1..2...3.. clunk

[p24-1953]

okay i have developed a new problem. i have a 53' w/ hydrive. when you put it into reverse as you let off the clutch with the brakes on, the car makes a loud thuds and physical shakes just for a slplit second. what could be causing this? clutch? transmission failing?

if i had to describe the sound i would say it sound and feels like if i had a broken motor mount and the engine was shifting.

Are your U joints in good shape?

havnt checked them, but wouldnt they "clunk " in forward also?

I had a hydrive many years ago. As I remember it did the same thing until reverse went out completely. Luckily back then they were in junk yards and not hard to find.

Just curious, ever thought of going to a standard three on the tree? There are lots out there and you would be rid of the tough to fix, hard to find hy-drive? Would you need a different flywheel, bell housing, crank? Just curious as I said.

i have been told that it is difficult to convert back to a standard three. I drove it today and the clunk was not as noticble as today. I hope that it is not the transmission going out. that would be a tough one to replace.

I think there is a hole in the back of the block that feeds engine oil under pressure to the trans. That would have to be blocked off too. Am I remebering right?

Maybe this will help.
