Post Transmission repair for 140

Hello to all, I am trying to get a fix on a transmission issue I am having on my 93 500SEL.The trans is a 722.3 4 speed with the B setting at the shifter. The trans. will not engage in any gear. It came about after a normal shift into reverse and then stopped operation. There had not been any indications of any problems and I have kept up maintenence diligently. I have checked the fluid lines to see if fluid was moving. It appears to be flowing, though I have not done a pressure check. I dropped the pan and the fluid was clear, no smell. There was a little sediment but minimul, no particle or chunks, in the pan. The one thing it did do was when I try to shift into a gear and then back into park I hear a clicking sound that stops after 15 to 20 seconds. It sounds like something simple has occured. ALLDATA info indicates the teflon seal needing replaced at B2. Could it be in the valve body? any ideas of what it may be? ANy thoughts would be most appreciatted. I will take a pressure check on the pump and get it posted back to all. thanks in advance. I am also looking for some parts if someone has a 140 body car they are parting out. Cheers, Paul
