. I have been pretty careful in its disassembly and reassembly and I do not think I lost any parts.

I too noticed that this part is not on all drawings. In your experience what might be the result of putting the transmission back together without this spring?

Best regards,

Jeff
