Classic/Antique Car Repair: Powerglide leak at Kickdown linkage, rubber washer, transmission leak

Question
I have a 1964 corvette with a powerglide. I have a small transmission leak at the kickdown linkage. Can you tell me what it will take to seal it up?

Answer
Hi Joe:
Depending on the nature of this leak, there should be a rubber washer screw holding the linkage in place. That seals the transmission linkage. If this is the case, either tighten or replace that screw with one like it. If this is not the case, I would still replace the nut/screw with a washer-based nut/screw.
