53 Pontiac Hydra-Matic

Recommended Posts

Hi there

I'm owning a 53 Pontiac Catalina with an Inline 8 which I actually rebuild. I had also an issue with the hydra-matic so I decided to check the transmission. Always when pushed in Neutral or when towed I had a rattling noise coming from the tranny that stoped when the car reached a certain velocity. I opend it and located the source of that noise. There is a Parking Brake Gear and sort of blocker lever. And this lever causes the rattling noise.

 

Now. I am no sure, if this is a Problem. Usually I don't move the car in Neutral. Perhaps there is a problem with a valve that doesn't keep the blocker off the parking brake gear in Neutral.

Hope my english isn't too bad, it's not my mother tongue.

hello, the parking lever may have a worn out torsional spring, allowing the pawl to come in contact with the internal reverse gear.

Thank you Charles for your answer.

I guess you mean that torsional spring in the following pictures? Any Idee where I get such replacement parts?
