    Default 1963 Pontiac Bonneville Convertible Transmission Leak

    Need some help. Noticed a very large puddle of transmission fluid under my car. It has the original engine, transmission and rear end. The puddle was rather large. The last time I drove it the transmission was fine. In looking under the car, it is leaking where the rear of the transmission meets the drive shaft. As I was looking at it, I could see the fluid dripping. Any advice/help would be appreciated. I assume it's tranny tail shaft seal, but I wanted to see what you guys think. What do you think it is? The puddle is large. Is this a fairly straightforward repair? Is it an expensive fix? Any help you can give would be greatly appreciated. Thanks!

    Not sure anyone is following this, not sure if anyone cares.

    Replaced the rear transmission tail shaft seal. Part was $11.99, and I had to get some ATF fluid. Replaced it a while ago, and I haven't had a drip since!

    If anyone wants any additional information, just let me know.

    Glad to hear it, lucky you, my 1957 is leaking from the front so it has to come out, not looking forward to that, Todd C
