Hey guys not sure where to post this, but I've been under my 55 Special a lot this week, trying to get it read for Led East, this might be the year it makes it. I've been really fortunate all these years my Dynaflow never leaked. Well the other day I was under it and it looked like it was leaking by the "tailshaft" and it's actually low. The car sat for 30 years before I got it 10 years ago, so out of fear of moisture I changed the fluid and put in Dex Merc high mileage and it was never a problem. Then it sat for about 3-5 years so I changed all the fluids again and this time I used straight Dex Merc because the car only has 35k miles on it Could it be the fluid or coincidence? Is there a trick to get the seal to swell up again? I know the Dynaflow is a strange beast so I don't want to just be throwing stuff into it without asking guys who know.
