1986 22re with A43D automatic transmission. There's a leak coming from the shift lever linkage where it goes into the transmission above the pan. I confirmed that the circled area below is where the leak is coming from by wrapping a shop paper towel around the lever and it gets soaked with ATF after a couple of days. I've looked through the Toyota Shop Manual as well as the A43D Transmission Service and Repair Manual and I can't find anything that would tell me if there's a gasket/o-ring or some other part that might have failed in that area or the steps needed to fix the leak. I would really appreciate any help in diagnosing and repairing this problem.

 

I actually have one of these transmissions in my garage. I've only pulled the pan though so I don't know what it takes to pull the shaft. I would think that there would have to be a seal. Maybe look up a parts list.

 

Looks like I need 2 new oil seals shown in the picture below. Available at NAPA and called "Automatic Transmission Seal, Manual Valve Lever Shaft - Metal Clad. Part number ATP 15234".
